“
Control”
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: 
Starting/Shutdown Instructions
Starting the Engine
WARNING
• Do not touch electrically live parts of electrode with skin or wet clothing.
•Keep flammable material away.
•Insulate yourself from work and
ground. Wear eye, ear, and body protection.
• Keep your head out of the fumes.
• Use ventilation or exhaust to remove fumes from breathing zone.
Be sure all
Remove all loads connected to the AC power recepta- cles. To start the engine, set the “Idler Control” switch in
the Automatic ( 
/
) position. Open the fuel valve on the supply cylinder. Always pull the choke control out when starting the engine; cold, warm or hot. Place the
“Engine” switch in the “ON” 
position. Push the “START” button and crank the engine until it starts. Release the button as soon as the engine starts. Do not push the “START” button while the engine is running because this will cause damage to the ring gear and/or starter motor. After the engine has started, slowly return the choke control to the full “in” position (Choke Open).
