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.

DESIGN FEATURES AND ADVANTAGES
FOR STICK WELDING
• Excellent DC constant current output for stick weld-
ing applications.
• Continuous adjustment of both voltage and current
for unsurpassed welds on demanding jobs.
• Remote control capability standard.
FOR AUXILIARY POWER
• 3,000 watts of 115/230 VAC, 60 Hz auxiliary power.
• One 20 amp 115 VAC duplex receptacle for up to 26
amps of 115 VAC power.
• One 15 amp, 230 VAC duplex receptacle for up to 13
amps of 230 VAC power.
• Weld and AC auxiliary power at the same time (with-
in the limits shown on the chart below).
OTHER FEATURES
• Perkins 4-cylinder, water cooled diesel engine.
Designed for long life, easy maintenance and excel-
lent fuel economy.
• Engine protection system shuts the engine down for
low engine oil pressure or high coolant temperature.
• Electronic Engine Idler. Engine automatically goes
to low idle in 10 to 14 seconds after welding or use
of auxiliary power stops. Includes high idle switch.
• Gauges for engine oil pressure, coolant temperature
and battery charging ammeter.
• Engine hour meter standard.
• Extended range 22.5 gallon (85.1 L) fuel tank.
FOR COMPRESSED AIR (SAE400 WELD ’ N AIR only)
• 35 CFM at 100 PSI for air arc gouging and air pow-
ered 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.
