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.
The process ends when the set SpotArc time elapses or if the torch trigger is released
prematurely.

The up-slope and down-slope times should be set to “0” to achieve an effective result.
