Sequence
1st cycle:
• Press torch trigger 1 and hold down.
• Gas pre-flow time
• HF ignition pulses jump from the electrode to the workpiece. The arc ignites.
• The welding current flows and immediately assumes the value of the start current
• HF switches off.
• The welding current ramps up to the main current
If torch trigger 2 is pressed together with torch trigger 1 during the main current phase, the welding cur-
rent decreases to the secondary current
If torch trigger 2 is released, the welding current increases again to the main current AMP in the set slope
time . The parameters
2nd cycle:
• Release torch trigger 1.
• The main current falls to the end-crater current
If the 1st torch trigger is pressed during the down-slope time,
the welding current returns to the set main current AMP
• Main current reaches the end-crater current
• Set gas post-flow time
When the foot-operated remote control is connected, the machine switches automatically to non-
latched operation. The up- and down-slopes are switched off.
