As an example the process is shown with HF ignition. Arc ignition with lift arc is also possible,
however

.
Selecting the process activation type for the welding process
> see 4.7 chapter
.
Up-slope and down-slope times possible for long spot time setting range (0.01
–20.0 sec) only.
Press and release torch trigger (tap) to activate the welding process.
Touch the torch gas nozzle and tungsten electrode tip carefully against the workpiece.
Incline the welding torch over the torch gas nozzle until there is a gap of approx. 2
–3 mm between the
electrode tip and the workpiece. Shielding gas flows during the set gas pre-flow time
. The arc
ignites and the previously set ignition current
flows.
The main current phase
ends when the set spotArc time
elapses.
The welding current decreases to the end current level within the set down-slope time
.
The gas post-flow time
elapses and the welding process ends.
Press and release the torch trigger (tap) to reactivate the welding process (only for separate
process activation). Touching the welding torch with the tungsten electrode tip again against the
workpiece will initiate the next welding processes.
