Optimising the ignition characteristics for pure tungsten electrodes
The best ignition and stabilisation of the arc (DC, AC) and optimum spherical cup formation in the
tungsten electrode depend on the electrode diameter being used.
The set value should correspond to the diameter of the tungsten electrode. The value can of course be
adjusted in line with different requirements.

Automatic cut-out
NOTE
The automatic cut-out function will be triggered by two conditions during the welding
process:
During the ignition phase (ignition fault)
• If there is no welding current within 3s after starting the welding.
During the welding phase (arc interruption)
• If the arc is interrupted for longer than 3s.
In both cases, the welding machine ends the ignition or welding process immediately.
