PUK 4c with SM03 and PUK flow regulator

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 workpiece 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. Utilizing our welding microscope, the problem-free handling of pieces of work right down to 0,2 mm now becomes a reality.

The PUK 4c precision welding equipment puts a whole host of possible applications in the jewelry production at your fingertips. Structures made from sheet or wire elements can be just as easily done as tack welds and repairs to jewelry 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 steel alloys, titanium and aluminum alloys, etc.). By using the welding microscope, high-quality welds can be readily produced, hence outstanding results and highest precision made possible. LED lighting, handpiece holder as well as an optimum working distance ensure comfortable work.

The eye-protecting filter integrated into the microscope is specially designed for welding applications. It gives the user‘s eyes a highly dependable safeguard whilst welding. By switching automatically from its clear setting (Luminescence DIN3) to its dark setting (Obscurity DIN11), glare from the electric arc is thus prevented.
