SECTION 7 − OPERATING AUXILIARY EQUIPMENT
7-1. Generator Power Receptacles And Circuit Breakers
 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 12
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.
4 240 V 30 A, AC Twistlock Receptacle
RC4
RC4 supplies 60 Hz three-phase power at
weld/power speed. Maximum output is 12
kVA/kW.
5 Circuit Breaker CB1
CB1 protects RC1, RC2, and RC3 from
overload. If CB1 opens, RC1, RC2, and
RC3 do not work. Place switch in On posi-
tion to reset breaker.
6 Circuit Breakers CB2 And CB3
CB2 protects RC2 and CB3 protects RC3
from from overload. If CB2 or CB3 opens,
the receptacle does not work. Press button
to reset breaker. Place switch in On posi-
tion to reset breaker.
7 Circuit Breaker CB4
CB4 protects RC4 from overload. If CB4
opens, the receptacle does not work. Place
switch in On position to reset breaker.
 If a breaker continues to open, contact
Factory Authorized Service Agent.
Combined output of all receptacles limited
to 12 kVA/kW rating of the generator.
EXAMPLE: If 13 A is drawn from RC2 and
RC3, only 37 A is available at RC1:
2 x (120 V x 13 A) + (240 V x 28 A) = 12
kVA/kW
