SECTION 7 − OPERATING AUXILIARY EQUIPMENT

7-1. Generator Power Receptacles

803 750-B / Ref. 211 362-A
!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 7-3 for 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.
5 Supplementary Protector CB2
6 Supplementary 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-
phase 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.
If a ground fault is detected, the GFCI Reset
button pops out and the circuit opens to dis-
connect the faulty equipment. Check for
damaged tools, cords, plugs, etc. connected
to the receptacle. Press button to reset re-
ceptacle and resume operation.
.At least once a month, run engine at
weld/power speed and press Test button
to verify GFCI is working properly.
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
