For all micro welding tasks in general industry applications such as electronics departments, R&D labs, aerospace industry, repair shops or in mobile applications directly at the customer‘s location when precision and consistency is a must, the PUK U5 General Industry is the answer! It can weld a multitude of materials such as Stainless Steel, Hastelloy, Invar, Inconel, Permalloy, MU-metals, Titanium, Copper, Platinum, Gold, Silver, and Aluminum with material thicknesses even as low as 0.2 mm. Users are able to achieve desired welding results without in-depth knowledge of metallurgy due to the PUK’s ease of use. One year manufacturer's warranty. Made in Germany.

The PUK Technique

Utilizing micro TIG technology, the PUK technique is based on the micro-impulse method, in which the arc is ignited electronically. The energy concentration acts under argon protective gas atmosphere with a special non-consumable tungsten electrode in the millisecond range concentrated on the welding spot. As soon as the electrode tip touches the workpiece, the welding process starts automatically. The argon gas forms a protective atmosphere above the welding spot to prevent oxidation. The specially tailored and shaped current pulse ignites the arc and creates a controlled melting of the metal - as frequently and precisely as desired.

Applications:

  • Perfect for fine welding of small components in a variety of metals.
  • Weld adjacent to heat-sensitive components.
  • Material mixes of different alloys are possible.
  • Can be used for permanent welds or simply tacking prior to further welding processes.
  • Can repair scratches or pits on components surfaces.
