OUTPUT CONNECTIONS

WARNING

ELECTRIC SHOCK can kill.

•Keep the electrode holder, TIG torch and cables insulation in good condition and in place.

•Do not touch electrically live parts or electrode with skin or wet clothing.

•Insulate yourself from work and ground.

•Turn the power off pushbutton on the Square Wave TIG 355 “off” before connecting or disconnecting output cables or other equipment.

See Figure A.3 for the location of the work and elec- trode terminals, the gas and optional water solenoids, and the Remote Receptacle.

TIG TORCH CONNECTION

TIG welding torches come with 15 ft (4.6m) and 25 ft (7.6m) cables. Use the shorter length whenever pos- sible to minimize possible radio interference problems. With power source off, connect the torch cable to the “Electrode” terminal on the welder. Connect a sepa- rate work cable to the “Work” terminal of the welder. See Table A.3 for recommended work cable sizes. Both work and electrode cables should be routed through the cable strain relief holes provided in the base directly below the welding ouput terminals.

Connect the TIG torch gas and water fittings to the welder fittings. any torch with fittings that conform to Compressed Gas Association (CGA) standards can be used.

The welder fittings have the following threads: Gas

Inlet and Outlet: 5/8”-18 right-hand female; Water inlet

and Outlet: 5/8”-18 left-hand female. The cylinder of inert shielding gas must be equipped with a pressure regulator and flow meter. Install a hose between the flow meter and gas inlet on the welder.

WARNING

Observe the safety precautions necessary for handling and using compressed gas containers. Contact your supplier for specific information.
