3 Alignment/measurement
•
Applying slight pressure, press the welding torch with the collet against a clean, purged location on the
workpiece and then press the torch trigger for approx. 2 seconds. A short-circuit current will flow
briefly, which is used to determine and display the cable resistance. The value can be between 0 mΩ
and 60 mΩ. The new value is immediately saved without requiring further confirmation. If no value is
shown on the right-hand display, then measurement failed. The measurement must be repeated.
4 Restoring welding standby mode
•
Switch off the welding machine.
•
Lock the tungsten electrode in the collet again.
•
Screw the gas nozzle onto the welding torch.
•
Switch on the welding machine.

Welding task selection
It is only possible to change the basic parameters when no welding current is flowing and any
possible access control is disabled > see 5.4 chapter.
The following welding task selection is an example of use. In general, the selection process always has
the same sequence. Signal lights (LED) will show the selected combination.
