GENERAL DESCRIPTION

The SAE-400 SEVERE DUTY is a diesel engine driven welding power source. The machine uses a DC gener- ator 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 engine is a 71 Hp (54kw), 4-cylinder water cooled diesel made by Perkins.

RECOMMENDED APPLICATIONS

WELDER

The SAE-400 SEVERE DUTY provides excellent con- stant current DC welding output for stick (SMAW) weld- ing.

AUXILIARY POWER

The SAE-400 SEVERE DUTY provides 3 KW of 115/230 VAC output for auxiliary power and emer- gency standby power.
