What to do if the wire does not feed and the motor is not running in my ESAB MIGMASTER 250?

If the wire isn't feeding and the motor isn't running (drive roll doesn't turn) in your ESAB Welding System, set the wire speed dial to 10 and press the trigger. If voltage appears across the motor leads but the motor still doesn't run, inspect the motor gears and commutator areas. Also, with S3 ON, check if the voltage across terminals 1 and 3 is 24 VAC; if so, the switch and fuses are good. Check for 1K ohms across the POT outside terminals. Finally, check the board voltages to identify any malfunctioning speed control board.
