RECOMMENDED APPLICATIONS

WELDER

The SAE400 or SAE400 WELD’N AIR provides excel- lent constant current DC welding output for stick (SMAW) welding. The field installed optional CV Adapter (K385-1) provides up to 500 amps at 35 volts of constant voltage output for semiautomatic welding.

AUXILIARY POWER

The SAE400 or SAE400 WELD’N AIR provides 3 KW of 115/230 VAC output for auxiliary power and emer- gency standby power.

COMPRESSED AIR

The SAE400 WELD’N AIR only, provides 35 CFM at 100 PSI compressed air for air arc gouging and air powered tools.

•11 Gallon air receiver tank system with integral over- pressure relief valve for smooth air delivery.

•Indicator light for compressor operation.

•Gauges for compressor air pressure and compres- sor oil pressure.

•No welding output derating required at maximum compressor load.

DUTY CYCLE

Duty cycle is based on a ten minute period and opera- tion in an ambient temperature of 104°F(40°C).

The SAE400 & SAE400 WELD’N AIR are NEMA rated at 60% duty cycle. Duty cycle is based on a ten minute period. Therefore, a 60% duty cycle welder can be operated at nameplate rated output for 6 minutes out of every 10 minute period without overheating.

The auxiliary power can be used continuously (100% duty cycle) within its rated current capacities.

The air compressor on the SAE400 WELD’N AIR is rated at a 60% duty cycle based on a ten minute peri- od as described above.
