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

CAUTION

Never change the “Polarity” switch setting while welding. This will damage the switch.

CAUTION

CONTROL” SWITCH

Provides a fine welding current adjustment within the Range Switch settings in the STICK/TIG mode and welding voltage control with the Range switch set in the wire feed mode.

“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:

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.

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.

If a GFCI receptacle is tripped, See the MAINTE- NANCE section for detailed information on testing and resetting the GFCI receptacle.

Never change the “RANGE” Switch setting while welding. This will damage the switch.
