Arc ignition
 Open the valve 19 on the TIG welding torch.
 Briey touch the workpiece with the tip of the elec-
trode at the point to be welded.
 Lift the electrode a little.
9 The arc burns between the workpiece and the elec-
trode.
Upslope
A short-circuit current of 60 A is used for igniting during
the TIG welding process. The upslope takes place with
115 A/s until the set welding current is reached.
