SECTION 6 – OPERATING AUXILIARY EQUIPMENT
6-1. 120 Volt And 240 Volt Duplex Receptacles

Y If unit does not have GFCI recep-
tacles, use GFCI-protected exten-
sion cord.

contact Factory Authorized Service
Agent.
.

output.
1 240 V 15 A AC Receptacle RC1
2 120 V 15 A AC Receptacle RC2
Receptacles supply 60 Hz single-phase
power at weld/power speed.
3 Circuit Breakers CB1 And CB2
CB1 protects RC1 and CB2 protects RC2
from overload. If CB1 or CB2 opens, the re-
ceptacle does not work. 120 volts may still
be present at RC2.
Maximum output from each duplex recep-
tacle is 1.8 kVA/kW, and 3 kVA/kW from all
receptacles.
EXAMPLE: If 10 A is drawn from RC1, only
5 A is available at RC2:
(240 V x 10 A) + (120 V x 5 A) = 3.0 kVA/kW
