“CONTROL AT WELDER /

REMOTE CONTROL” Switch

The toggle switch on the control panel labeled “CONTROL AT WELDER” and “REMOTE CONTROL” gives the operator the option of controlling the output at the welder control panel or at a remote station. Remote connections are made at the 6-pin or 14-pin amphenol connector.

For remote control, the toggle switch is set in the “REMOTE CONTROL” position.

For control at the welder control panel, the toggle switch is set in the “CONTROL AT WELDER” position.

“WELDING TERMINALS” Switch

The toggle switch labeled “WELDING TERMINALS ALWAYS ON” and “WELDING TERMINALS REMOTELY CONTROLLED” is used to control the operation of the welder output contactor.

With the switch in the “ALWAYS ON” position, the output contactor is closed at LOW and HIGH idle.

With the switch in the “REMOTELY CONTROLLED” position, the contactor is open at LOW idle and HIGH idle until a control cable is attached to the welder amphenol connector from a wire feeder. Under this condition, contactor closes when the wire feeder trigger is depressed and opens when the trigger is released.

“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:

a. Welding

Low idle and in the “WELDING TERMINALS ALWAYS ON” mode - Stick Welding only. When the electrode touches work, the welding arc is initiated and the engine accelerates to full speed.

Low idle and in the “WELDING TERMINALS REMOTELY CONTROLLED” mode -Wire Welding Only Pressing the gun trigger closes the Ranger 9 output contactor and causes the engine to accelerate to full speed.

After the gun trigger is released and/or welding ceases (and no auxiliary power is being drawn), the engine will return to low idle after approximately 10 to 14 seconds.

b.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.

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 Pre-Operation Maintenance has been per- formed. Also, read the Engine Owner’s Manual.

Remove all loads connected to the AC power recepta- cles. To start the engine, set the “Idler Control” switch

in the Automatic ( /) position.

Use the choke control as follows:

Onan Engine - If the engine is cold, pull the choke control out. Do not use the choke if the engine is warm or hot.

Kohler Engine - 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).

After running at high engine speed for 10-14 seconds, the engine will go to low idle.

Allow the engine to warm up by letting it run at low idle for a few minutes.
