tacles, use GFCI-protected exten-
sion cord.
. Generator power decreases as weld
current increases.
Set Fine Control R1 at 10 for full gen-
erator power.
1 240 V 50 A AC Receptacle RC1
RC1 supplies 60 Hz single-phase power
at weld/power speed. Maximum output is
11 kVA/kW.
2 120 V 20 A AC Duplex Receptacle
RC2
3 120 V 20 A AC Duplex Receptacle
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.
4 240 V 50 A AC Receptacle RC5
RC5 supplies 60 Hz single-phase power
at weld/power speed. Maximum output is
11 kVA/kW.
5 Supplementary Protector CB1
CB1 protects receptacles RC1, RC2,
RC3, and RC5 from overload. If CB1
opens, the receptacles do not work. Place
switch in On position to reset.
6 Supplementary Protector CB2

GFCI Receptacle Option
8 120 V 20 A AC GFCI Receptacles
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 Re-
set button pops out and the circuit opens
to disconnect the faulty equipment. Check
for damaged tools, cords, plugs, etc. con-

ing to service accessories or tools.
. At least once a month, run engine at
weld/power speed and press Test but-
ton to verify GFCI is working properly.
Combined output of all receptacles limited
to the rating of the generator.
Example: If 20 A is drawn from each 120
V duplex receptacle, only 26 A is available
at the 240V receptacle:
2 x (120 V x 20 A) + (240 V x 26 A) = 11.0
