SECTION 7 − OPERATING AUXILIARY EQUIPMENT

.

.

.

If the unit is extremely overloaded, weld and generator power will stop. Turn unit off and restart to reset the generator protection circuit and restore weld generator power output.

If the rated output of the unit is exceeded, engine speed may vary rapidly until the weld or generator load is reduced.

The welding generator provides power while welding and with the Amperage control in any position. However, under these conditions equipment

connected to the welding generator may be subject to larger than normal voltage fluctuations. It is recommended that only lamps be powered under these conditions.

7-1. Standard Receptacles

!

If unit does not have GFCI re-

ceptacles, use GFCI- protected extension cord.

tacle 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 Supplementary Protector CB1

CB1 protects the ac receptacles from overload. If CB1 opens, the ac receptacles do not work.

.Move CB1 toggle switch to On

position to reset. If supplemen- tary protector continues to

open, contact Factory Authorized Service Agent.

6Supplementary Protector CB3

CB2 protects RC2 and CB3 pro- tects RC3 from overload. If a sup- plementary protector opens, the re- ceptacle does not work.

.Press button to reset. If supple-

mentary protector continues to

open, contact Factory Authorized Service Agent.

Combined output of all receptacles limited to 10 kVA/kW rating of the generator.

EXAMPLE: If 20 A is drawn from each 120 V duplex receptacle, only 21 A is available at the 240V receptacle:

2 x (120 V x 20 A) + (240 V x 21 A) = 10 kVA/kW (approx.).
