4 STROKE B-LEVEL 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) torch trigger.
○ The welding current reaches the preset value, by way of a up slope time, if programmed.
○ Press and immediately release the torch trigger to switch to the second welding current.
○ The trigger must not be pressed for more than 0.3 seconds; otherwise, the weld completion stage will start.
○ When the trigger is pressed and released immediately, the system returns to the welding current.
○ 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.

- 4 STROKE B-LEVEL:
○ 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 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.
○ Press and immediately release the torch trigger to switch to the second welding current.
○ The trigger must not be pressed for more than 0.3 seconds; otherwise, the weld completion stage
will start.
○ When the trigger is pressed and released immediately, the system returns to the welding current.
○ 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.
