!
If unit does not have GFCI recep-
tacles, use GFCI-protected exten-
sion cord.
Generator power decreases as weld
current increases.
1
240 V 50 A AC Receptacle RC1
RC1 supplies 60 Hz single-phase power at
weld/power speed. Maximum output is 11
kVA/kW.
2
120 V 20 A AC Duplex Receptacle
RC2
3
120 V 20 A AC Duplex Receptacle
RC3
RC2 and RC3 supply 60 Hz single-phase
power at weld/power speed. Maximum out-
put from RC2 or RC3 is 2.4 kVA/kW (20 A
x 120 V).
4
Supplementary Protector CB1
CB1 protects receptacles RC1, RC2, RC3,
and 115 volt AC output to Remote Recep-
tacle RC4 from overload. If CB1 opens, the
receptacles do not work and 115 volt AC
output to Remote Receptacle RC4 stops.
Place switch in On position to reset.

Supplementary Protector CB2
6
Supplementary Protector CB3
CB2 protects RC2 from overload. CB3 pro-
tects RC3 and the 115 volt AC output to Re-
mote Receptacle RC4 from overload. If
CB2 opens, RC2 does not work. If CB3
opens, RC3 does not work and the 115 volt
AC output to RC4 stops. Press button to re-
set.
If supplementary protector continues to
open, contact Factory Authorized Ser-
vice Agent.
Combined output of all receptacles limited
to peak rating of the generator.
Example: If 20 A is drawn from each 120 V
duplex receptacle, only 25 A is available at
the 240 V receptacle:
2 x (120 V x 20 A) + (240 V x 25 A) = 11 kVA/
kW

7-2. Optional GFCI Receptacles
!
Use GFCI protection when operating auxiliary
equipment. If unit does not have GFCI recep-
tacles, use GFCI-protected extension cord.
Generator power decreases as weld current in-
creases.
Combined output of all receptacles limited to 11 kVA/
kW peak rating of the generator.
GFCI Receptacle Option
1
120 V 20 A AC GFCI Receptacles GFCI-2 and
GFCI-3
GFCI2 and GFCI3 supply 60 Hz single-phase power
at weld/power speed. Maximum output from GFCI-2 or
GFCI-3 is 2.4 kVA/kW. Circuit protection is the same
as standard receptacles.
If a ground fault is detected, the GFCI Reset button
pops out, red light turns on, and the circuit opens to dis-
connect the faulty equipment. Check for damaged
tools, cords, plugs, etc. connected to the receptacle.
Press button to reset receptacle and resume opera-
tion.
At least once a month, run engine at weld/power
speed and press Test button to verify GFCI is
working properly.
!
If GFCI red light blinks continuously, replace
receptacle.
