ing auxiliary equipment. If unit does
not have GFCI receptacles, use
GFCI-protected extension cord.
!
Unplug power cord before attempt-
ing to service accessories or tools.
.
Generator power decreases as weld
current or air compressor output in-
creases.
1 120/240 V 50 A AC Receptacle RC1
2 120 V 20 A AC Receptacles RC2
and RC3 (GFCI Receptacles Shown)
RC1 supplies 60 Hz single-phase power at
weld/power speed. Maximum output is
11.0 kVA/kW.
RC2 and RC3 supply 60 Hz single-phase
power at weld/power speed. Maximum out-

set button pops out, red light turns on, and
the circuit opens to disconnect the faulty
equipment. Check for damaged tools,
cords, plugs, etc. connected to the recep-
tacle. Press button to reset receptacle and
resume operation.

from overload. If a supplementary protector
opens, the receptacle does not work.
.
Press button to reset supplementary
protector. If supplementary protector
continues to open, contact Factory
Authorized Service Agent.
Combined output of all receptacles limited
to 10 kVA/kW rating of the generator.
EXAMPLE: If 20 A is drawn from each 120
V duplex receptacle, only 20 A is available
at the 240 V receptacle:
