Hi All, I just bought a used Sears Craftsman 113.201371 Welder. I'm curious about the current adjustment, it doesn't have a tapped transformer. It has a slider that (from the outside) seems to move into or out of a core. Does anyone have more info regarding how the adjustment varies the output? I understand tranformers and inductors, just trying to end my curiousity before I open it up to see how it works. Thanks, Mike
