Set Fine Adjust control R1 at 10
for full auxiliary power.
1 240 V 30 A AC Receptacle
RC1
RC1 supplies 60 Hz single-phase
power at weld/power speed. Maxi-
mum output is 7.2 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
overload. If CB1 or CB2 opens,
RC1 does not work. 120 volts may
still be present at RC1.
5 Circuit Breaker CB3

13 A is available at the 240V
receptacle:
2 x (120 V x 20 A) + (240 V x 15 A)
= 8.4 kVA/kW
