The welding arc is “cold.” The engine runs normally (3700 RPM, no load). Auxiliary power is func- tioning normally.
POSSIBLE AREAS OF
MISADJUSTMENT(S)
WELDING PROBLEMS
1.Check for loose or faulty con- nections at the weld output terminals and welding cable con- nections.
2.The welding cable may be too long or coiled, causing an exces- sive voltage drop.
RECOMMENDED
COURSE OF ACTION
1.Check for the correct open cir- cuit voltage (OCV) at the welder output terminals – 66 VAC is normal.
If the correct voltage is present at the output terminals, check for loose connections on the heavy
2.If the OCV is low at the welder output terminals, perform
Engine Throttle Adjustment Test.
3.Check for shorted or grounded windings in the reactor (L1) and also in the main stator. See the Wiring Diagram.
