○ Bring the torch up to the work until the electrode tip is approximately 2 or 3 mm away.
○ Press (1T) and keep the torch trigger pressed.
○ The arc strikes without contact with the workpiece and the voltage discharges (HF) cease auto -
matically.
○ The welding current reaches the preset value, by way of a up slope time, if programmed.
○ Release (2T) trigger to start the weld completion procedure.
○ The current reaches the end current value in the time set in the down slope time parameter.
○ The arc is extinguished.
○ Gas delivery continues for the time set in the post gas parameter.

- 4 STROKE LIFT:
○ Touch the workpiece with the torch electrode.
○ Press (1T) and keep the torch trigger pressed.
○ Slowly lift the torch to strike the arc.
○ The arc strikes, the welding current assumes the pilot current value. (if activated from the SET
UP menu.)
○ Release (2T) the torch trigger.
○ The welding current reaches the preset value, by way of a up slope time, if programmed.
○ Press (3T) trigger and keep it pressed to start the weld completion procedure.
○ The current reaches the end current value in the time set in the down slope time parameter.
○ The arc continues and the current output will be the value set in the end current parameter.
○ In these conditions the weld pool can be closed (crater filler current).
○ Release (4T) trigger to extinguish the arc.
○ Gas delivery continues for the time set in the post gas parameter.
