Selectable Features:
Feature 1 − Selectable Trigger Method (3 to choose from):
1 - Standard trigger − Typically used with a remote amperage con-
trol device. Standard trigger provides non-contact start in DC Im-
pulse TIG mode. It also enables Lift-Arc start, with a remote control,
in Lift- Arc mode.
2 - Lift-Arc Panel Control − Allows Lift-Arc start without using a
remote control device. Lift-Arc is used when HF starts are not per-
mitted, or to replace scratch starts.
3 - 2T Trigger Hold − In the HF mode, used with a push button con-
trol device as an on-off switch. In the Lift-Arc mode, using the Lift-Arc
method (see Section 4-3), push and release torch trigger to start
weld. Push and release torch trigger to end weld current and start
Auto Crater. Auto Crater ramps weld current down at a fixed rate to
end the weld cycle.
To change trigger method, enter set-up mode as described above
and illustrated on the next page.
