The new PUK 6.1 - finest precision welding technology for jewelry manufacturers
The PUK 6.1 is the logical further development of the globally successful PUK 6 and benefits from 24 years of experience and expertise in the development of welding equipment for jewelry manufacturers, goldsmiths, silversmiths, jewelers, watchmakers and many more.
The PUK 6.1 not only offers a faster welding spot sequence, the speed can now also be set continuously. In addition, up to 5 individual configurations can be saved permanently and the PUK 6.1 starts automatically with the last selected settings. Also, the PUK 6.1 has a new PIN mode on board for welding pins.
Computer-aided simulations and numerous welding tests have once again noticeably improved the precision, homogeneity and appearance of the precious metal welding spots compared to the PUK 6. This takes the fine welding technology of the PUK 6.1 to an uprecedented new level.
The PUK 6.1 easily handles material thicknesses of less than 0.2 mm and, in addition to welding all precious metal alloys for fittings, studs, eyelets, chain links, rings etc., now also enables simple welding of ear studs and pins.
