I am just in the process of getting some electrics sorted to run my old Oil Cooled welder. Fiddling with it today, it seems that the volts/amps selection lever wont turn far enough anti-clockwise on the dial but turns too far clockwise. The pics below show how far I can turn the lever clockwise and anticlockwise and let it drop down to engage. I have inherited this from father in law and havent used it, so I am not sure what the fix is or what might have caused it (presuming this isnt normal?)?
