Frequently Asked Questions (FAQ)

Our FAQ contains the most frequently asked questions about fine welding. We have answered them for you.

In an average goldsmith’s workshop, one filling of a 10-liter bottle will last for about 6 to 12 months, depending on how intensively welding is done with the PUK.

It is a noble gas and a natural component of air. Like all noble gases, it does not react: it cannot burn and is not toxic.

Nevertheless, care should be taken to ensure adequate ventilation in small rooms. You can also find out more about this topic from your gas dealer.

(Gas consumption is extremely low: a flow rate of 2 – 3 liters/minute is optimal. This corresponds to a pressure of only approx. 0.4 bar).

The time between two welds is 0.8 to 2.0 seconds. It automatically adjusts to the operator’s working speed. I.e. with a fast welding sequence, the time span is automatically reduced to 0.8 seconds.

If the material thickness of the workpiece at the fracture point is greater than 1.0 mm, the penetration depth of the welding device is not sufficient. The fracture must then be specially prepared for welding: The edges are filed in a V-shape and only the remaining material, which is now in direct contact, is welded together. The resulting joint is gradually filled with Zulege material (welding wire).
