The NEW PUK 6 is here

Welding veneers, applying metal, fixing work, welding eyelets, closing pores, making seams, welding precious metals including. Silver as well as copper and bronze and all weldable alloys, material thicknesses also below 0.2 mm is handled by the new PUK.

The new PUK 6 - fine welding technology that sets standards

The comparison with its predecessors shows: 20 years of experience and passion in development raise fine welding technology to an unprecedented level with the PUK 6.

The facts at a glance
  • Up to 3.3 welds per second: up to 65% faster spot weld sequence
  • More homogeneous, smoother spot welds – excellent weld even with variable spot spacing
  • Higher heat input if required: Perfect results even with critical materials
  • 50 % finer spot welds in the lower power spectrum
  • Minimum pulse duration now down to 0.1 ms: 67% shorter welding time in micro mode
Handpiece and electrode
  • 20% faster and thus more agile electrode stroke
  • Maximum electrode thickness now up to 1 mm
  • Up to 50 % longer service life of the electrode
    Average measured service life improvement in test setups, actual value depends on individual user profile
  • 70% higher display resolution with increased viewing angle under all environmental conditions
  • Faster operation and material selection through direct control with a central operating element
  • New standby mode: Continuous availability with 85% lower energy consumption

Compact and variable TIG impulse 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 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 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 and platinum, many non-ferrous metals such as copper and tin alloys, many steels, titanium and aluminum alloys are also suitable for welding.

All alloys suitable for laser or TIG welding can also be welded with the PUK 6.

Video presentation of the new PUK 6

See here a short presentation of the new PUK 6 by the goldsmith Christoph Straube from Nuremberg. He will clearly explain the advantages and innovations of the new generation of devices – let him surprise you!

The PUK technology will inspire you!
  • The intuitive operation
  • Intelligent presettings mean that only 2 operating steps are required. Select metal group and work situation > Welding!
  • 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.
  • 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.

High quality connectors and professional screw and plug-in connections ensure durability and lasting safety in daily use.
