Variation of operation mode spotArc, ignition with workpiece contact
• on = on
• off = off (factory setting)
Short spot time
Setting of 5–-999 ms (1-ms steps)
Setting process activation
• on = Separate process activation:
The welding process has to be reactivated for every arc ignition by pressing the torch
trigger.
• off = Permanent process activation:
The welding process is activated by pressing the torch trigger once. The following arc
ignitions are initiated by shortly touching the tungsten electrode against the
workpiece.
