6-2. 240 Volt Duplex Receptacle (Optional)

Y If unit does not have GFCI re- ceptacles, use GFCI-pro- tected extension cord.

1 240 V 15 A AC Receptacle RC1

Receptacle supplies 60 Hz single-

1phase power at weld/power speed. Maximum output is 3 kVA/kW.

2 Circuit Breaker CB1

3 Circuit Breaker CB2

CB1 and CB2 protect the recep- tacles from overload. If CB1 or CB2 opens, the 240 V receptacle and half of the 120 V receptacle does not work. 120 volts may still be

23present at the 240 V receptacle. Press button to reset circuit breaker.

. If a circuit breaker continues to

open, contact a Factory Authorized Service Agent.

Combined output of all receptacles is 3 kVA/kW. Auxiliary power is not affected by weld output.

EXAMPLE: If 10 A is drawn from the 240 V receptacle, only 5 A is avail- able at the 120 V receptacle:

(240 V x 10 A) + (120 V x 5 A) = 3.0 kVA/kW
