A-3 A-3 INST ALLA TION SELECT SUIT ABLE LOCA TION Locate the welder in a dry location where there is free circulation of clean air into the louvers in the back and out the front of the unit. A location that minimizes the amount of smoke and dirt drawn into the rear louvers reduces the chance of dirt accumulation that can block air passages and caus[...]

A-4 A-4 INST ALLA TION 3. Route the cable under and around the back of the Wire Feed Gearbox (6). 4. For GMAW Only: Refer to Figure A.2. As deliv- ered, the welder is wired for positive polarity. This is the appropriate configuration for the Gas Metal Arc Welding (GMAW) process. To complete instal- lation, use the provided wing nut to connect the w[...]

A-5 A-5 INST ALLA TION 3. Attach the flow regulator to the cylinder valve and tighten the union nut securely with a wrench. The flow regulator for carbon dioxide must have a plas- tic washer seated in the fitting that attaches to the cylinder to prevent leakage. 4. Refer to Figure A.6. Attach one end of inlet gas hose to the outlet fitting of the f[...]

A-6 A-6 INST ALLA TION CODE REQUIREMENTS FOR INPUT CONNECTIONS This welding machine must be connected to power source in accordance with applicable elec- trical codes.
