ENGLISH
When the trigger is pressed and released immediately, the system returns to the welding current.
3. Press (3T) trigger and keep it pressed to start the weld completion procedure.
Gas flow continues until the torch trigger is released.
4. Release (4T) torch trigger to start the post gas procedure (adjustable time).
12.5 2T - 3 LEVEL MIG/MAG WELDING
1. Bring the torch up to the workpiece.
2. Press (1T) torch trigger.
The wire advances at the approach speed until making contact with the material. If the arc does
not strike after 10 cm wire protrusion, wire feeding is locked and the welding unit outputs are de-
energized.
The welding arc strikes and the wire feed rate changes to the first welding level (hot start), 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.
The hot start level continues for the start time, which is settable in seconds; then switch to normal
welding speed is performed in accordance with the start slope, which can be set in seconds.
3. Release (2 T) the torch trigger to switch to the third welding level (crater filler), which is set as a
percentage of the normal welding feed rate.
The switch of welding current level in terms of crater filling is performed in accordance with the
crater slope, which can be set in seconds.
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.
4. The crater filler level continues for the crater time, which is settable in seconds; at the end of this
time welding is interrupted and the post gas stage is performed.
12.6 2T SPOT - 3 LEVEL MIG/MAG WELDING
The welding process is the same as the 2T - 3 LEVELS process, except that the welding procedure
continues, at the preset current, for the time set with the spot time parameter.
The weld is closed in the same way as with the 2T - 3 LEVELS process.
12.7 4T - 3 LEVEL MIG/MAG WELDING
1. Bring the torch up to the workpiece.
2. Press (1T) torch trigger.
The wire advances at the approach speed until making contact with the material. If the arc does
not strike after 10 cm wire protrusion, wire feeding is locked and the welding unit outputs are de-
energized.
The welding arc strikes and the wire feed rate changes to the first welding level (hot start), 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.
3. Release (2T) trigger to switch to normal welding speed; then switch to normal welding speed is
performed in accordance with the start ramp, which can be set in seconds.
4. Press the torch trigger again (Level 3) to switch to the third welding level (crater filler), which is set
as a percentage of the normal welding feed rate.
The switch of welding current level in terms of crater filling is performed in accordance with the
crater slope, which can be set in seconds.
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.
