Hello there, i just picked up an older model sealey supermig 195 from a local guy, continuining on with my strange current obsession with buying broken migs
I was told the problem with it is that you'll be welding along, and the wire feed will slow down gradually and stop (gradually as opposed to the spot timer being on and it stopping dead i'm assuming)
he took it to a local welding place and they told him the feed motor was probably bad or tired or something along those lines, but i dont think they actually checked it rather just pointed at that being an obvious culprit
now when you hear that sorta thing i'd expect it to be something mechanical binding the wire up, dirty rollers, bad liner etc, but having got the thing back home, left it exactly as i picked it up aside from putting my own wire in it, i cant seem to get it to misbehave, the liner in the torch is definately on the crispy side up by the torch head and who knows what sorta angle he had the lead bent round at, but i've done a dozen welds maybe 6" long (longest piece of scrap i had immediately to hand) listening to the feed motor the whole time and it seems to work fine, isnt the smoothest or most powerful feed setup i've used but it seems to sound consistent, power setting 4 of 6, wire speed a touch over half way.
So before i service it and put it down to dirt, poor machine set up or a dodgy consumable, my question is this, do you guys know of anything electrical that would cause this sort of symptom? something on the pcb or involving the aux transformer, anything that would have the affect of gradually slowing the feed down to a stop, i've seen brushed motors do this kinda thing when the brushes get worn but i dont know why it wouldnt do it for me, so far atleast, i'll have to use it more and see what happens, havent even taken the side panel off yet and given it a once over or cleaned it or anything, its exactly as i got it currently, any tests i should do or ways to prod it into being naughty?
Thanks as always! P's.
