SOURCE: Toolex 140 mig welder, wont feed wire.

You may have the scew settint your wire tension set to tight. Try loosening the tension and if that doesnt work check the eletrical wire that supplies the power to the roller and make sure it hasnt become disconected.

Relay/contactor is stuck closed.

SOURCE: Wire feed runs at maximum speed

Ensure the set is upluged, then check coninuety? across centre tag and the left tag then the right tag, if this checks out OK then check the resisters close to the center tag. potentiometer are cheep enough, get a replacement from Tandy or RS spares.

SOURCE: Wire feed does not stop. Not the trigger.

you have a problen with the electronic circuit.
Where are you?. Perhaps I can help you.

SOURCE: I have A solar mig

check for circuit breaker by drive motor, it may be the pc board.
