„PUK 3 professional“ offers beside the proven functions of the basic units, more achievement and a number of additional possibilities.
Impulse Mode:
Softspot (Standard-Mode)
This welding impulse (impulse shape) is characterised by "soft" welding behavior and is recommended for most applications.
Micro (Micro-Mode)
This setting makes precise welds possible at very thin materials. This particularly fine output gradation, as well as a special pulse shape in the micro mode, is suitable particularly for material thicknesses as thin for 0,10 mm for sheet material as for 0,25 mm wires!!!
Gap (Joint-Mode)
This pulse shape is recommended for applications, in which it is essential to weld in deep joints or angles.
The Gapspot (joint mode) is also very well suitable for silver. With this pulse shape even normally difficult weldable silver alloys can be welded with success
The finer adjustment possibilities of pulse time and power make an exact tuning of spot weld, size and penetration depth possible. Softly and electrodes sparing welds, in the standard impulse as well as a special joint impulse for welds in angles and recesses always guarantee better results.
Using the PUK – fine welding devices opens many possibilities of fine welding applications. Welding on fittings, adding material, welding a loop, joining items prior to soldering, fixing porosity, and preparation of seams are just a few of the many examples of work which is now possible.
Metal can be added easily especially where material is missing for example on fracture lines or where the profile of the work piece needs to be built up.
All precious metals and precious metal alloys, high-grade steel and titanium, as well as many tin alloys (costume jewelry) are particularly suitable for welding.
Principally it applies that all metals, which are suitable for arc welding can be welded with the PUK.
The operating speed has doubled by using more efficient main power transformers and by adapting the speed of the gas flow.
