A compact TIG pulse welder: Just where conventional TIG welders reach their technical limits, especially of their lower power ranges, our technology for ﬁne and ultraﬁne weldings comes into its own – regardless of the size of the workpiece.
On workpieces with a thickness of down to 0.2 mm or even less it is a simple process to produce high-quality welds. That way welding spots with a diameter of approx. 0.2 mm up to more than 3.5 mm can be set (depending on material and setting).
Our welding technology is already successfully in use in over 80 countries in a wide range of different scopes – here are just a few examples:
As soon as the tip of the electrode of the welding hand piece touches the workpiece, the welding process starts automatically. At the contact point, under an inert gas atmosphere, a melting process takes place.
In addition to many sorts of steel, different alloys of titanium, aluminum, copper and tin, as well as various precious metals and alloys are suitable for welding. Generally, all alloys suitable for laser or TIG welding can also be welded with the PUK U5. If necessary, welding wires can easily be fed or added.
The operating concept of the PUK U5 combines the advantages of a modern touchscreen with the tried-and-true operation via a rotary controller. Thus the intuitive and safe setting of the device is guaranteed at all times.
Correctly set the device in two steps:

The patent-pending system for welding process monitoring
· New software for contact monitoring of the hand piece
· Prevention of welding errors through interruption of weld if excessive pressure is applied to the electrode
· Increase in service life of electrode tip
· Prevention of tungsten inclusions on sensitive surfaces or on workpieces and materials that still require further processing
· Improvement in the overall weld quality through more uniform processing
· Error prevention in the handling: Increase in process reliability and more consistent quality for larger quantities
· Learning function: More rapid and simpler learning of correct welding procedure, especially for beginners
Faster progress to better results – "blind operation" with single-handed operation. Concentration remains focused on the workpiece.
Even higher-performance LED lighting in our new premium welding microscopes. More uniform illumination of the working area - more flexible use of the microscope. These microscopes can also be used as fully equipped workplace microscopes - not just for welding.
Setting of parameters for "Power", "Time" and menu navigation with one single rotary controller.
Preselection of two different welding cycles.
Speed function (only PUK U5+) – increased heat input into the workpiece for an improved welding performance when welding on highly conductive metals and alloys (e.g. copper).
NEW: MICRO MODE

After using the Lampert PUK 2, 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 design, create and repair jewelry faster, better and more complex. In my point of view Lampert stands for high quality and innovation in the field of jewelry making. Lampert provides individual support and understands what you need as a professional.
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 vocational training 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. The machine provides a special default for building up worn settings or for reattaching a broken ear stud without having to solder. Furthermore, I can facilely close pores and/or apply welding wire. The PUK's operation is very simple and it enables me to easily work on jewellery in a lot of different manners.
I’m an orthodontist and I love working with my patients. But I also like to work behind the scenes making some of the appliances I use. PUK D5 opens a whole new world of orthodontic appliances’ design possibilities. Design it and then is easy to make it. Nothing is impossible. PUK D5 machine is the ideal partner in the digital printing era and it makes me feel like an artist in orthodontics’ field. It helps me to achieve great results.

For my watchcase restorations I use the PUK on a daily base. It makes my day so much easier due to its quick and easy accessibility. I can recommend it without any doubts!
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. That’s why our entire team benefits from the PUK04 and its versatile fields of application. It is extremely helpful for us for goldsmith’s productions, repairs or for the manufacture of new decorations for churches.
Our PUK welder has become an integral part of our workshop, there is no repair challenge that we cannot face with confidence.
The PUK welder allows for small scale precision work, focussing heat in specific areas, allowing to weld close to gemstones and pearls. The concentrated generation of heat enables us to hold the pieces by hand whilst welding, thus there is no need for binding wire or the complex positioning of the pieces whilst soldering. We are able to work accurately and efficiently, avoiding time-consuming manufacturing and repair processes. We even use the PUK welder for our pre-positioning of claws before soldering on complex pieces occasionally.
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 learnt, you have to spend time becoming accustomed to using the machine, in order to use it to its maximum capacity.
Practice makes perfect.
As a veteran metal artist specializing in both traditional and modern technics, I see the Lampert PUK 5 as an essential tool for my studio. 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 a real asset to any artist’s workshop!
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. Besides, I would add reasonable argon consumption and ability for micro spot-welding. Maintenance is minimal: just re-fill the argon bottle and have your tungsten clean and sharp.
For readers in North America: Robert from Lampert Tools USA in Chicago provides unbelievable help with order, shipment and delivery, and after I got my machine he gave me free one-day course for micro welding basics. Further customer support and getting consumables is fast, friendly and professional. I consider this micro welding machine to be one of my best tool investments.
There’s really not one day going by in the workshop without the PUK. How quickly this device has made itself indispensable was astonishing - I can hardly imagine a work process without it anymore.
Jointing my kinetic works made of stainless steel has particularly become child’s play with the PUK and opened completely new ways of fabrication. No matter if it’s tiniest mechanical elements, sheet metal constructions with a thickness of only 0.3 millimeters or big room sized works, I apply the PUK everywhere and it gets the job done reliably and with a high standard.
The PUK - a tool that I’ve grown fond of and that I want to warmly recommend to all colleagues.
