Receptacles supply 60 Hz single- phase power at weld/power speed.

 

 

 

If a ground fault is detected, GFCI

Circuit Breaker CB2

 

 

 

 

CB1 protects RC1 and the genera-

 

 

 

tor winding from overload. If CB1

 

 

 

opens, RC1 and GFCI1 do not

 

 

 

work. Place switch in On position to

 

 

 

reset breaker.

 

 

 

 

 

 

CB2 protects GFCI1 from overload.

 

 

 

 

 

 

If CB2 opens, GFCI1 does not

 

 

 

work. Press button to reset breaker.

 

 

 

. If a circuit breaker continues to

 

 

 

 

open, contact Factory Autho-

 

 

 

 

rized Service Agent.

 

 

 

 

. Generator

power

is not

af-

 

 

 

 

fected by weld output.

 

Maximum output is 2.4 kVA/kW from GFCI1 and 4 kVA/kW from RC1. Maximum output from all re- ceptacles is 4 kVA/kW.

EXAMPLE: If 13 A is drawn from RC1, only 7 A is available at GFCI1:

(240 V x 13 A) + (120 V x 7 A) = 4.0 kVA/kW
