I took the machine to the repair shop and it turned out the wire had broken from the slip ring where the brushes touch. The repair guys told me that I con solder it together but Ive tried and it keeps breaking off. Do you guys have any suggestions on how to do it? ( machine is so old I cant find parts for it)
Reply:I have 3 bobcat 225's. 2 that run and one for parts. The first one i bought did the same thing you're talking about. I had it soldered on at a electric motor shop. It lasted for about 100 hours or so. I then soldered in some braided wire like off a motor brush so it had some flex and then to the armature winding. Then i taped and varnished it up good so it wouldnt move and its still lasting. Another Hobart i worked on broke off near the slip ring too but wasn't long enough to solder to the slip ring so i ended up pulling that wire out of the armature to make length and was able to solder it to the slip ring then. One coil is one wind smaller than the other one but they haven't had any issues with welding or generating 120 volts with it. It was either try that or scrap it. If you're replacing an armature it's almost better to find another machine. I thought about rewinding it but that would be really time consuming so in my case on the bobcat's it made sense to swap parts around. I see older bobcat's pop up for sale once in a while not working for around $400 or so.

Reply:Okay so I soldered it back together but I didnt use the flux cleaner and it seems to be sticking now. I used epoxy and loom tape. It seems to work haded running until the tank went empty and it still works now Im not getting the full voltage out of the outlets or the welding leads
