“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
