Does anybody have any experience with this pedal on a PP256. I for some reason have no amperage control now tig welding, its either not welding or its full bore to the set amperage. I bought the SSC foot pedal through Evelast and even had ssc look at the pedal and theres nothing wrong with the pedal. I had the same problem before and it ended up being something burnt up on the welder the first month I had it. Any helps appreciated
