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 100 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. Check the resistance of
the toroidal current transformer.
The resistance should measure
10 to 14 Ohms.
The Idler/Engine Protection PC
board may be faulty.
