Fine Welding with PUK 4.1

The PUK precision welding device is a compact and versatile TIG impulse welder with which fine and minute welds can be carried out under a welding microscope.
The operating principles and spectrum of possible applications are very close to those of laser welding. This similarity means that the exact positioning of small, stable spot-welds or welds in hard-to-get-to or deep lying positions poses no problem.
In contrast to soldering, the area of the work piece that is affected by heat is very small when working with the “PUK”. So small in fact, that problem free welds adjacent to precious stones or pearls can be handled with ease.
Even the finest of welds are possible. Utilising our welding microscope, the problem free handling of pieces of work right down to 0,2 mm now becomes a reality.
The PUK 4.1 precision welding equipment puts a whole host of possible applications in the 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 are only a few further examples of the PUK’s versatility.
All metals or alloys which can be TIG or Laser welded, are suitable for use with the PUK. In addition to many precious metal alloys, many non-ferrous metals (e.g. copper and tin alloys, many steels, titanium and aluminium alloys, etc.).
Using the additional function “tack welding”, workpieces made of suitable metals can be temporarily attached to each other.
