I'm having an issue with my Clarke MIG 100e Mk2 welder. The issue is that when I stop welding, let go of the trigger, the wire quite often will melt onto the end of the copper tip. Sometimes, this is quite easy to sort out, let it cool down and a pair of pliers will snap the blob off the end, but quite a few times it requires a lot more stripping down, filing the end of the tip until it releases enough of the wire for it to release itself. I have one tip that has wire stuck in it and is now effectively scrap as I can't get it out.
I've recently replaced the liner and this seemed to improve things for a while, but this afternoon I've stripped the thing down so many times, wasted around 4m of wire because when it sticks, I try to feed the wire through and that causes it to push into a loop either between the feed wheel and the liner, or between the other end of the liner and the rigid section of the handle. Thus I have to stop, cut the wire, remove it, feed a new piece through, then try a weld and it melts back again and I have to do it all over again. For some reason, the wire won't feed directly from the end of the liner into the rigid part of the handle - I have to pull the liner out, feed some wire through, manipulate it into the short liner in the end part, then put it all back together.
When it's welding, it seems to be perfectly OK - other than stripping the thing down several times, it's done the rest of the job this afternoon just fine. This is a welder that was put out for scrap during one of those lockdown clearouts, but it's performed quite well since I got it. It's almost been on the scrap pile several times this afternoon, but I couldn't find my old welder to finish the job off - the latest problem happened while I had less than an inch of weld to do.
Those things are irritating, and perhaps point to me not fitting the liner quite correctly, but it wouldn't matter if the thing didn't keep melting the wire against the tip. Can anyone suggest why it might be doing this sometimes?
