Hey guys Im a supper noob. I am completely self taught. 2 years ago I bought a 235. Its been absolutely flawless until today. It suddenly acts like the ground is not connected. Im MIG welding. Even if I go straight to the ground cable it just feeds wire but doesnt start. I checked my contacts and tried again. The wire stuck to the ground clamp and I heard a little sizzle/pop inside the machine. Anyone have any idea whats going on? Im guessing something failed internally.
