Welder Controls - Function and Operation
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 de-energized
to shut down the engine.
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).
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.
