Did a complete tune up. And welder runs good while on 120v.
But when welding it begins to surge. Up and down want to die but doesn't. I had to set it at setting 8-9. To weld 3/16 - 1/4" material. Usually I use setting 3 or 4. What could be going on. I read it could be the gas air mixture. Why would it had changed in a month or so.
