Trouble
Remedy
Min or max CV weld output only.
Check position of Voltage/Amperage Adjust control and Process/Contactor switch.
Repair or replace remote control device.
Have Factory Authorized Service Agent check Amperage/Voltage Adjust Control and field current
regulator board.
B. Standard Generator Power
Trouble
Remedy
No generator power output at AC recept-
acles; weld output okay.
Reset receptacle supplementary protectors. Reset GFCI receptacle.
Check fuse F1, and replace if open (see Section 8-7). Have Factory Authorized Service Agent check inte-
grated rectifiers SR1 and SR2, resistor R3, and capacitor C6.
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 8-7). Have Factory Authorized Service Agent
check integrated rectifiers SR1 and SR2, capacitor C6, and the rotor.
Reset supplementary protector CB4. Have Factory Authorized Service Agent check integrated rectifier
SR1 .
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 re-
ceptacles.
Check engine speed, and adjust if necessary.
Check fuse F1, and replace if open (see Section 8-7). Have Factory Authorized Service Agent check inte-
grated rectifier SR2, resistor R3, and capacitor C6.
Have Factory Authorized Service Agent check brushes and slip rings, and field current regulator board.
C. Three-Phase Generator Power
Trouble
Remedy
No or low output at three-phase gener-
ator/receptacle RC5.
Reset supplementary protector CB1 (see Section 8-7).
Check engine weld/power speed, and adjust if necessary (see Section 8-5).
Have Factory Authorized Service Agent check brushes and slip rings, and field current regulator board.
High output at three-phase generator/
receptacle RC5.
Check engine weld/power speed, and adjust if necessary (see Section 8-5).
Have Factory Authorized Service Agent check field current regulator board.
Erratic output at three-phase generator/
receptacle RC5.
Have Factory Authorized Service Agent check brushes and slip rings, and field current regulator board.
