SAE-400
®

RECOMMENDED APPLICATIONS

WELDER
The SAE-400® provides excellent constant current DC welding
output for stick (SMAW) welding. The field installed optional CV
Adapter (K385-[ ]) provides up to 500 amps at 35 volts of constant
voltage output for semiautomatic welding.
AUXILIARY POWER
The SAE-400® provides 3 KW of 115/230 VAC output for
auxiliary power and emergency standby power.

DESIGN FEATURES AND ADVANTAGES

FOR STICK WELDING
• Excellent DC constant current output for stick welding appli-
cations.
• Continuous adjustment of both voltage and current for
unsurpassed welds on demanding jobs.
• Remote control capability standard.
FOR AUXILIARY POWER
• 3,000 watts of 115/230VAC, 60 Hz auxiliary power.
• One 20 amp 115VAC duplex receptacle.
• One 15 amp, 230VAC duplex receptacle for up to 13 amps of
230VAC power.
• One 115VAC (European IEC-309) 16 amp receptacle.
• One 230VAC (European IEC-309) 15 amp receptacle.

OTHER FEATURES
• Perkins 4-cylinder, water cooled diesel engine. Designed for
long life, easy maintenance and excellent 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 / fuel gauge standard (code 12311).
• Engine hour meter standard (Code 11605, 11807, 11966)
• Extended range 22.5 gallon (85.1 L) fuel tank.

DUTY CYCLE

Duty cycle is the percentage of time the load is being applied in a
10 minute period. For example a 60% duty cycle, represents 6
minutes of load and 4 minutes of no load in a 10 minute period.

ENGINE CONTROLS

IGNITION SWITCH
When placed in the "ON" position, this switch energizes the fuel
solenoid. When placed in the "OFF" position, the flow of fuel to the
injection pump is stopped to shut down the engine.
"IDLER" switch
The idler switch has two positions, "HIGH" and "AUTO".
When in "HIGH" ( ) position, the engine will run continuously
at high idle.
When in "AUTO" ( /
as follows:
a. Welding
When the electrode touches the work, the welding arc is
initiated and the engine accelerates to full speed.
After welding ceases (and no auxiliary power is being drawn),
the engine will return to low idle after approximately 10 to 14
seconds.
b. Auxiliary Power
With the engine running at low idle and auxiliary power for
lights or tools is drawn (approximately 100-150 watts or
greater) from the receptacles, the engine will accelerate to
high speed. If no power is being drawn from the receptacles (
and not welding) for 10-14 seconds, the idler reduces the
engine speed to low idle.
