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.

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.
Sceptical? Drop by my workshop and see for yourself.
I made first experience with a PUK back in 2003 in State Drawing Academy Hanau. It was the PUK111 and I instantly fell in love with it.
With PUK’s help I can realize any of my ideas. It makes welding of different metals and combining them with different materials a lot easier. Especially since I often use very thin metal sheets and wires, the PUK is the perfect tool for me.
I had different PUK models in my workshop already – the PUK 3s, PUK 04 and now the PUK5 – and every new model has offered an increased accuracy and improved welding results.
That is why the PUK has become one of the most important pieces of equipment in my workshop.
I must say that nowadays working without PUK is unthinkable for me!
You may take anything but my PUK from me!!!
I use it for everything made of gold, silver, steel, titanium and platinum.
I work easily on claws without having to remove the stones before.
The PUK is perfect for fixing the parts prior to soldering, for different micro repairs and also allows me to work on watches (crowns, shafts, gears and bracelets).
My PUK is a PUK3s professional plus and since I bought it, it paid for itself within the first six months already.
I think every goldsmith workshop needs a PUK to speed up the jewellery repairs and production.
Doing jewellery repairs, the ability to add small areas of metal is vital and was missing for the first 25 years of my time as a jeweller.
Then I heard about the welders that were becoming available so I bought a Lampert PUK3S and several years later I am still using it for most of the repairs that I do.
It paid for itself in the first year because it saves me so much time.
It opens up new possibilities such as repairing bracelets without having to refinish them all over, retipping stones like emeralds without removing them, tacking things together before soldering, repairing porosity etc. In most cases it's faster and cleaner than soldering.
I regard it as an essential tool for manufacturing and repairing jewellery and can't imagine working without it.
I have been a goldsmith for 10 years now.
I was taught the old fashion way by a master craftsman from the Birmingham jewellery quarter
Now with this fantastic new PUK I have moved away from using a naked flame and I mainly use my PUK for most of my repairs, its faster, cleaner and when working on some delicate stones such as opal or emerald, the repair is always safe.
It has also saved me so much more time allowing me to do more work in a day improving productivity.
No goldsmith should be without one.
Orthodontic soldering is now a thing of the past. TIG welding is far superior in every way. The possibilities are endless with the PUK D2 TIG welder. Preparation is minimal and joins are stronger and smoother than soldering.
Since I have been using the PUK D2 I have not had any appliance breakages. Many jobs were not possible when I was limited to soldering. Now I can add small attachments to my appliances with little distortion from overheating. Intricate designs are easily and quickly added to any job with minimal preparation. Almost no finishing and polishing is needed saving much time and money. Working under the microscope makes welding much more precise.
Not only is this PUK D2 excellent, the Lampert ambassadors are also very helpful. I had many conversations with them and they were more than happy to help. They always urged me to keep in touch as they want everyone to appreciate this machine as much as they do.
"You know how some of your best ideas border on the actual doable technology? As a multidisciplinary artist, my various visions often look beyond that technical border. In many cases I must invent the tools necessary, and pursue with considerable improvisation and limitations over years. In 2013, I wanted to make artworks of pre-polished stainless steel that would be very difficult to polish after normal TIG welding due to narrow access angles.
The amazingly different PUK solution: I was very surprised and delighted to find out about the PUK, and was treated to an unusually terrific demo of it in my studio. This is a machine I could never have ‘invented’, or even imagined! And it not only solved many of the problems for the specific artworks in mind, it opened the door to many new ideas that are now possible!
And not to be overlooked: the PUK is made in Germany to highest standards, and the support can’t be beat! Lampert has proven to me to be an innovative company that cares about quality, but also knows that what they are producing, solves problems and opens your creativity."
