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

Call 1-888-935-3877.

CAUTION

The welding arc is “cold.”

Engine

runs normally (3700 RPM no load).

Auxiliary power is functioning nor-

mally.

1. Check for loose or faulty connec-

tions at the weld output terminals

and welding cable connections.

2. The welding cable may be too

long or coiled, causing an exces-

sive voltage drop.

1. Check for the correct open cir-

cuit voltage (OCV) at the welder

output terminals (80VAC Max.

72VDC Max.).

If the correct

voltage is present at the output

terminals, then check for loose

connections on the heavy cur-

rent carrying leads inside the

EAGLE 8.

See

Wiring

Diagram.

2. If the OCV is low at the welder

output terminals, then Perform
The Engine Throttle Adjustment

Test.

3. Perform the

Output Rectifier

Bridge Test.

4. Check for shorted or grounded

windings in the reactor and also

in the main stator. See
