GENERAL DESCRIPTION
The SAE400 WELD’N AIR is a diesel engine driven
welding power source. The machine uses a DC gen-
erator 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 compressor provides
35 CFM at 100 PSI compressed air.
The engine is a 63 Hp (47kw), 4-cylinder water cooled
diesel made by Perkins.
RECOMMENDED APPLICATIONS
WELDER
The SAE400 WELD’N AIR provides excellent constant
current DC welding output for stick (SMAW) welding.
The field installed optional CV Adapter (K385-1) pro-
vides up to 500 amps at 35 volts of constant voltage
output for semiautomatic welding.
AUXILIARY POWER
The SAE400 WELD’N AIR provides 3 KW of 115/230
VAC output for auxiliary power and emergency stand-
by power.
COMPRESSED AIR
The SAE400 WELD’N AIR provides 35 CFM at 100
PSI compressed air for air arc gouging and air powered
tools.
