Fig. 5c Functional sequence in special 4-step mode - Variant IV
Variant V (Fig. 5d) allows the welder to raise and lower the welding
current without an Up/Down torch.
The longer the torch-trigger rocker switch is pushed forward during
welding, the more the welding current is increased (up to maxi-
mum).
After the welder releases the torch trigger, the welding current
remains constant. The longer the torch trigger is pushed forward
once again, the further the welding current is reduced.

LED INDICATOR FOR 2-STEP MODE
2-step mode (Fig.6)
- is activated from TIG torch trigger
- is mainly used for tack welding
- In the "PRESETTINGS LEVEL ---" program-level, parame-
ter TIG, the setting for StS must be set to "OFF"
Functional sequence:
1. Pull back and hold the torch trigger
- Gas pre-flow time elapses
- Arc ignites at the pre-set value for start-arc current I
ignition: HF cuts out automatically after ignition)
t
- After ignition, the welding current rises via the internally pre-
set upslope to the welding-current value I
- LED lights up
2. Release the torch trigger
- Arc goes out (with or without the current being lowered)
- Internally pre-set gas post-flow time elapses
When the remote-control pedal unit TR 52mc is used, the
machine automatically switches over to 2-step mode.
