Fuse F2

 

 

F1 and F2 protect the stator exciter winding

 

 

from overload. If F1 opens, weld and gener-

 

 

ator power is low or stops entirely. If F2

 

 

opens, weld output is low or stops entirely.

 

 

4 kVA/kW generator power is still available.

CB4 protects the welding arc drive (dig) cir-

 

 

cuit. If CB4 opens, electrode may stick to

 

 

the workpiece more frequently during low

 

 

voltage (short arc length) conditions. CB4

 

 

automatically resets when the fault is cor-

 

 

rected.

 

 

CB5 protects the 24 volt ac output to remote

5

receptacle RC14, and 24 volt output to field

current regulator board PC1 (CC/CV mod-

 

 

els only). If CB5 opens, weld output and 24

 

 

volt output to RC14 stops. On units with op-

 

 

tional three-phase generator, power output

 

 

at receptacle RC5 also stops if CB5 opens.

 

 

CB6 protects the 115 volt ac output to re-

 

 

mote receptacle RC14 (CC/CV models

 

 

only). If CB6 opens, 115 volt output to RC14

 

 

stops.

 

 

CB10 protects the engine battery circuit. If

 

 

CB10 opens, the engine will not crank.

 

 

CB10 automatically resets when the fault is

 

 

corrected.

 

 

CB11 protects the weld control circuit. On

 

 

CC models, if CB11 opens the max OCV

 

 

circuit does not work and open circuit volt-

 

 

age is variable at all times (see max OCV

 

 

note under Weld Controls in Section 6-2). If

 

 

CB11 opens on CC/CV models, weld output

 

 

stops (generator power is still available).

 

 

CB12 protects the field flashing circuit. If

 

 

CB12 opens, the generator may not excite

 

 

at start-up and weld and generator power

 

 

output may not be available.

 

 

CB13 protects the engine control circuit. If

 

 

CB13 opens, the engine does not crank.

 

 

CB14 protects fuel solenoid FS1. If CB14

 

 

opens, the engine does not start. CB14 au-

 

 

tomatically resets when the fault is cor-

 

 

rected.
