ary support so cylinder cannot fall

and break off valve.

1 Cylinder

2 Regulator/Flowmeter

Install so face is vertical.

3 Gas Hose Connection

Fitting has 5/8-18 right-hand

threads. Obtain and install gas

hose.

4 Gas In Fitting

5 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

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 TIG

Gas flow starts when tungsten

touches work (touch sensed).

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).
