TORCH TRIGGER MODES
13.1
2T LIFT-ARC WELDING
1.
Touch the workpiece with the torch electrode.
2.
Press (1T) and keep the torch trigger pressed.
3.
Slowly lift the torch to strike the arc.
The welding current reaches the preset value, by way of a up slope time, if programmed.
4.
Release (2T) the 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.
13.2
2T HF WELDING
1.
Bring the torch up to the work until the electrode tip is approximately 2 or 3 mm away.
2.
Press (1T) and keep the torch trigger pressed.
The arc strikes without contact with the workpiece and the voltage discharges (HF) cease automatically.
The welding current reaches the preset value, by way of a up slope time, if programmed.
3.
Release (2T) the 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.

4T LIFT-ARC WELDING
1.
Touch the workpiece with the torch electrode.
2.

3.
Slowly lift the torch to strike the arc.
The welding current reaches the preset value, by way of a up slope time, if programmed.
4.
Press (3T) the 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).
5.
Release (4T) the trigger to extinguish the arc.
Gas delivery continues for the time set in the post gas parameter.
