WELDING SPARKS can cause fire or explosion. •Do not weld near flammable material . •Do not weld on containers that have held flammable material. MOVING PARTS can injure. •Keep away from moving parts •Do not operate with doors open or guards off. •Stop engine before servicing. ENGINE EXHAUST can kill. •Use in open, well ventilated areas or vent exhaust outside. ADDITIONAL SAFETY PRECAUTIONS Always operate the welder with the hinged doors closed as these provide maximum protection from moving parts and insure proper cooling air flow. Read carefully the Safety Precautions page in the Instruction Manual before operating this machine. Always follow these and any other safety procedures included in this manual and in the engine instruction manuals. GENERAL DESCRIPTION The SAE-400 is a diesel engine driven welding power source.The machine uses a DC generator 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 engine 1104C-44 is a 68.4 Hp @ 1725 RPM (51kw), 4-cylinder water cooled diesel made by Perkins. • Keep your head out of fumes. The engine 1104A-44 is a 64.4 Hp @ 1710 RPM • Use enough ventilation or exhaust at the arc, or (48kw), 4-cylinder water cooled diesel made by Perkins. SAE-400 B-2 OPERATION B-2 RECOMMENDED APPLICATIONS OTHER FEATURES 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 applications. •Continuous adjustment of both voltage and current for unsurpassed welds on demanding jobs. •Remote control capability standard. FOR AUXILIARYPOWER •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 (within the limits shown on the chart below). •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 standard. •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.

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” ( / ) idle position, the idler operates 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. ENGINE TEMPERATURE GAUGE Displays the coolant temperature in the engine block. ENGINE OIL PRESSURE GAUGE Displays the oil pressure to the engine. When the engine starts running, watch for the oil pressure to build up. If no pressure shows within 30 seconds, stop the engine and consult the engine instruction manual. BATTERY CHARGING AMMETER Displays the current going from the charging alternator into the batteries. It is normal for charging current to be high (above 15 amps) after starting or when the batteries are .low. on charge.
