TWIST-MATE ADAPTER FOR LA-9 and LA-17 TIG TORCH

The Twist-Mate connection allows fast and reliable TIG torch connections to the electrode terminal of the Square Wave TIG 275. The Twist-Mate adapter, strain relief boot and retaining compound needed to connect an LA-9 or LA-17 torch (or any equivalent air-cooled TIG torch with a right-hand male 3/8-24 fitting) are included with the Square Wave TIG 275.

Assemble the the LA-9 or LA-17 TIG torch to the Twist- Mate adapter as follows:

1.Slide the strain relief boot over the TIG torch’s power cable with gas fitting.

2.Apply a small amount of retaining compound to the fitting threads as shown. Thread the fitting to the TIG adapter and tighten to ensure a sealed gas connection and a good electrical connection. (35-45 in-lbs)

3.Hold the TIG adapter, with cable installed, firmly in place by securing it into the Twist-Mate receptacle on the power source or into a padded vise. Align the hex in the boot with the hex on the adapter. Firmly push the boot onto the adapter, rocking the boot to assist installation. Use soap for lubricant if required.

COMPLETED ASSEMBLY

4.Examine the strain relief boot and TIG adapter for correct assembly. The boot should nest into the Twist-Mate receptacle on the power source. All electrical surfaces should be completely covered when in the Twist-Mate receptacle on the power source. For more details see M19115PRINT includ- ed with the machine.

TWIST-MATE ADAPTER FOR LW-18 and LW-20 TIG TORCH

The Twist-Mate connection allows fast and reliable TIG torch connections to the electrode terminal of the Square Wave TIG 275. The Twist-Mate adapter and strain relief boot needed to connect an LW-18 or LW-20 torch (or any equivalent water-cooled TIG torch with the fittings shown in the diagrams under step 2 and 3) are included with the Square Wave TIG 275.

Assemble the the LW-18 or LW-20 TIG torch to the Twist-Mate adapter as follows:

1.Slide the strain relief boot over the TIG torch’s power/water cable (large fitting) and gas hose (small fitting without notches on hex). Also slide a water hose into the strain relief boot as shown.

2.Thread the power/water cable (large fitting) from the torch to the large port on the TIG adapter and tight- en to ensure a water tight connection. Next, thread the gas hose (small fitting without notches on hex) to the port marked “G” on the TIG adapter and tight- en to ensure a sealed gas connection. Next, thread the water hose to cooler (or to water drain) to the port marked “W” on the TIG adapter.
