COURSE OF ACTION

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely,

contact the Lincoln Electric Service Department for technical troubleshooting assistance before you proceed.

Call 1-888-935-3877.

CAUTION

The engine will not go to high

idle when using auxiliary power.

The automatic idle system

functions normally when welding.

Weld and auxiliary power is

normal when the idle switch is in

the “High Idle” position. The

engine starts, runs, and shuts

down normally.

The load applied to the

auxiliary receptacles may be

too low. A load of 150 Watts

minimum is required for the

idle system to operate reliably.
Check that any power cords

are in good condition and

properly connected.
Verify that any devices

operating from the auxiliary AC

power are operating correctly

and are in good condition. Try

plugging the device into

another source of AC power to

be sure it is functioning

properly.
Some devices may test the

input power for correct voltage

and frequency before they will

operate. If such a device is

being used, the idle switch will

need to be placed in the “High”

position. The current drawn by

many of these devices, when

testing the power, is too low to

reliably activate the automatic

idle system.

The Toroidal Current

Transformer or the wiring

connecting it to the

idler/engine protection PC

board may be faulty.
The idler/engine protection

PC board may be faulty.
