Hi, I have a Sealey Mightymig 140xt & it has stopped feeding wire. From the start - I bought a new torch,fitted it and then I had no wire feed. All I did was disconnect the existing wires and plug in the new ones. I started looking online and came across a few threads on this forum with what sounded like the same issue, most of which pointed to either the feed motor or the wire feed pcb. I purchased a new feed motor first but the problem was the same. So I next purchased the pcb, £82 ouch!, and the problem is still the same. When I pull the trigger you can hear the relay and the sound you get when the the wire is stuck. Any help will be much appreciated.
