I was welding my car all day, rebuilding the inner wheel arch, everything was going fine. I had the clarke 90en with gasless wire on the lowest power setting (min 1). It was welding great and the suddenly it just stopped. I left it for a while thinking it was a duty cycle cut off. I tried the next power setting (min 2) and it started working again. I also tried the other settings (max 1 and 2) and they are fine. But the lowest power setting just won't move the wire feed anymore. I'm stumped.
