Sequence:<br />
• Press and hold torch trigger 1.<br />
• The gas pre-flow time elapses.<br />
• HF ignition pulses jump from the electrode to the workpiece, the arc ignites.<br />
• The welding current flows and immediately assumes the value set for the ignition current I start<br />
.<br />
• HF is switched off.<br />
• The welding current increases in the adjusted up-slope time to the main current AMP.<br />
NOTE<br />
The process ends when the set SpotArc time elapses or if the torch trigger is released<br />
prematurely.<br />
