TESTING THE GFCI SENSING MODULE
If tripping of the
main
circuit breaker persists after a load is
replaced with a known good one (no short circuit), perform
this test with no load.
1. Start the welder-generator as outlined in the start up
procedure in this manual.
2. Place the main circuit breaker, CB1 (Figure 49) in the
ON
position.

and the
red
FAULT LED turns
