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 circuit breakers.
Reset GFCI receptacle.
No generator power or weld output. Disconnect equipment from generator power receptacles during start-up.

phase generator/receptacle RC5.
Place Process/Contactor switch in Weld Terminals Always On - Stick position (see Section 7-3).
Reset circuit breaker CB7(see Section 8-2).
Reset circuit breaker CB5 (see Section 9-8).
Check engine weld/power speed, and have Factory Authorized Service Agent adjust if necessary.
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 have Factory Authorized Service Agent adjust if necessary.
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.
