2Regulator/Flowmeter Install so face is vertical.

3Gas Hose Connection

Fitting has 5/8-18 right-hand threads. Obtain and install gas hose.

4Gas In Fitting

5Gas 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).
