Gas Out Fitting
The Gas In and Gas Out fittings
have 5/8-18 right-hand threads.
Obtain proper size, type, and length
hose and make connections as fol-
lows:
Connect hose from shielding gas
supply regulator/flowmeter to Gas
In fitting.
Connect hose coupler to torch.
Connect one end of gas hose to
hose coupler. Connect remaining

Operation
The gas solenoid controls gas flow
during the TIG process as follows:
Remote TIG
Gas flow starts with remote contac-
tor on.
Gas flow stops at end of post−flow
if current was detected, or with re-
mote contactor off if no current was
detected.
Lift−Arc Trigger Hold TIG
Gas flow starts when output switch
is depressed.
Gas flow stops at end of post−flow.
Scratch Start TIG
Gas flow starts when current is de-
tected.
Gas flow stops at end of post−flow.
Post−flow time is factory set to 5
seconds per 100 amps of weld cur-
rent. The minimum post−flow time
is 5 seconds. The maximum post−
flow is 20 seconds (post flow set-
tings are not adjustable by the end
user).
