Welding wires for gold alloys
All welding wires for gold and platinum alloys consist of standard jewellery alloy with the requisite degree of fineness. For typical applications in jewellery production and repair, the welding wires must be processed such that these are very thin, in order that the wires can be metered and applied with low power.

Welding wire for platinum
When welding Pt alloys, in particular with cast platinum, small pores and/or brittleness can arise if welding repeatedly takes place in the same place. This can be avoided in general terms through the application of fresh metal with welding wire. When welding on platinum, a clean welding area and optimum shielding gas coverage are very important.

Welding wire for tin
The welding wire from pewter 99.9% is suitable for repairs on objects from tin and tin alloys. The high purity of the wire guarantees a very ductile and therefore stable and clean weld. It is advisable to process the welding wire with an increased gas flow and larger gas nozzle (art. no. 100 150-4).

Welding wire for repairs and alloys that are difficult to weld
This Pd/Ag/Cu welding wire with a high portion of palladium is particularly well-suited for repair welds on alloys that are only weldable to a limited degree with themselves or with each other. The welding wire stands out due to its excellent adhesion properties and exceptional toughness. It is therefore frequently used as a "bridging metal" between awkward alloys (colour grey).

- Welding wire ALSI for connections and application on aluminium-silicon alloys up to 12 % Si, and for different types of aluminium alloys together.
ATTENTION - cleanliness is the most important preparation for welding:
- It is very important that the welding area is carefully cleaned for successful welding. Dirt, oxides, oil or wax layers make good welding results impossible.
- The welding points must be metallically clean. Depending on the contamination, chemical cleaning products or machining processes are highly suited for cleaning the welding areas. With minor soiling and adhesions it is also advisable to clean with an ultrasonic device.

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.

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.
Michael Berger
Goldsmith and KineticDüsseldorf
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.
