! If unit does not have GFCI recep- 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.

2120 V 20 A AC Duplex Receptacle RC2

3120 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.

6Supplementary Protector CB2

7Supplementary Protector CB3

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

.Press button to reset. If supplementa-

ry protector continues to open, con- tact Factory Authorized Service Agent.

GFCI Receptacle Option

8120 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- nected to the receptacle. Press button to reset receptacle and resume operation.

! Power is still present at the 240 volt receptacle when only one circuit breaker trips.

Unplug power cord before attempt- 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 kVA/kW
