Y If unit does not have GFCI re-
ceptacles, use GFCI-
protected extension cord.
. Auxiliary 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. Maxi-
mum output is 8 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 output from RC2 or RC3 is
2.4 kVA/kW.
4 Circuit Breakers CB1 and CB2
CB1 and CB2 protect RC1 from over-
load. If CB1 or CB2 opens, RC1 and
one of the 120 volt receptacles does
not work. 120 volts may still be pres-
ent at RC1.
5 Circuit Breaker CB3
6 Circuit Breaker CB4
CB3 protects RC2 and CB4 protects
RC3 from overload. If a circuit break-
er opens, the receptacle does not
work.
. Press button to reset circuit
breaker. If breaker continues to
open, contact Factory
Authorized Service Agent.
Combined output of all receptacles
limited to 8 kVA/kW rating of the gen-
erator.
EXAMPLE: If 20 A is drawn from
each 120 V duplex receptacle, only
13 A is available at the 240 V
receptacle:
2 x (120 V x 20 A) + (240 V x 13 A) =
8 kVA/kW
