TIG arc ignition
5.4.4.1 Liftarc
Figure 5-60
The arc is ignited on contact with the workpiece:
a) Carefully place the torch gas nozzle and tungsten electrode tip onto the workpiece and press the torch
trigger (liftarc current flowing, regardless of the main current set).
b) Incline the torch over the torch gas nozzle to produce a gap of approx. 2-3 mm between the electrode
tip and the workpiece. The arc ignites and the welding current is increased, depending on the
operating mode set, to the ignition or main current set.
c) Lift off the torch and swivel to the normal position.
Ending the welding process: Release or press the torch trigger depending on the operating mode
selected.
