○ 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 part and the voltage discharges (HF) cease automatically,
the welding current will assume the pilot current value. (if activated from the SET UP menu.)
○ Release (2T) 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) the trigger to extinguish the arc.
○ Gas delivery continues for the time set in the post gas parameter.
