Lincoln Electric IM703-A manual TIG Torch Connection, Figure A.2

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.
