OPERATING INSTRUCTIONS
Additional Safety Precautions
Always operate the welder with the roof and case sides in place as this provides maximum protection from moving parts and assures 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 Manual.

Welder Controls - Function and Operation
Explanation of Symbols that Appear on this Equipment
ON | OFF | Low Idle | High Idle |
ENGINE “ON-OFF” Switch
When placed in the “ON” position, this switch energizes the engine ignition circuit. When placed in the “OFF” position, the ignition circuit is
ENGINE “START” Push-Button Switch
Energizes engine starter motor.
“POLARITY” Switch
Three STICK/TIG (constant current) polarity settings:
DC+, DC- and AC
Two wire feed (constant voltage) settings:
DC+ and DC-
NOTE: The setting of this switch must match the color band setting of the Range Switch (both switches must be set for the same welding process).
CAUTION
Never change the “POLARITY” switch setting
while welding. This will damage the switch.
