.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.

2120 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
