.Auxiliary power decreases as weld current increases.

Combined output of all receptacles

1limited to 8 kVA/kW rating of the generator.

GFCI Receptacle Option

1120 V 15 A AC GFCI Recep- tacles GFCI2 and GFCI3

GFCI2 and GFCI3 supply 60 Hz single-phase power at weld/power speed. Maximum output from GFCI2 or GFCI3 is 2.4 kVA/kW. Cir- cuit breaker protection is the same as standard receptacles.

If a ground fault is detected, the GFCI Reset button pops out and the circuit opens to disconnect the faulty equipment. Check for damaged tools, cords, plugs, etc. connected to the receptacle. Press button to reset receptacle and resume operation.

.At least once a month, run engine at weld/power speed and press Test button to verify GFCI is working properly.
