Where can I return my old device at the end of its use?
All welding equipment can be handed in for disposal at the end of its service life at Lampert Werktechnik Gmbh, Ettlebener Straße 27, 97440 Werneck from Monday to Friday from […]
What can cause the electrode to split or break?
The electrodes used are a special alloy of tungsten and metal oxides. These electrodes have been specially designed for use in conjunction with Lampert fine welding equipment. The electrodes have […]
What are possible causes of black welds?
The protective gas flow rate is set too high:Make sure that the flow rate is set correctly. 2 – 3 liters/min are completely sufficient (this corresponds to approximately 0.4 bar)! […]
How do I set the flow regulator correctly?
To adjust the flow rate, turn on your PUK and carefully open the valve of the gas cylinder. On the PUK 3, press the power control on the device; on […]

Can solder be used as a substitute for welding?
Solder tends to burn during welding due to its additives, so it is not suitable as a filler metal. Also, if possible, do not weld at solder joints, or alternatively, […]
Welding silver: what to consider?
Metals with high thermal conductivity are generally difficult to weld, but: The thermal conductivity of silver decreases as its temperature increases. This means that silver can be welded better when […]
When to solder, when to weld?
In principle, soldering – where usefully applicable – is usually considered the ideal joining technique in jewelry manufacturing. Nevertheless, there are a variety of applications in jewelry making and repair […]
How does the spot weld change when you change the time?
The pulse time is mainly responsible for the penetration depth of the spot weld. The longer – the deeper. For very thin material, always work with the shortest possible pulse […]
How do the spot welds change when you change the power?
In general, it can be said that the power controls the diameter of the spot weld. Although higher energy also increases the penetration depth of the weld puck, the welds […]
Up to what sheet thickness can workpieces be welded? Max. Penetration depth
If the material thickness of the workpiece at the fracture point is greater than 1.0 mm, the penetration depth of the welding device is not sufficient. The fracture must then […]
What is the time interval between two welding spots?
The time between two welds is 0.8 to 2.0 seconds. It automatically adjusts to the operator’s working speed. I.e. with a fast welding sequence, the time span is automatically reduced […]
Is argon toxic?
It is a noble gas and a natural component of air. Like all noble gases, it does not react: it cannot burn and is not toxic. Nevertheless, care should be […]
How long does a 10 liter argon bottle last?
In an average goldsmith’s workshop, one filling of a 10-liter bottle will last for about 6 to 12 months, depending on how intensively welding is done with the PUK.
How strong is the heat generation when welding with Lampert welding equipment?
The heat generated during welding is very low. Especially on heat-sensitive areas such as gemstones, it is recommended to work with the shortest possible pulse time (our PUK already have […]
Can different metals or alloys be welded together?
Yes – Even metals with very different properties can be welded, e.g. gold with titanium. However, if the physical differences are too great, as is the case with titanium and […]
Can you weld aluminum?
Yes, you can weld aluminum. A special aluminum mode is stored in the current Micro Arc Welder. With this mode, aluminum alloys suitable for welding can be welded particularly well […]
Can brass be welded?
In the current model a brass mode is stored, with this brass alloys with low zinc content can be welded well.
Which metals can be welded?
Basically, all precious metals and precious metal alloys of gold, silver, platinum and palladium can be welded. In addition, all metals can be welded that are also weldable by laser […]
Wie erlerne ich das PUK- oder MAW-Schweißen?
The technique of welding with Lampert welding equipment is easy to learn. Nevertheless, you should take a few hours to familiarize yourself with the device. The PUK, which is included […]
What does it matter what angle the electrode has to the workpiece?
The angle plays an extraordinarily significant role. The highest penetration depth is achieved at a 90° angle to the workpiece. When the electrode is placed at an angle, the metal […]
Are there any maintenance or servicing costs?
Maintenance is not necessary! In normal operation, only minor costs are incurred for shielding gas and due to wear of the electrode.
The microscope is equipped with an electronically controlled, DIN-certified eye protection filter. This ensures triple protection of the eyes: permanent protection against glare from UV and IR light and electronically […]
What does “welding” mean?
Workpieces are selectively melted and thus joined together. Ideally, filler metal always has the same melting temperature as the workpiece itself (in brazing, a brazing alloy is always used which […]
