4. Hold the TIG adapter, with cables and hoses
installed, firmly in place by securing it into the Twist-
Mate receptacle on the power source or into a
padded vise. Apply a thin film of lubricant to the

5. Examine the strain relief boot and TIG adapter for
correct assembly. The boot should nest into the
Twist-Mate receptacle on the power source. The
boot face will be 1/8 inch away from the machine
front. All electrical surfaces should be completely
covered when in the Twist-Mate receptacle on the
power source. For more details see M19116PRINT
included with the machine.
STICK ELECTRODE CABLE CONNECTION
The Twist-Mate connection allows fast and reliable
stick electrode attachment to the electrode terminal of
the Square Wave TIG 275 welding power supply.
Assemble the stick electrode cable by attaching the
correct Twist-Mate adapter and electrode holder to an
adequately-sized welding cable. The Twist-Mate cable
plug is NOT provided with the machine for the stick
electrode connection. See Table A.1 and A.2 for rec-
ommended sizes and corresponding hardware.
Assemble the correct Twist-Mate adapter plug to the
stick electrode cable as detailed in "Work Cable
Connection".
WARNING
DO NOT CONNECT A TIG TORCH AND STICK
ELECTRODE CABLE AT THE SAME TIME. THEY
WILL BOTH BE ELECTRICALLY HOT WHENEVER
THE OUTPUT CONTACTOR IS ENERGIZED.
