With my PUK I can design, make and repair jewelry faster, better and more complex.
Mohan Chandie Shaw

Having already worked with the PUK 2 from Lampert, I immediately bought the PUK 3 professional plus when it came out. It has almost the same possibilities and applications as a laser but you pay less. It is built as a tank so it has little to zero maintenance. With the PUK 3 I can design, make and repair my jewelry faster, better and more complex. In my eyes, the Lampert company stands for high quality and innovation in the field of jewelry manufacturing. Lampert offers individual support, and they understand what a professional goldsmith needs.

Veselin Tenev

We are so delighted to have the PUK and to work with it. Specially me, with those many years’ experience behind The PUK welder is my right hand and I couldn’t imagine not having it even for one day away from me! Actually, my dealer in the UK has told me when I bought the machine only two words …
“Have fun!” as a wish!
And thinking today, I am really having fun, enjoying working and discovering how pleased anyone can be to create things with it.

After my apprenticeship, I have learned one more enriching technique besides the typical craftmanship – using a PUK welder.
It makes my daily work much easier and I really enjoy working with it every time because it offers completely new opportunities, e.g. when working close to sensitive stones e.g. when working close to sensitive stones I can also close pores quite easily and/or apply additional material. The PUK device is very easy to use and allows countless ways to process or remodel jewelry without much effort.

All of us in the team benefit from the PUK 4 and its wide range of applications.
Steffen Dülk

We have to carry out a broad variety of works in our goldsmith’s workshop of the abbey. From filigree engagement rings made from platinum to rather big sacral utensils made from silver or tombac Therefore, all of us in the team benefit from the PUK 4 and its diverse areas of application. Iz is a great help to us in goldsmithing, repairing or making new church decorations.

Studio Loubser

Our PUK welder has become an integral part of our workshop … We are able to work accurately and effeciently, avoiding time-consuming manufacturing and repair processes.
Studio Loubser

Our PUK has now become an essential part of our workshop, and there is hardly a repair challenge that we cannot master safely with it.

The PUK is ideal for the finest work as it generates very little heat, especially in critical areas. Thus, it is possible to weld near precious stones and pearls. Because of the locally very limited heat generation, the workpieces can be held quite easily in the hand during welding – therefore no binding wire is needed for subsequent soldering, and there is no need for elaborate pre-positioning of the parts. We are able to work accurately and efficiently, avoiding time-consuming manufacturing and repair processes For very complex objects, we occasionally even use the PUK to position claws before we then solder them.

The small scale and snazzy appearance of the welder blends into our workshop with ease.

It is however, worth mentioning that using the PUK welder is a skill that has to be learn You have to spend time becoming accustomed to using the machine, in order to use it to its maximum capacity.

Practice makes perfect!

Lev Shneiderman

This tool is a real asset to any artist’s workshop!
Lev Shneiderman

For me, as a veteran metal artist specializing in both traditional and modern techniques, my PUK 5 from Lampert has become an indispensable tool for my workshop. The PUK 5 enabled me to significantly upgrade my manufacturing process and provide more freedom with my art designs. The PUK 5 shortens the time it takes to build a construction. It allows handling seams and soldering more effectively and in a shorter time.

This tool is definitely an asset to any artist’s studio!

Arkadiy Chernikkov

I consider this micro welder to be one of my best tool investments.
Arkadiy Chernikkov

I have purchased a PUK five years ago to expand my TIG welding to micro level, and never regret for that. Reliability, super easy to start, fast learning curve and lots of hidden capabilities for custom pulse programming – that’s exactly what I was looking for. I would also add the moderate argon consumption and the possibility of micro spot welding. Maintenance is minimal: simply refill the argon cylinder and keep the tungsten electrode clean and pointed.

For North American readers, Robert at Lampert Tools USA in Chicago is incredible at helping with ordering, shipping and delivery. After I received my device, he gave me a free one-day course on the basics of microwelding. In addition, customer service and supplies procurement are fast, friendly and professional. I consider this micro welder to be one of my best tool investments.

Michael Berger

I can hardly imagine a work process without the PUK anymore.
Michael Berger

Really, not a day goes by in the workshop without the PUK. How quickly this device has become absolutely indispensable was quite amazing, a work process without it seems almost unthinkable to me.

Especially with my kinetic work in stainless steel, joining with the PUK has become child’s play and has also enabled completely new ways of fabrication. Whether for the tiniest mechanical components, fine sheet metal constructions with only 0.3 mm thick sheet metal or large space-consuming jobs, the PUK is used by me everywhere and does its job reliably and in high quality.

The PUK – a tool that I have grown very fond of and would warmly recommend to all colleagues.

Esther Heite

I include the PUK in my design process, indeed it shapes the design to a certain extent.
Esther Heite

For me the PUK has become an inherent part not only in the workshop and for solving problems. I include it in the design process. Yes, it shapes my design to a certain degree

From the failed attempt to hide welding points and thus achieve an invisible connection, the subversive plan to deal with the connection points as obviously as possible was born. The result was a design idea that makes the welding spots my main design feature and sets them off like little diamonds. I see, in addition to the various utilitarian applications, that precise technology like the Lampert spot welder can create great aesthetic value. I want my jewelry to reflect that.

The PUK offers clean connections, precise work, new possibilities. It not only simplifies, it paves new ways in jewelry design.

Daniel Imboden, DIM-TECH

My expectations of the PUK U5+ were very high and were met across the board.
Daniel Imboden, DIM-TECH

My expectations of the PUK U5+ were very high and were met across the board. Working with the PUK U5+ is very simple and straightforward.

An artist carefully assembles his tools, as he expresses his thoughts and ideas through his hands by means of tools. The high expectations placed on oneself must also be placed on the tool. Therefore, I work exclusively with professional tools and machines.

For the production of my kinetic solar sculptures I prefer to use steel round bars up to 4 mm and sheet metal up to 1 mm thick. In the past years I have tried many techniques to be able to combine these materials optimally. I have used several processes, such as TIG welding, brazing with hydrogen, spot welding or the soft soldering. None of these connection techniques met my high standards.

One day I became aware of the PUK U5+ welding system from Lampert, which I had not known until then. The first-class technical support of the Lampert company was able to advise me “to the point” what the possibilities of the PUK U5+ are.

My expectations of the PUK U5+ were very high. However, these were fulfilled all along the line. Working with the PUK U5+ is very simple and straightforward. It feels like holding a thick pencil in your hand, easy to handle, safe and accurate.

Normally, I only rave about Swiss made machines. However, I was happy to include the PUK U5+ from Lampert, made in Germany, in my machine park.

Jose Marin

My favorite cocktail consists of: PUK, Argon and Titanium!
Jose Marin

I have been working with the PUK 2 since 2006, and my favorite cocktail consists of: PUK, Argon and Titanium.

If I hadn’t had the PUK, I wouldn’t have been able to make some of my best titanium objects.

I bought my PUK 2 in 2006, right when I opened my own workshop: www.josemarin.net.

I first used it in making gold and platinum jewelry, especially in the following three areas:

1) When I repair delicate parts with gemstones that should not be exposed to fire, I can work on the gemstones without having to set them out first.

2.) Pre-assembly of complex parts that I will have to solder later on a soldering station and with the help of the torch.

3) Creation of impossible pieces. For example, if you are mounting a platinum band with diamonds running over an emerald, this would be unthinkable using the traditional method by soldering with a flame.

Currently, the PUK is a great help to me in making my objects from titanium and Timascus. So far, I have been able to accomplish everything I set out to do.

I must admit that my PUK 2 is already a very old model, with restrictions for silver and bronze, but otherwise it is a perfect welder, which is also very robust – in 14 years I have not had a single defect.

André Rasgulyayev

Working with the PUK is just a lot of fun!
André Rasgulyayev

When I started my own business with my brother, the PUK 5 was our first purchase, along with two workbenches. We both had already had very good experiences with the PUK 2 and 4 and therefore knew that this wonderful device would become indispensable for us.

The PUK can be summed up in one sentence: “easy to learn and hard to master”. Anyone could tack weld and joint parts after a few minutes. But the incredibly diverse possible field of application arises over the time and growing experience Due to the very well calibrated default settings that the PUK 5 comes with, you can take countless challenges directly. With the experience at what angle, from what side and with which setting the respective welds work best, the joints are getting cleaner.

We work with the device on a daily basis and the results are impressive, yet we feel that we have not yet exhausted the “PUK potential”.

Ramon Zollner

With the PUK, I have taken custom remote control model building to the next level!

I am a perfectionist and try to build my remote controlled models with the highest quality and detail. I was looking for a device that would allow me to achieve this goal. I used to not be able to work with steel or stainless steel, and because of the fine detail and precision work, I could not weld with a regular TIG welder. A colleague of mine recommended the PUK, which he saw during a demonstration at a trade show. I contacted the LAMPERT company, explained the situation, and was recommended exactly the configuration I needed. Then, in early 2017, I bought the M200, which was shipped directly to me in Australia. LAMPERT even showed me how to use the device via Skype in a way that was easy to understand. Now, after almost 3 years, I no longer want to do without it. The precision, scale fidelity of the welds and the strength meet my requirements exactly. I can now work with different materials, with stainless steel being my favorite. I can only recommend this machine to any demanding and professional modeler.

Tony E. Ouzounian

Since 2002 we have been using the first model of Lampert fine welding equipment. The PUK 111 is a great welder that we can rely on in our jewelry factory. Almost every day we work with it at least 10 goldsmiths.

The PUK from Lampert – a must for every jeweler
Dean Irvine

The PUK from Lampert – a must for every jeweler

I invested in a PUK 5 and this has already paid off for me after 6 months. Beyond traditional soldering with a flame, the PUK opens up new perspectives for me when repairing or restoring jewelry because of the low heat generated during PUK welding and because of the ability to precisely set individual spot welds and produce the finest weld seams. I deliberately chose the PUK 5 and not another product because of its product quality, good customer support, maintenance-free technology and, last but not least, the welding results that can be achieved with it.

Gregory J. Lafford

The PUK proves to be invaluable to me – regardless of the metal or alloy used.
Gregory J. Lafford

Over the last 15 years I have consistently worked with the various PUK models, and at the moment a PUK5 is being used in my workshop. A more versatile machine for a jewelry store has to be found, and only my own imagination sets the limits on what the PUK can be used for. Whether it’s new fabrications or repairs, setting stones or engraving, whatever, the PUK proves invaluable to me – regardless of the metal or alloy used.

You do not believe me? Then just drop by my workshop and see for yourself!

Min-Ling Hsieh

I have to say, without the PUK, I couldn’t imagine doing my job!
Min-Ling Hsieh

I was able to work with the PUK111 for the first time in 2003 at the Staatliche Zeichenakademie Hanau and immediately fell in love with the device.

With the PUK, my ideas can be realized in metal at any time. I can also combine metal with other materials, such as stone, glass, ceramics or textiles.

I work a lot with thin sheets and wires, so the PUK is the ideal tool for me. I have owned every PUK model from the PUK 3s onwards, i.e. also the PUK 04 and currently the PUK 5. With each new model I see further progress in the fine adjustments and I can weld with even greater precision.

I have to say, without the PUK, I couldn’t imagine doing my job!

Luca Cristino

I believe that a PUK belongs in every workshop to make jewelry making as well as repairs faster.
Luca Cristino

You can take away anything but my PUK !!!!

I use it for all gold, silver, stainless steel, titanium and platinum work.
I can work on settings without difficulty, without having to remove the stones first.

The PUK is perfect for fixing parts, for various microrepairs, and it allows me to work on watches (crowns, shafts, gears and bracelets) as well.

My model is the PUK 3s professional plus: since the day I bought the device, it has already paid for itself in less than six months.

I believe that a PUK belongs in every workshop to make jewelry making as well as repairs faster.

Mark Sansom

I consider the PUK an indispensable tool in jewelry making and repairs and can’t imagine my work without it.
Mark Sansom

In jewelry repair, it’s critical to be able to build up small areas with metal – I didn’t have that opportunity for the first 25 years of my goldsmithing career.
Later I heard that there were new welding machines on the market. So I bought a PUK 3s from Lampert and still use it years later for most of the repairs I do.
The device paid for itself in the first year because it saved me so much time.
The PUK opens up whole new possibilities, such as bracelet repairs without the need to completely rework everything afterwards, building up cracks in gemstones like emeralds without having to remove them first, fixing welds before soldering, closing pores, and much more.
In most cases, working with the PUK is faster and cleaner than soldering.
I consider the PUK an indispensable tool in jewelry making and repairs and can’t imagine my work without it.

Lee Molseed

The PUK saves a lot of time. This allows me to do a lot more productive work in my day-to-day life. Every goldsmith should have such a device!
Lee Molseed

I have been a goldsmith for 10 years now and did a classical apprenticeship with a master in the jewelry district of Birmingham.
With this fantastic new PUK, I can now eliminate open flame work as much as possible, and I use my PUK for the majority of my repairs.

Working with it is faster, cleaner and even near delicate stones such as opals or emeralds, repairs are safe.
At the same time, the PUK saves me a lot of time. This allows me to do a lot more productive work in my day-to-day life.
Every goldsmith should have such a device!

Gabby Williamson

Soldering in orthodontics is now a thing of the past for me, and many jobs were not possible in the way they were when I could only solder in the lab.
Gabby Williamson

Soldering in orthodontics is now a thing of the past for me. TIG welding is superior in every respect. There are countless possible applications for the PUK D2. Only minimal preparation is required and the joints are more stable, at the same time much finer.

Since I have been working with the PUK D2, not a single appliance has broken. Many works were not possible in the form when I could only solder in the laboratory. Because of the low heat development and the hardly occurring distortions, I can also weld very small attachments to my apparatuses. Even very delicate constructions can be welded easily and with little preparation time. Particularly time and money saving is the fact that hardly any finishing and polishing is required. Welding under the microscope makes the work even more precise.

But not only the PUK D2 is great, also the service and the employees of Lampert were and are a great help to me. I was in contact with them a few times and they were always extremely helpful. Since they want their customers to like the machine as much as they do, they never tired of keeping in touch with me until all my questions were answered.

David Fried

My PUK has not only solved many problems in the realization of art projects that I already had in mind, but has opened up unimagined possibilities for many more ideas!
David Fried

Do you know that sometimes your best ideas reach the limits of what is technically feasible? As an interdisciplinary artist, my visions often move far beyond these technical boundaries. In many cases, I have to develop the necessary tools myself and pursue my projects with considerable limitations and improvisational skills for years. In 2013, I wanted to create polished stainless steel art objects that would have been very difficult to repolish after ordinary TIG welding because of the often difficult-to-reach welds.

Amazingly different is the PUK solution: I was more than pleasantly surprised when I came across the PUK, and the device demo in my studio that I was subsequently offered was terrific. This is a device like I could never have invented or even imagined myself! And it not only solved many problems in the realization of art projects that I already had in mind, but at the same time opened up unimagined possibilities for many more ideas.

And not to forget: The PUK is produced in Germany to the highest standards, and the customer service is unbeatable! For me, Lampert is clearly an innovative company that, while paying very close attention to quality, is also aware that its products are not only “problem solvers”, but also a key to the creativity of its customers.

Robert Hallett

No weld and no porosity. The PUK already paid off here.
Robert Hallett

I have been working with precious metals for close to 50 years and some of my tools were passed down to me from a goldsmith who worked with them back in the 1920s. So the PUK ended up in a workshop where the anvil, finishing hammer and draw iron are used every day.

When the PUK arrived, I had a problem that needed to be solved. I had just finished a custom ring – set with a 2.25 carat diamond in two very wide pips. However, I had not built up enough platinum over the diamond for a secure hold. After about five hours of practice with the PUK, I was already able to apply 0.75 mm pure platinum to the tips of the claws and flatten it over the diamond. No weld and no porosity. As if the extra platinum had always been there.

The PUK already paid off here.

Victor Magnes

I don’t just use my PUK welder for difficult jewelry repairs, it is used every day in my workshop.
Victor Magnes

Experience with the PUK 3 welder at the Jewellex jewelry show 2009:

“I was on the hunt for a tool that would make my life easier when repairing thin chains and setting up crawlers without costing too much time and money.

I think achieving this is a bit difficult in the last 5 hours of the last day of the Jewellex show, yet against all expectations my dream was fulfilled. While walking down one of the aisles past a jewelry showroom, I saw a man doing something funny, something was producing sparking flashes of light, catching my attention.

A dream began to come true as I stood there watching this gentleman looking through a microscope and did something that blew my mind: he welded two pieces of metal together. I started asking questions – Is it possible to replace soldering, weld a bracelet, without dyeing out the colored stones? The answer was ‘yes’. Is it possible to weld new lobes on a set ring, even with colored stones? And again the answer was: ‘yes’! – I asked if I could try it, so he got up and showed me how to adjust the microscope to my eyes and started welding. Ok, at first my welds were a little messy, but I sat there for over an hour experimenting, literally glued to that chair. Honestly, at that point I immediately had millions of ideas on how I could use my PUK 3 and how it would be useful for me to simplify my life and make more money with less stress.

It’s been two and a half years now, and I’ve used my PUK welder not only for difficult jewelry repairs, it’s used every day in my workshop. I have also used the PUK in the world of opticians, there it helps repair damaged eyeglass frames of all brands and metal types. It’s amazing, most of the repairs aren’t even visible because it’s a micro weld. But the real magic of PUK welding is that so little heat is generated during welding that you can hold the jewelry in your hand without getting burned.

All I can say to the team at Lampert is, never stop developing new technologies. You guys are great, I wouldn’t know what to do without my PUK welder.”

The PUK D2 is even easier to operate with its touchscreen. Simply select the welding parameters and off you go.
Sokratis Gondis

The DENTA PUK was already a great machine. I have worked with the DENTA PUK for more than 2 years and could not imagine that there is an even better device. But when I tested the PUK D2, I had to change my mind after all. It is even easier to operate with its touchscreen. Simply select the welding parameters and off you go. Even orthodontic bands with a thickness of 0.1 mm can be welded quite easily. We no longer have to think about soldering in our lab….

Jeffrey Herman

I was so impressed with the friendly and helpful support team – both in the US and in Germany – that I was absolutely convinced.
Jeffrey Herman

As a perfectionist, I am constantly developing and researching techniques that will allow me to complete my tasks faster and achieve better results. I often receive items that are so time consuming to repair that the customer decides against it considering the cost. That’s why I decided to try out a friend’s laser welder a few years ago – hoping to save time doing certain repairs that way. However, it turned out that commuting between his workshop and mine took up an enormous amount of time. In addition, I could not repair larger objects in the small welding chamber of this laser welder (this limitation applies to all laser welders).

This colleague also owned a PUK 2. He lent it to me, because buying a laser welder would not have been an option for me for cost reasons. I also immediately received customer orders where I could put the PUK through its paces. The very first object I tried the welder on was a Judaica item that had the glass end decoration broken off. This very thin piece, about the size of a coin, was in a sawtooth-shaped enclosure. Normally, I would have had to take the glass out of the socket (very risky because of the risk of breakage), then braze the end piece in place, and finally put the glass back in the socket. This approach would have required a lot of working time.

Fortunately, the PUK came to my rescue here. This allowed me to weld on the end piece and rebuild one of the partially missing saw teeth of the glass surround with some sterling silver.

This, of course, would have been unthinkable with flame brazing, regardless of size. Dealing with this new technology proved to be extremely exciting.

A more extensive repair attempt was made on a 19th century silver milk jug.

The problem here was that three of the four legs had been cut off and soldered back on with lead solder. That had not been a good idea. While I was able to remove the lead from the legs, I was unable to visually inspect the leg support internals, which would have provided information as to whether the legs could be reattached by silver soldering. Normally, I would have had to use a tin-silver low-temperature solder, because working with high-temperature silver solder could have caused the silver to be “”consumed”” by any lead residue. Here, however, thanks to the PUK’s arc pulse welding technology, I was able to successfully weld with rigid silver wire, resulting in an invisible and much more stable attachment.

In short, I was impressed by the PUK. Since I work primarily with silver, a material that is the most difficult to weld due to its virtual lack of resistance, I was ready to purchase an even more advanced machine: The PUK 3s Professional. This fine welding unit was specially developed to take into account the special features of silver as a material. However, before purchasing, I wanted to contact technical support to clarify numerous issues. After all, the PUK 3s Professional would be the most expensive device I had ever bought. Therefore, I wanted to be absolutely sure not to make a wrong decision. I was so impressed by the friendly and helpful support team – both in the USA and in Germany – that I was absolutely convinced: This device and its manufacturer were made for me. The warranty period of three years also caught my attention!

Of course, when the PUK arrived, I immediately pounced on the box and set up the machine along with the optional swing arm that allowed me to machine these larger parts. It is a beautiful device and is more like a component of a fine stereo system than a tool for a silversmith. The PUK is easy to use and understand, and I quickly realized what an asset it would be to my modern equipment fleet. I already know that when the next snuff box arrives with a cracked hinge, I won’t have to take it apart to repair it. A few touches with the electrode are enough to make it functional again. Amazing, isn’t it? Stitching long seams together, which are then hard soldered with silver, saves the enormous amount of time that was previously required for “wiring”.

Today, it’s hard to find a company that not only makes durable and great-looking products, but also provides technical support from employees who themselves work with the equipment they sell. And that is at least as amazing!

Carsten Kissner

Saw, file, pliers, PUK, if I had to make a ranking of the most important hand tools in the goldsmith’s everyday life, the PUK from Lampert would be right up there with them
Carsten Kissner

Saw, file, pliers, PUK, if I had to make a ranking of the most important hand tools in the goldsmith’s everyday life, the PUK from Lampert would be right at the top. Because a small spot weld in between shortens many a work step enormously. I have been working with the PUK for almost 8 years and therefore believe that I know its areas of application sufficiently, especially since I first worked with the predecessor model, the PUK2, for a long time and have recently switched to the Professional plus, which is much better tuned and more mature. If, like me, you work with traditional handicraft techniques and the associated small machinery, you will find something like a Swiss army knife in the PUK. Just so small “annoying” standard repairs like the torn chain repair – spot weld on it ready – I would not want to miss this nice little helper with the name of a child’s bike (PUKY).

Petr Dvorak

What is unique on the PUK welding technology is a very wide applicability.
Petr Dvorak

PUK welding is not just a new joining technique, it is a fundamentally new method of metal design.

What is unique on the PUK welding technology is a very wide applicability, which can be multiplied in the combination with all conventional gold and silversmithing techniques in many new types of design, whether with classical or less orthodox materials.

PUK Technology is a contribution, an opening of new working horizons, for a highly qualified professional in any metal field, but also for a layman or an interested person who wants to deal with metal forming from scratch.

Personally, PUK welding technology has enabled me to do a whole new range of work with titanium and other metal combinations, where I could really unleash my creativity, and I am still not at the end of the possibilities that the PUK welding machine can offer.

PUK Schweißtechnik is only at the beginning of the real use of its creative and innovative potentials.

PUK Fine Welding Workshop 28.11-3.12.2011 University of Applied Sciences for Gemstone and Jewelry Design Idar-Oberstein. Workshop leader Petr Dvorak.

The companies Lampert (4x) and Horbach (1x) have provided new welding machines 3s plus, all with Mezzo microscopes and three lamps, in addition we have had two devices of the PUK 2 series.

Of all the workshop participants, no one had any practical knowledge of the PUK fine welding technology or any detailed information about the function of the device. Except that on the table in the goldsmith’s workshop is a device that few use.

About 16 students attended the workshop, and others learned about the function and possible applications.

For all participants, as already mentioned, this was the first contact with a different type of welding technology.

At first, only the function of the device with the different pulse variants was tried out, with the aim of learning the feeling for the pressure intensity when applying the electrode to the material, so that the electrode does not “stick” to the material.

After that, different types of welding such as wire and sheet metal joints and graphic treatment of the metal surface were tried,
then later made small compositions from sheet metal and wire.

The first steps with the new technology were tackled with varying degrees of skill.

In general, it can be said that the students who had a longer practice with brazing technology were better able to use the content basis or the advantages of fine welding technology for their trial work.

Understanding or grasping the PUK welding principle, how and when for which materials this technology can be best used, depends solely on the possibility of having sufficient time to practice with the PUK device.

With the increasing knowledge of the application potential of the welding equipment, creativity and the range of combinations are continuously being developed.

Thus, the FH management is recommended to purchase a PUK device of the 3s plus series.

Gerdi Glanzner

Especially with the reproduction of the imperial crown and the other insignia, the PUK was and is a great help to me. To solder the many, mostly very filigree sockets onto the base plates, the PUK is indispensable for me. Especially with the large silver parts, there is always a little warpage that makes soldering difficult….

With the PUK I can fix the sockets and trim parts securely so that they do not slip during soldering.

Acquisition of the PUK 3 professional plus and how it was integrated.
One day, an advertisement with the general trade press fluttered onto my desk. I was about to put it down when I noticed a box with two buttons and a large display. Looked interesting. What was that box and what can it do? Lampert Werktechnik didn’t tell me anything at that time either. But that was to change quickly.

What I read in the device description made me excited. So you can weld with this device, with and without the addition of external material. Suddenly my interest was aroused. The device promised a lot of possibilities that I had not had before. Above all, to make metal joints that could not and cannot be made even with my hydrogen welder. I suddenly had concrete ideas about what I could do with the device. So I drove to Münster and looked at the device in the flesh. There they were, the three, one more beautiful than the other except for the small “PÜKchen 111” but I didn’t feel like it. No, it was the two devices “PUK 3 professional” and “PUK 3 professional plus” that aroused my interest. “Plus” stood there for a bit more bang.

Since I could try out the devices on the spot, it was already clear after a short time, the welding machine with the additional B… it should be. I now had to wait 14 days for the device. Hm, the next question was, where do I put the device? Such a fancy machine on my scurry table for electronics, big clock repairs, plating, and other rough work, you can’t have that. The infrastructure was already prepared. Cables, electricity and compressed air were all already in place. The hose for the argon was quickly laid.

After a few hours of planning, my workshop became a carpentry shop for several weeks. I made a drawer for the 10L argon cylinder and integrated it into the workbench. When the base cabinets were finished and the 95Kg tabletop was fitted with millimeter precision, it was the turn of the top.

In the meantime, my PUK 3 professional Plus was delivered by Lampert. So I was able to put the Boliden in the attachment for the first time and make the front frame. Slowly, the essay began to take shape. The aluminum plates with the individual displays were
already made and fitted. The next few days saw the removal of the attachment with compressed air, propane gas , hydrogen gas, argon and the electronics. But also the front panels with all controls were finished. After eight days, the complete attachment with the PUK, the intermediate shelf for soldering accessories and the drawer box was finished.

So that there are not so many cables lying loose on the table, I have combined the supply lines to the microscope for the illumination and the shutter in a braided tube. Plug into the coupling, test run, done.

So I was inspired by the PUK 3 professional plus to set up and build a complete goldsmith’s workstation.

With the PUK3, we can perform exactly the precision work that is required today in the world of haute joaillerie.
Claudiu Bologa

We have been using Lampert PUK equipment for over two years and have since discovered the limitless possibilities that exist when welding objects made of gold and silver.

Work that until then required a lot of attention and concentration, but still not infrequently ended with repeated failed attempts, has since been forgotten.

With the PUK3, we can perform exactly the precision work that is required today in the world of haute joaillerie. In addition, the PUK 3 is used for very delicate fine welding work, for example on very small clasps, on jewelry with pearls or enamel, and on those with gemstones that would not survive soldering work on the open flame…

PUK combines fun with challenge and completely exciting possibilities! Do without the PUK? Unthinkable!

Working with the PUK opened up new possibilities for me!

I have been flirting with the purchase of the PUK for quite some time.

However, the decision was quite easy for me about a year ago. The decisive factor was the competent advice provided by Thomas Krükkert to the Flume company. After a personal briefing by Mr. Krükkert in my goldsmith’s shop, I had the opportunity to test the device for a week. Thus: I was thrilled!

The week was quickly over and the PUK was picked up again. It was immediately clear to me that I had to have this device. Couldn’t wait for it to finally arrive. Working with the PUK is very easy for me personally and I enjoy it immensely. About 6 months later, during which I had refined my skills, I took part in an advanced training course at the Flume company in Essen. I can only recommend this, because the exchange with like-minded people, as well as the different questions and contingencies of the participants that arise in practice, were critically examined from different angles and gave me another enormous boost of experience in dealing with the PUK.

Working with the PUK opened up completely new possibilities for me. Be it in the field of repairs, but also in the field of processing gemstones completely innovative. There are almost no limits. The service sector should not be disdained either. From soup spoons to eyeglasses, partial repairs are no longer an issue.

Once you have familiarized yourself with the material, there are few materials that “unfortunately” cannot be processed. I emphasize unfortunately, because working with the PUK becomes addictive. I catch myself thinking: I’ll just shoot that!

Everyone who has started with the PUK knows: of course, this does not always work! Again, there are limits, but the enthusiasm to overcome this problem becomes a challenge! Thus, the most terrible repairs become exciting test objects!

Trying it out for yourself! Will I make it? In 90 percent: YES! Last week I instructed my journeywoman in PUK. She was immediately infected.

Also with her: PUK fever!

Conclusion: PUK combines fun with challenge and completely exciting possibilities! These possibilities can be increased and exploited depending on the user’s performance. Do without the PUK? Unthinkable!

My thanks go to the Lampert company, for the realization of such an innovative device and, of course, to Thomas Krükkert, from the Flume company, who assists me with his expertise in every question.

Thanks to PUK, I can realize my creative ideas more easily and there are no limits to the realization of my imagination!”
Yura Golub

I’ve been looking for a solution to bring objects chased from sheet bronze together so that the body of the object and the seams/joints form a unity of color after patination. I planned to make not only jewelry but also larger objects such as vases, bowls, jars, etc.

I was allowed to test the PUK for a week and experiment with it, the result convinced me, I have been working with it regularly for three years now and could see that PUK saved me a lot of time (and nerves) in the production of my objects. The work process is very clean, the welding of long joints resembles “embroidery”, which I sanded down at the beginning so it looked more like a bronze casting. However, the fine “seams” create an additional charm and if it fits, I leave them, because they give the object a distinctive touch.

The days when the PUK is not used can be counted on a few fingers.
Vadim Pamortsev

Our goldsmith workshop is located in the north-east of my home, and it all started with a hobby in the nineties:

Like all “do-it-yourselfers”, I worked with an open flame, solder and flux, etc. at that time. Then in 2009 we opened our own workshop. On our homepage www.vpgold.ee you can get more detailed information about us.

Today we have quite a large work experience. That is, we perform work of very different complexity, and we try to meet every customer request.

In December 2012, I finally decided to buy a PUK04, and I can say with full conviction that I am extremely satisfied with the device!

Since then, most tasks are only done with the PUK, and the days when the device is not used can be counted on a few fingers.

Now we do repairs that used to take us an hour in 10 – 15 minutes. In addition, we do not consume solder or time to clean up, as would be necessary after soldering with the flame.

Also, I must note that the PUK04 is simply irreplaceable when repairing jewelry with stones! Of course, we still don’t completely dispense with soldering, because there are always jobs where it is unavoidable.

We even weld armored chains with a thickness of more than 0.6mm without compromising quality. On the contrary, a chain does not get discolored, as would be the case with soldering: this is a huge advantage! It is somewhat more difficult to weld silver – but this is also feasible. This is probably due to a lack of experience with this metal, but we are always learning, and the sky’s the limit.

I also bought the swivel arm for the microscope. This one helps me a lot when restoring bulky parts. And one could still write so very much good about this device, but unfortunately I lack the time…

I would like to express my special thanks to the staff and management of Lampert for their support in purchasing the device! Very conscientious and helpful people who understand your business.

I chose the PUK because you can weld anything with it: Gold, silver, titanium, steel, … Thanks to the microscope, it’s very precise!
Bram Timmermans

When I bought my PUK, the new PUK04 was introduced at the same time. But the Lampert company kindly changed my order so that I got the new model. I really love the functionality of the device! I chose the PUK because you can weld anything with it: Gold, silver, titanium, steel, … Thanks to the microscope, it’s very precise! I can make finer welds than with classic soldering. Once you get the hang of it, the work is very fast and precise. Now I can make repairs to jewelry that would not be possible without a PUK or a laser. The price is also cheaper than that of a laser welder. Once used to it, you can’t work without a PUK!

The PUK has changed our everyday workshop life:
Some things are now faster and easier, many things became possible in the first place!

I made my first contact with the PUK during my master class: Thanks to the good cooperation between the Lampert company and the HWK Würzburg, it was possible for the master students to practice on the equipment for a whole day and gain initial experience. Although I had heard about the existence of so-called spot welders before, I had never seen one.

During our “first acquaintance” I was taken with the simple, intuitive operation and diverse function. When I took the job at the goldsmith’s Jutta Rother in Neumarkt after completing my master’s examination, the PUK was at the top of my wish list. Purchased soon after, the PUK was immediately put into operation. In an initial burst of enthusiasm, I began welding almost everything: ring bars and settings, clasps and claws, eyelets and pins,…

After two years of experience with the PUK, a more considered way of using it has set in: The PUK is still used practically every day, but one learns where it is better to use it and when other techniques make more sense: In most cases, a soldered mount is more durable when connected to the ring rail, but thanks to a few PUK welding points, it sits exactly where it should and cannot slip during soldering. Pores that appear in the almost finished workpiece, e.g. only during polishing, are – cleaned and with the appropriate welding setting – often history with one “shot” – in the past you had to use a flame and a lot of cleaning work started all over again…

Today, we always use the PUK where it is most effective: for special materials such as steel, for reinforcing ruffs, or even for setting fixing points before soldering. Here, a few minutes at the PUK often saves hours of hassle. And the PUK also enables us to do work that was simply impossible before: welding on wires and eyelets in close proximity to pearls and stones, repairing the finest of joints without weakening surrounding areas with heat or destroying surface finishes – in short, a wide range of very precise work on sensitive structures.

Mr. Heinrich from the Flume company was very helpful during the installation and also gave us extensive instruction. With this solid foundation, anyone can quickly learn the ropes at the PUK and gain the necessary experience. You quickly get an understanding of the different programs and choosing the right settings (we are working on the PUK 3s Professional Plus, the PUK 04 has become even more comfortable here!)

I found a very competent advisor in Mr. Weise from the Lampert company for questions that still arise from time to time in everyday work with the PUK. He regularly provides me with the latest tricks and tips (the best tips are also presented in the email newsletter!), and always informs about technical news and accessories.

The PUK has made our goldsmiths more effective in both repair and fabrication and has added a variety of capabilities. I have built up an almost loving relationship with our “Pukki” and would not want to miss him. Every goldsmith working by hand has a valuable helper at his side with the PUK!

Martin Lerch

The use of the PUK allows me to realize new barrel techniques since metals can be welded directly to gemstones.

When processing titanium as a jewelry metal, welding technology is essential because soldered joints are not feasible.

However, I mainly use the PUK to fix the individual parts of a workpiece before soldering. It greatly facilitates the assembly and saves a lot of working time compared to temporary connections with binding wire or staples.

The small dimensions of the PUK allowed me to install the device directly on the workbench, which means that no change of location is necessary for commissioning.

PUK welding is madness!

I had a total loss in my business 5 years ago because of the flood, spirits were down and I had to really pick myself up to overcome the losses….

The list of machines and tools I had lost in the flood was long, and I took my time with my new setup.

When I browsed the catalog of Bijoutil and reached the page of the PUK, I became a little curious, as noble as this thing looks!

I tested, and without long hesitation, I bought it with the hope of amortizing the not-so-cheap…

And you know what – it was more than worth it!!! I now work at least 3 hours a day with this device and couldn’t imagine working without it!

I had been commissioned by Nina Campbell to make a plum blossom branch or tree intended for China, where she was designing the interior of a new house. Trunk and branches should be made of bronze and decorated with yellow, green and red flowers of 18-karat gold. Attaching the flowers to the branch would have been difficult without the PUK3 welder. To do this, I would have had to drill, tack and glue the flowers and leaves, which I would not have liked.

The PUK3 was the solution that enabled the effortless processing of both metals. With this tool I was able to weld on the smaller branches and texture the seams. I enjoyed texturing the most: by simply changing the settings, I was able to give certain areas the appearance of moss, and by adding metal, I was able to create bulges and bumps. I also attached the legs of the grasshopper and the butterfly with the welder.

The little tree was too large to position under the microscope. So I had to come up with a way to use the welding electrode pen freehand. This required me to wear two pairs of eye loupes and green goggles, clipped together. The lighting was difficult. I first tried a 200-watt incandescent lamp with an aluminum foil reflector, but that didn’t prove to be a viable way to go. So I used a very bright headlamp, like the ones used in caving – with much better results: This lamp always illuminated my working area brightly in the direction of my view and allowed me to work easily on the entire tree.

I also used this solution to tack the long seams on the drawn tube I used to make the stems of a 120 cm buttercup before soldering, as well as when making knee joints for some spiders that had been commissioned from me.

I still have quite a few ideas about how different metals could be joined together with the PUK3 welder. I’m looking forward to putting these ideas into practice.

Just using this device was an amazing experience.

Productivity, i.e. quality and speed, has been increased, and the device works very reliably.

In March 2010, I purchased a PUK3 professional plus welder with the accompanying welding microscope.

Until then, we had laser welding done off-site, which worked pretty well most of the time. However, in some cases we were not satisfied with the execution of the welds, moreover, we left a lot of time on the road. That is why we decided to purchase a laser welder. However, due to the high prices, we then gave preference to the purchase of a PUK welder.

Since we now work with the PUK, we can perfectly do all the welding work ourselves that we would otherwise have had to give away, without the unnecessary loss of time transporting parts back and forth. In addition, in this way we have eliminated the risk of our products being copied by third parties.

Before we had the PUK, we soldered everything with the flame. Soldering, however, carries a high risk for polished workpieces or set stones. With the PUK you can avoid this risk, welding saves time compared to soldering, is more practical and the results are impeccable. Welding also proves to be a great advantage for ring width changes.

I can list here the following PUK advantages: Especially workpieces with set stones can be welded without risk, productivity, i.e. quality and speed, has been increased, the device works very reliably, it is handy and can be easily used in any place, material consumption is reduced.

The assembly of two-colored stone settings or the final welding during the manufacture of a product are just a few examples of the benefits of the device.

The training by (our dealer) the company Teknik Dökum was very helpful for us. Since March 2010, we have not needed any further support and there have been no problems with the PUK. The manufacturer, Lampert company, has produced a user-friendly and reliable device.
