TIG spotArc
NOTE
The settings for the individual parameters are made on the welding machine. The
procedure is described in the operating instructions for the respective welding machine.
Figure 5-3
Sequence:
• Press and hold torch trigger 1.
• The gas pre-flow time elapses.
• HF ignition pulses jump from the electrode to the workpiece, the arc ignites.
• The welding current flows and immediately assumes the value set for the ignition current I
start
.
• HF is switched off.
• The welding current increases in the adjusted up-slope time to the main current AMP.
NOTE
The process ends when the set spotArc time elapses or if the torch trigger is released
prematurely.
