PUK 6 from Lampert - the jewelry welder
A comparison with its predecessors shows: 20 years of experience and passion in the development of jewelry welders have raised the features of the PUK 6 to an unprecedented level.
The PUK 6 is THE jewelry welder for every jewelry manufacturer, goldsmith, silversmith, watchmaker, jeweler and many more.
Welding on fittings, applying and repairing metal to edges and surfaces on jewelry and watches, fixing work, welding eyelets, closing pores, producing seams and much more is possible with the PUK 6. The PUK 6 also handles the welding of precious metals including silver, copper, bronze and all other weldable alloys as well as material thicknesses of less than 0.2 mm with ease.
The facts of the PUK 6 jewelry welders at a glance

- Noble, selected materials for highest demands on value and appearance
- Up to 3.3 spot 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
- The new PUK 6 jewelry welders can produce 50% finer spot welds in the lower power spectrum.
- Minimum pulse duration now down to 0.1 ms: 67% shorter impulse duration in micro mode
- 20% faster and thus more agile electrode lifting
- 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 ambient conditions – real added value in the workshop for every goldsmith and silversmith
- Faster operation and material selection (gold, silver, platinum, palladium, copper alloys, titanium and more) through direct control with one-hand joystick with turn-push-tilt function
- Faster maximum spot weld sequence due to extended speed function – selectable in 3 levels
- Refined micro mode with tighter gradation enables extended spectrum when welding at the lower power limit
- New standby mode: Continuous availability with 85% lower energy consumption

- Optimized welding curves for all common precious metals and alloys in jewelry production, especially for all goldsmiths, silversmiths and watchmakers
- Very low, controllable heat generation, comparable to that of laser welding
- Higher maximum power and improved welding performance especially of highly conductive silver, copper and tin alloys due to the new speed function
- Compact size – fits into any jewelry manufacturer’s workshop
,
- Low acquisition costs
- Very good price-performance ratio
- Facilitates and saves time when repairing and soldering gold, silver and other precious metals
- Low costs for consumables
- Low consumption of argon
- Maintenance free technology
The jewelry welder in detail
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, 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 jewelry welder can also be used in the immediate vicinity of sensitive gemstones without causing damage, making it ideal for goldsmiths and silversmiths, but also for repair work by jewellers and watchmakers.
Compact and variable TIG impulse jewelry welder
The working method and range of applications are almost identical 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.
The Lampert technology will inspire you!
- Intuitive operation with virtually no learning curve, even for goldsmiths and silversmiths with little welding experience
- Intelligent presettings mean that only 2 operating steps are required. Select the metal group for the right precious metal and work situation > Let’s go!
