The new PUK masters the welding of accessories, applying metal, fastening work, welding eyelets, sealing pores, generating seams, welding precious metals incl. silver as well as copper and bronze and all alloys suitable for welding, even material thicknesses of less than 0.2 mm.
that is very close to laser welding in terms of working method and range of applications. On workpieces with a thickness of 0.2 mm or greater, it is an effortless process to produce robust welds.
The PUK 5.1 precision welding equipment puts a whole host of possible applications for jewellery production at your fingertips. Structures made from sheet or wire elements can be just as easily done as tack welds and repairs to jewellery parts, restoring missing parts or filling of pores by applying welding wire - and many more options, the PUK 5.1 is able to produce anything from the smallest of repairs to volume production, and even the most extraordinary of new creations.
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 with a diameter of between 0.3 and 3.0 mm takes place (depending on material and setting).
In addition to many precious metal alloys such as gold, silver and platinum, many non-ferrous metals such as copper and tin alloys, many steels, titanium and aluminium alloys are suitable for welding. All alloys suitable for laser or TIG welding can also be welded with the PUK 5.1.
Facts that speak for themselves:
The operating concept of the PUK 5.1 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.
Individual device set-up using the settings menu, e.g. preselection of welding cycle, calling operating levels up on screen and hiding them again, e.g. program memory, expert level, tack welding ...
Extremely simple touchscreen operation. Now with slide function!
Preselection of two different welding cycles
The application range of the PUK 5.1 is further expanded with material thickness down to less than 0.2 mm allowing the welding of wires and sheets with even greater control.
Shorter repetition rates and serial pulses enable a continuous workflow. With this setting, the PUK offers the opportunity to shape the added material as desired and to significantly improve the welding characteristics of highly thermally conductive materials such as silver, copper and bronze.
NEW: EXPANDED SELECTION OF METALS
Optimised welding parameters for copper and bronze. The PUK takes over full control despite the high thermal conductivity.

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.
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 spots in order to achieve invisible connections emerged the subversive intention to handle the connection spots as obviously as possible. A design idea came into existence that turns the welding spots into my main design feature and orchestrates them like little diamonds. I see that precision technology like Lampert’s spot welding device can - aside from the regular range of applications - produce a high aesthetic value. I want my jewelry to reflect that.
The PUK offers clean connections, precise working, new possibilities. It doesn’t just simplify, it paves new ways for jewelry design.
My expectations for the PUK U5+ were very high and were met all along the line. Working with the PUK U5+ is very simple and uncomplicated.
An artist carefully compiles his tools because he uses them to express his thoughts and ideas through his hands. The high expectations of yourself must also be placed on the tools. That is why I only work with professional tools and machines.
For the production of my kinetic solar sculptures I prefer to use round steel rods up to 4 mm and sheets up to 1 mm thick. In the past years I have tried many techniques to optimally combine these materials. I have already used some processes, such as TIG welding, brazing with hydrogen, spot welding or 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 never seen before. The first-class technical support from the Lampert company was able to advise me "on point" what the possibilities of the PUK U5+ are.
My expectations for the PUK U5+ were very high. But these were met all along the line. Working with the PUK U5+ is very simple and uncomplicated. It feels like holding a thick pencil in your hand, easy to handle, safe and accurate.
I usually only rave about Swiss made machines. But I with pleasure took the PUK U5+ from Lampert, made in Germany, in my train of machines.
Working with PUK 2 since 2006.
My favorite cocktail is; PUK, argon and titanium.
If I didn't have the PUK I wouldn't have been able to make some of my best titanium pieces.
I bought my PUK2 in 2006, right at the time I opened my own workshop: www.josemarin.net.
At first, I used it in the creation of gold and platinum jewellery and in these three directions:
At present it is my great help for the creation of my pieces of titanium and Timascus, so far I have managed to do everything I set out to do.
I must admit that my PUK2 is a very old version, with limitations for silver and bronze, but otherwise it is a perfect machine and very resistant, in 14 years I have not had any breakdowns.
As my brother and me started our own business, the PUK 5 was our first purchase along with two workbenches. We both had very good experience with the PUK 2 and PUK 04 and therefore knew that this wonderful device would become indispensable for us.
The PUK can be summarized 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 welder every day and the results are impressive and yet we have the feeling that we have not yet exhausted the "PUK potential".
With the PUK I brought building custom made radio-controlled construction models to the next level!
I am a perfectionist and I try to build my radio-controlled construction models to the highest quality and detail. I was looking for a device that can actually allow me to achieve this goal. Previously I was not able to work with steel or stainless steel, and because of the fine detail and precision work I was not able to weld with a normal TIG welder. I was recommended by a mate of mine who saw a demonstration of the PUK welder at an expo. I contacted LAMPERT, explained situation and they advised me the exact equipment I needed. Early 2017 I purchased the M200 which was shipped to Australia. LAMPERT guided me in the initial stages via Skype support how to use the machine. This was very clear and now after almost 3 years of use I cannot do without it. The amount of precision and welding size exactly replicates the scale and strength needed for my models. I am now able to work with various materials and stainless steel is my favorite. I highly recommend this machine to any serious and professional model builder.
Since 2002 we are still using Lampert’s excellent primary model of fine welding devices (PUK 111) in our local jewellery manufacturing by at least 10 professional goldsmiths on a daily basis.
Lampert PUK a must for every Jeweller
I invested in a PUK 5 welder and was able to obtain a pay back within 6 Months. The PUK enables me to do additional repair and restoration of jewellery over traditional flame soldering methods through less heat dispersion, pinpoint control and seamless joints. I selected the PUK 5 over other welders for its quality, support service, no maintenance requirements and end welding results.
I have used various models of the PUK over the past 15 years and currently have a PUK5 at my bench. I have yet to find a more versatile machine for a jeweller’s workshop. Only imagination limits application where the PUK is involved. Whether its mounting, repair work, stone setting, engraving, or otherwise, the PUK proves itself invaluable – no matter the metal or alloy.
