Around the PUK 6

The functional principle of PUK welding is as simple as it is ingenious

If the electrode tip of the welding handpiece touches the workpiece, the welding process starts automatically. At the point of contact, a melting of 0.3 to 3.0 mm diameter occurs under inert gas atmosphere (depending on material and setting).

In addition to precious metal alloys such as gold, silver, platinum and palladium, many non-ferrous metals such as copper and tin alloys as well as many steels, and titanium alloys are also suitable for welding with the PUK 6.

All alloys suitable for laser welding can also be welded with the PUK 6. The PUK 6 is particularly characterized by the fact that welding can be carried out without damage even in the immediate vicinity of sensitive gemstones.

Compact and variable TIG impulse welder in the jewelry manufacturing industry

in which the mode of operation and range of applications are very close to laser welding. Stable welds can be made easily on workpieces as thin as 0.2 mm.

The PUK 6 fine welding unit opens up a very large number of Possible applications in the production of jewelry: Constructions from sheet metal or wire elements, fixation welds and repairs, filling of defects, filling of pores by means of applying Welding rod, and much more can be realized with the PUK 6 – from the smallest repair to series production to the most unusual new creation.

The PUK technology will inspire you!
1. get started immediately even for beginners
  • Intuitive operation almost without familiarization
  • Intelligent presettings mean that only 2 operating steps are required. Select metal group and work situation > Welding!
2. quality guarantees precision
  • Precision handpiece for precision welding
  • Solid quality and the best materials such as stainless steel and Teflon are a prerequisite for precision in manufacturing and reliability in use.
3. fatigue-free ergonomics
  • The handling of the components: Well thought-out details facilitate handling.
  • Ergonomic working: Individual adjustment of the working position and comfortable hand rests for low-fatigue work.
