SECTION 6 – OPERATING AUXILIARY EQUIPMENT
6-1. Auxiliary Power Receptacles And Circuit Breakers
Y If unit does not have GFCI recep-
tacles, use GFCI-protected exten-
sion cord.
.
Auxiliary power decreases as weld
current increases.
1 240 V 50 A AC Receptacle RC3
RC3 supplies 60 Hz single-phase power at
weld/power speed. Maximum output is 12
kVA/kW.
2 120 V 15 A AC Duplex Receptacle
RC2
3 120 V 15 A AC Duplex Receptacle
RC1
RC2 and RC1 supply 60 Hz single-phase
power at weld/power speed. Maximum out-
put from RC2 or RC3 is 1.8 kVA/kW.
4 240 V 30 A, AC Twistlock Receptacle
RC6
RC6 supplies 60 Hz three-phase power at
weld/power speed. Maximum output is 12
kVA/kW.
5 Circuit Breaker CB3
CB3 protects RC1, RC2, and RC3 from
overload. If CB3 opens, RC1, RC2, and
RC3 do not work. Place switch in On posi-
tion to reset breaker.
6 Circuit Breakers CB1 And CB2
CB1 protects RC1 and CB2 protects RC2
from from overload. If CB1 or CB2 opens,
the receptacle does not work. Press button
to reset breaker.
7 Circuit Breaker CB13
CB13 protects RC6 from overload. If CB13
opens, the receptacle does not work. Push
breaker bar up to reset.
.
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 RC1 and
RC2, only 37 A is available at RC3:
2 x (120 V x 13 A) + (240 V x 28 A) = 12
kVA/kW
