SELECT SUITABLE LOCATION

Place the machine on a secure, level surface or rec- ommended undercarriage. The machine may topple over if this procedure is not followed. To minimize over heating, locate the welder in a dry location where there is free circulation of clean air. Do not place on com- bustible surfaces.

STACKING

Machines cannot be stacked.

CHANGING POLARITY

1.For Negative Polarity Welding (DC-): Refer to Figure A.2. As delivered, the machine is wired for Negative polarity with the gun cable connected to the Negative (-) output terminal and the work cable to the Positive (+) output terminal. Make sure that both thumbscrews are tight. This is the typical con- figuration for Flux Cored Welding (FCAW).

2.For Positive Polarity Welding (DC+): Refer to Figure A.3. To wire for Positive polarity, connect the gun cable to the Positive (+) output terminal and the work cable to the Negative (-) terminal. This is the typical configuration for the Metal Inert Gas (MIG) process. Make sure that both thumbscrews are tight.

GAS INLET FITTING

POWER INPUT CABLE

Refer to Figure A.4.

The machine has two input connections, the power input cable and the gas inlet fitting. The power input cable and gas inlet fitting are located on the rear.

GAS CONNECTION

When using the MIG process, a cylinder of shielding gas (appropriate for the metal being welded) must be obtained.

WARNING

CYLINDER may explode if damaged. Keep cylinder upright and chained to support.

• Keep cylinder away from areas where it may be damaged.

•Never lift welder with cylinder attached.

•Never allow welding electrode to touch cylinder.

•Keep cylinder away from welding or other live electrical circuits.

BUILDUP OF SHIELDING GAS may harm health or kill.

• Shut off shielding gas supply when not in use.

•SEE AMERICAN NATIONAL STANDARD Z-49.1, “SAFETY IN WELDING AND CUTTING” PUB- LISHED BY THE AMERICAN WELDING SOCIETY.
