Designations on the reconnect panel LOW, MID, and HIGH correspond to the nameplated input voltages of a triple voltage welder. Dual voltage welders use only LOW and HIGH.

EXAMPLE: On a 208/230/460 volt welder, LOW is 208V, MID is 230V, and HIGH is 460V.

3.Make sure all connections are tight. Replace the case side and all screws.

WARNING

To avoid being startled by a high frequency shock, keep the TIG torch and cables in good condition.

------------------------------------------------------------------------

ELECTRIC SHOCK can kill.

Turn the power switch of the power source “OFF” before installing adapters on cable or when connecting or discon- necting adapter plugs to power source.

----------------------------------------------------------------------------

See Figure B.1 for the location of the work and elec- trode terminals, the gas and optional water solenoids, and the Remote Receptacle.The Square Wave TIG 275 is equipped with Twist-Mate connectors for the electrode and work connection.

WORK CABLE CONNECTION

The Twist-Mate connection allows fast and reliable work cable attachment to the work terminal of the Square Wave TIG 275 welding power supply.

Assemble the work cable by attaching the correct Twist-Mate adapter and work clamp to an adequately- sized welding cable. The Twist-Mate cable plug includ- ed with the machine is designed to accept a welding cable size of of #2 to #1. See Table A.1 and A.2 for rec- ommended sizes and corresponding hardware.

Assemble the correct Twist-Mate-adapter plug to the work cable as follows:

1.Skin the cable jacket to 1.00 in (25.4 mm) for a #2 thru 2/0 (35 thru 70 mm2) cable. Skin the cable jacket to 1.50 in (38.1 mm) for a 2/0 thru 3/0 (70 thru 95 mm2) cable.

2.If necessary, trim the cable end of the rubber boot to match the diameter of the cable.

3.Slide the rubber boot onto the skinned cable end. Use soap for lubricant if required.
