Obtain gas cylinder and chain to
running gear, wall, or other station-
ary support so cylinder cannot fall
and break off valve.

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
1
hose coupler. Connect remaining
end of gas hose to Gas Out fitting.
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).
