GENERAL DESCRIPTION

The SAE400 or SAE400 WELD’N AIR is a diesel engine driven welding power source. The machine uses a DC generator for DC stick electrode welding and an AC exciter for 115/230 VAC auxiliary power. As a generator it can supply up to 3,000 watts of 115/230 volt AC power. As a welder it provides up to 575 amps of DC constant current output. The belt driven air com- pressor of the SAE400 WELD’N AIR provides 35 CFM at 100 PSI compressed air.

The engine is a 71 Hp (54kw), 4-cylinder water cooled diesel made by Perkins.
