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 15 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).
FOR COMPRESSED AIR
• 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.
• No welding output derating required at maximum
compressor load.
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 oil pressure or high coolant temperature.
• Gauges for engine oil pressure, coolant temperature,
battery charging ammeter, compressor air pressure
and compressor oil pressure.
• Indicator light for compressor operation.
• Engine hour meter standard.
• Extended range 22.5 gallon (85.1 L) fuel tank.
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 WELD’N AIR is 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 is rated at a 60% duty cycle based
on a ten minute period as described above.
