SECTION 7 − OPERATING AUXILIARY EQUIPMENT

7-1. Generator Power Receptacles

! If unit does not have GFCI recep- tacles, use GFCI-protected extension cord.

NOTICE − Disconnect equipment from auxil- iary power receptacles during start−up and shutdown. Some equipment can be dam- aged by changes in frequency as engine rpms change during start-up and shutdown.

. Generator power decreases as weld current increases.

Set Fine Control R1 at 10 for full genera- tor power.

1 240 V 50 A AC Receptacle RC1

RC1 supplies 60 Hz single-phase power at weld/power speed. Maximum output is 10 kVA/kW. See section 7-3for information on wiring optional 240 V single-phase plug.

2 120 V 20 A Duplex Receptacle RC2

3 120 V 20 A Duplex Receptacle RC3

RC2 and RC3 supply 60 Hz single-phase power at weld/power speed. Maximum out- put from RC2 or RC3 is 2.4 kVA/kW.

4 Supplementary Protector CB1

CB1 protects receptacles RC1, RC2, and RC3 from overload. If CB1 opens, the recep- tacles do not work. Place switch in On posi- tion to reset.

5Supplementary Protector CB2

6Supplementary Protector CB3

CB2 protects RC2 and CB3 protects RC3 from overload. If a supplementary protector opens, the receptacle does not work.

.Press button to reset. If supplementary

protector continues to open, contact Factory Authorized Service Agent.

! Power is still present at the 240 volt receptacle if CB2 and/or CB3 trips. Unplug power cord before attempting to service accessories or tools.

7 Optional 120 V 20 A AC GFCI Recep- tacles GFCI-2 and GFCI-3

GFCI2 and GFCI3 supply 60 Hz single-

4phase power at weld/power speed. Maxi- mum output from GFCI-2 or GFCI-3 is 2.4 kVA/kW. Circuit protection is the same as standard receptacles.
