PUK 6 from Lampert - the jewelry welder

A comparison with its predecessors, our jewelry welders, shows that 20 years of experience and passion in the development of precision welding machines have raised the properties of the PUK 6 to an unprecedented level.

The tool for every goldsmith or silversmith, for jewelers, watchmakers and many other …

Welding veneers, applying metal to edges and surfaces on jewelry and watches, similar to laser welding, fixing work, welding eyelets, sealing pores, making seams, welding precious metals including. silver as well as copper and bronze and all weldable alloys. The new jewelry welder PUK 6 can handle material thicknesses even below 0.2 mm.

All around the jewelry welder PUK 6

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

When the electrode tip of the welding handpiece touches the workpiece, the Welding process automatic. 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, this jewelry welder can also be used to weld many non-ferrous metals such as copper and tin alloys, as well as many steels, stainless steel and titanium alloys. You can see some examples in the application examples for the jewelry welder.

All alloys suitable for laser welding can also be welded with the PUK 6. The welding machine is particularly characterized by the fact that it can also weld in the immediate vicinity of sensitive gemstones without causing damage, making it ideal for goldsmiths and silversmiths.

Compact and variable TIG impulse jewelry welder

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 precision welder opens up a wide range of applications in jewelry production: Constructions made from sheet metal or wire elements, fixation welds and repairs, filling defects, filling pores by applying welding wire, and much more can be realized with the PUK 6 – from the smallest repair to series production to the most extraordinary new creation.
