13 TORCH TRIGGER MODES
13.1 2T MIG/MAG WELDING
1. Bring the torch up to the workpiece.
2. Press (1T) and keep the torch trigger pressed.
The wire advances at the approach speed until making contact with the work.
3. The arc strikes and the wire feeder accelerates to the set feed rate value.
4. Release (2T) the trigger to start the weld completion procedure.
Gas flow continues for the time set in the post gas parameter (adjustable time).
13.2 4T MIG/MAG WELDING
1. Bring the torch up to the workpiece.
2. Press (1T) and release (2T) the torch trigger.
The wire advances at the approach speed until making contact with the work.
3. The arc strikes and the wire feeder accelerates to the set feed rate value.
4. Press (3T) the trigger to start the weld completion procedure.
Gas flow continues until the torch trigger is released.
5. Release (4T) the torch trigger to start the post gas procedure (adjustable time).
13.3 3 LEVEL MIG/MAG WELDING
1. Bring the torch up to the workpiece.
2. Press (Level 1) the torch trigger.
The wire advances at the approach speed until making contact with the work.
3. The welding arc strikes and the wire feed rate changes to the first welding level, which is set as a percentage of the normal welding feed rate.
This first level is used to create the weld pool: for example, when welding aluminium a value of 130% is recommended.
4. Release (Level 2) the torch trigger to switch to the normal welding feed rate.
5. Press the torch trigger again (Level 3) to switch to the third welding level, which is set as a percentage of the normal welding feed rate.
This third level is used to complete the weld and fill the final crater (crater filler) in the weld pool: for example, when welding aluminium a
value of 80% is recommended.
6. Release the torch trigger a second time to close the weld and run the post gas procedure.
