Check whether jog switch or wiring is stuck active.
Fault route
MIG200DL Wire Feeds Continuously Diagnostic
A MIG200DL continuous wire-feed route that separates stuck command inputs from stuck feeder output.
Quick Answer
If MIG200DL wire feeds continuously after power-on while other functions appear normal, check the jog/trigger signal path to P13 and the power-board command state before replacing the motor.
- Continuous wire feed can be caused by a stuck jog/trigger signal or a board-side output stuck active.
- The feeder motor is usually not the first suspect if it runs continuously.
- Separate input command stuck from output command stuck.
Use this page when
- Wire starts feeding after power-on without valid trigger/jog command.
- Other machine functions are mostly normal.
- P13 and feeder-output behavior can be checked.
Do not use this page when
- Wire does not feed at all.
- Trigger no-response is the main symptom.
- Machine is completely dead.
MIG200DL continuous-wire-feed route
Separate stuck input command from board-side output fault.
Check torch trigger signal path for stuck input.
Identify whether the board is receiving a false command.
Check whether feeder output remains active without command.
If input is normal but output stuck, inspect power-board feeder control.
Continuous feed evidence table
| Evidence point | Expected / abnormal evidence | Repair direction |
|---|---|---|
| Jog switch | Stuck jog command can force feed. | Repair/replace jog switch or wiring. |
| Torch trigger | Stuck trigger path can mimic commanded feed. | Inspect torch switch and P13 line. |
| P13 signal | False input command present at board. | Trace input harness/switch path. |
| P14 output | Feeder output active without input command. | Inspect power-board feeder output section. |
| Feeder motor | Motor runs because it is being powered. | Do not replace motor unless mechanical fault is separately proven. |
