- Power source powered, the wire feeder motor does not work.
WIRE FEEDER MOTOR (5) TEST.
q
Control board (42), connector J2, terminals 1 (+) and 2 (-) = 0 / +28 Vdc approximately
adjustable using the knob (D), with start button pressed.
NO
YES
♦
Check the wiring between J2 control board (42) wire feeder motor (5).
♦
Make sure there are no mechanical impediments blocking the motor.
♦
Check the motor rotation direction; if incorrect, reverse the wires on the terminals
of J2 on control board (42).
♦
With the power source off, temporarily disconnect the terminals of the wire feeder
motor (5) from the connector J2 control board (42), and check the resistance
between the motor terminals left free. Correct value = approximately 1 ohm
(resistance of the motor winding). If >Mohm (winding broken), replace wire
feeder motor (5).
♦
Replace the wire feeder motor (5).
♦
Make sure the wire feeder motor start command is present by carrying out the START
COMMAND TEST, par. 3.3.3.
♦
With the power source off, temporarily disconnect the terminals of the wire feeder motor (5)
from the connector J2 control board (42), and check the resistance between the motor
terminals left free. Correct value = approximately 1 ohm (resistance of the motor winding). If
0 ohm (short-circuited), replace the wire feeder motor (5) and control board (42).
♦
See CONTROL BOARD (42) POWER SUPPLY TEST, par. 3.3.1.
♦
Replace the control board (42).
