I have a Lincoln ProMig 180. I used to be able to weld almost half a chassis on heat setting D without stopping. Then one day it started hitting thermal protect mode really easily. It would only make it through about 4 tube joints before hitting thermal protection. My shop is dusty so I took it apart and blew it out really good. A bunch of metal dust came out from the cooling fins. I closed it up and its a little better now, I can get through about 8 joints, but nothing like it used to be. The fan is running like it always did. I'm out of ideas.
