.
Weld output and 60 Hz generator
power output at receptacles RC1
and RC2 are not available at the
same time. When welding, gen-
erator power is available from AC
receptacle RC3 only (see Sec-
tion 7-2).
.
Generator power is available at
receptacles RC1 and RC2 only at
1800 rpm. If generator is not
locked at 1800 rpm, engine
speed increases in response to
weld load and generator power
output stops at receptacles RC1
and RC2. Generator power load
does not affect engine speed.
1 240 V 50 A AC Receptacle RC1
RC1 supplies 60 Hz single-phase
power at 1800 rpm. Maximum output
is 5 kVA/kW(20 A at 240 volts ac). For
60 Hz generator power at RC1, set
controls as shown in table.
2 120 V 20 A AC Duplex
Receptacle RC2
RC2 supplies 60 Hz single-phase
power at 1800 rpm. Maximum output
from RC2 is 2.4 kVA/kW (20 A at 120
volts ac).
3 Circuit Breaker CB1
CB1 protects receptacles RC1 and
RC2 from overload. If CB1 opens, the
receptacles do not work. Place switch
in On position to reset breaker.
4 Circuit Breaker CB3
CB3 protects RC2 from overload. If
CB3 opens, the receptacle does not
work. Press button to reset breaker.
.
If circuit breaker continues to
open, contact Factory
Authorized Service Agent.
Combined output of all receptacles
limited to 5 kVA/kW continuous rating
of the generator.
EXAMPLE: If 10 A is drawn from 120
V duplex receptacle RC2, only 16 A is
available at 240 V receptacle RC1.
(120 V x 10 A) + (240 V x 16 A) = 5
kVA/kW
