TIG TORCH CONNECTION

The Twist-Mate connection allows fast and reliable TIG torch attachment to the electrode terminal of the Square Wave TIG 275 welding power supply. Twist- Mate TIG adapters are made of brass, combining high electrical conductivity with mechanical strength. They are available in several sizes and styles to accommo- date a wide selection of gas and water-cooled TIG torches.

•For Air-Cooled TIG Torch connections refer to TWIST-

MATE ADAPTER for LA-9 and LA-17 TIG TORCH section.

•For Water-Cooled TIG TORCH connections refer to

TWIST-MATE ADAPTER for LW-18 and LW-20 TIG TORCH Section.

Any torch having hoses and cables equipped with Compressed Gas Association (CGA) style fittings can be connected to an appropriate Twist-Mate adapter (see ACCESSORIES section). The power source must be switched off while making any of these connections.

Do not operate a water-cooled torch without an ade- quate coolant supply. Set-ups using recirculated coolant require that the cooler be switched on and run- ning. If the water solenoid valve option is used with a cooler, the coolant does not flow until the solenoid is actuated.

For set-ups using water as a single-pass through coolant, install a strainer into the system upstream of the Square Wave TIG 275 to reduce the concentration of particles that could contaminate the system. Otherwise, flow passages could become obstructed or clogged, causing torch overheating or failure. The optional water solenoid valve may also malfunction.

When the water solenoid valve option is installed into the Square Wave TIG 275, connect the coolant supply line from either cooler outlet or single-pass supply to the “Water Inlet” fitting located on the machine’s case front. Connect the TIG torch’s smaller water fitting to the “Water Out” fitting also located on the case front. A non-metallic coolant line is required between the elec- trode connection and the drain or cooler inlet. This reduces the possibility of an electrical hazard.

TIG welding torches are available with 12.5 and 25 foot cables (3.8m and 7.6m, respectively). Use the shorter length whenever possible to reduce radio interference problems.

WARNING

CYLINDER could explode if damaged.

•Keep cylinder upright and chained to a support.

•Keep cylinder away from areas where it could be damaged.

•Never allow the torch to touch the cylinder.

•Keep cylinder away from live electrical circuits.

•Maximum inlet pressure 150 psi.

The high-pressure cylinder of inert shielding gas must be equipped with a flow regulator that limits the gas pressure to 150 psi maximum at the machine’s gas inlet. This brass inlet fitting is located on the rear panel of the Square Wave TIG 275. Install a hose between the gas flow meter and the inlet fitting.

For other conditions, consult the manufacturer’s instructions for the water cooler or TIG torch being used.
