I have a everlast 255 ext, I have been getting roughy starts on this machine. Low amperage it studders and then initiates the arc. I was watching the tungsten close last night and when I start, it arcs from my tungsten to the work piece from all over the tungsten till I push the peddle and get the amperage up.
Could it be a grind angle or? Sharpie style grinder with a Milwaukee power unit
