TIG TORCH CONNECTION

The Precision TIG torch connection box, located on the right side of the machine, provides all the input and output connections for the installation of both air- cooled and water-cooled TIG torches with fittings con- forming to Compressed Gas Association (CGA) stan- dards:

Note: The Precision TIG provides an insulated Torch Reel and Holster for handy and safe storage of con- nected torch when not welding, and excess torch cable length while welding.

WARNING

Combination connectors (Power/Water and Power/Gas) are electrically "hot" while welding in STICK or TIG modes.

If using an Air-Cooled Torch be sure coolant is shut off and/or Cooler is unplugged from the Precision TIG Water Cooler Receptacle on the torch side of the upper case back.

Observe the safety precautions necessary for han- dling and using compressed gas containers. Contact your supplier for specifics.

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 cir- cuits.

•Maximum inlet pressure 150 psi.

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

The Precision TIG machines do not have Hi-Freq. available at the Stick electrode stud, therefore stud connection adapters (such as LECO. S19257-series) cannot be used for torch connection.

Single-piece cable air-cooled torches with a 3/8-24 RH connector fitting (such as the Magnum PTA-9/-17, or LA- 9/-17) require the provided S20403-4 Torch Connector, while those with a 7/8-14 RH connector fitting (such as the Magnum PTA-26, or LA-26) require the available K2166-1 Torch Connector. (See Figure A.3)

Two-piece cable air-cooled torches (such as PTA-, or LA- torches) can be used with the available K2166-2 1/2” Stud Connector with with a 7/8-14 LH male fitting.

Magnum PTW-18/-20 (or LW-) water-cooled Torches require no adapter for Precision TIG connection.
