OM-4428 Page 60
Trouble Remedy
Low CV weld output. Set Ampere Range switch to highest range.
Increase Voltage/Amperage Adjust Control setting.
Min or max CV weld output only. Check position of Voltage/Amperage Adjust control and Voltage/Amperage Adjust switch.
Repair or replace remote control device.
Have Factory Authorized Service Agent check Amperage/Voltage Adjust Control R1, and field current
regulator board PC1.
C. Standard Generator Power
Trouble Remedy
No generator power output at ac recep-
tacles; weld output okay.
Reset receptacle supplementary protectors.
Reset GFCI receptacle.
No generator power or weld output. Disconnect equipment from generator power receptacles during start-up.
Check fuses F1 and F2, and replace if open (see Section 9-8 or 10-9). Have Factory Authorized Service
Agent check integrated rectifier SR1, capacitor C9, and the rotor.
Reset supplementary protector CB12. Have Factory Authorized Service Agent check diode D1 .
Have Factory Authorized Service Agent check brushes and slip rings, and field excitation circuit.
High output at generator power ac re-
ceptacles.
Check engine speed, and adjust if necessary.
Have Factory Authorized Service Agent adjust generator power field current resistor R3.
Low output at generator power ac recep-
tacles.
Check engine speed, and adjust if necessary.
Check fuse F1, and replace if open (see Section 9-8 or 10-9). Have Factory Authorized Service Agent
check integrated rectifier SR1, resistor R3, and capacitor C9.
D. Optional Three-Phase Generator Power (CC/CV Models Only)
Trouble Remedy
No or low output at optional three-
phase generator/receptacle RC5.
Place Process/Contactor switch in Weld Terminals Always On - Stick position (see Section 7-3).
Reset supplementary protector CB7(see Section 8-2).
Reset supplementary protector CB5 (see Section 9-8 or 10-9).
Check engine weld/power speed, and adjust if necessary (see Section 9-6 or 10-6).
Have Factory Authorized Service Agent check brushes and slip rings, and field current regulator board
PC1.
High output at optional three-phase
generator/receptacle RC5.
Check engine weld/power speed, and adjust if necessary (see Section 9-6 or 10-6).
Have Factory Authorized Service Agent check field current regulator board PC1, and PC1 voltage
feedback circuit.
Erratic output at optional three-phase
generator/receptacle RC5.
Have Factory Authorized Service Agent check brushes and slip rings, and field current regulator board
PC1.
