1st cycle:

• Press torch trigger 1 and hold down.

• 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 of the ignition current

• HF

switches

off.

• The welding current ramps up to the main current

(AMP) in the selected up-slope time

If torch trigger 2 is pressed together with torch trigger 1 during the main current phase, the welding
current decreases to the secondary current

(AMP%).

If torch trigger 2 is released, the welding current increases again to the main current AMP.

cycle:

• Release torch trigger 1.

• The main current falls to the end-crater current

(minimum current) in the set down-slope time

If the 1

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

; the arc is extinguished.

• Set gas post-flow time

elapses.

When the foot-operated remote control RTF is connected, the machine switches automatically to
non-latched operation.
The up- and down-slopes are switched off.
