B-2 OPERA TION B-2 RECOMMENDED APPLICA TIONS WELDER The SAE400 or SAE400 WELD’N AIR provides excel- lent constant current DC welding output for stick (SMA W) welding. The field installed optional CV Adapter (K385-1) provides up to 500 amps at 35 volts of constant voltage output for semiautomatic welding.
B-3 OPERA TION B-3 ENGINE CONTROLS IGNITION SWITCH When placed in the “ON” position, this switch ener- gizes the fuel solenoid. When placed in the “OFF” posi- tion, 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”.
B-4 OPERA TION B-4 How to Set the Controls Assume you want a normal soft arc and about 135 amps, using a 5/32” (4.0 mm) electrode: 1. Set the “Job Selector” at the center of the black range. 2. Set the “Current Control” to read 135 amps on the black dial.
B-5 OPERA TION B-5 ENGINE OPERA TION Do not adjust the high idle engine speed (rpm) above the factory setting specification as this will overspeed the air compressor and void it’s warranty . ------------------------------------------------------------------------ ST ARTING INSTRUCTIONS Be sure all Pre-Operation Maintenance has been per- formed.
C-1 ACCESSORIES C-1 K930-2 Hi-Freq ™ - Provides high frequency plus a gas valve for TIG welding. A water valve is available as an option. Requires 1 15 volt AC input. (Limited to 250A - 60% Duty Cycle). K802-D Power Plug Kit - Kit includes male plugs for each auxiliary receptacle.
D-1 MAINTENANCE D-1 ELECTRIC SHOCK can kill. ● Do not touch electrically live parts such as output terminals or inter- nal wiring ENGINE EXHAUST can kill.
D-2 MAINTENANCE D-2 COMMUT A TOR AND BRUSH MAINTENANCE Uncovered rotating equipment can be dangerous. Use care so your hands, hair , clothing or tools do not catch in the rotating parts. Protect yourself from particles that may be thrown out by the rotat- ing armature when stoning the commutator .

Brush of f any debris and rinse in diesel fuel. 6. Re-install the pre-filter screen into the upper cavity of the filter header making sure the four pull tabs are pointing up.
D-4 MAINTENANCE D-4 SP ARK ARRESTOR • Spark Arrester and Muffler may be hot! • Allow engine to cool before servicing spark arrester! • Do not operate engine while servicing spark arrester! For machines with separate spark arresting units: Service the spark arrestor every 100 hours of opera- tion or twice a year , which ever occurs first.
