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

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.
DUTY CYCLE
Duty cycle is based on a ten minute period and opera-
tion in an ambient temperature of 104°F(40°C).
The SAE-400 SEVERE DUTY 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.
