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 Supplementary Protector 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.
6 Supplementary Protectors 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.
7 Supplementary Protector CB4
CB4 protects RC4 from overload. If CB4
opens, the receptacle does not work. Place
switch in On position to reset.
. If a supplementary protector 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
