SECTION 6 OPERATING THE WELDING GENERATOR
If the unit is extremely overloaded, weld and generator power will stop. Turn unit off and
restart to reset the generator protection circuit and restore weld generator power output.
If the rated output of the unit is exceeded, engine speed may vary rapidly until the weld or
generator load is reduced.
