I got an OOOPS with my long time Tombstone arc welder. At one time I thought I would replace the old arc welder with a lincoln 175 mig,,,but after many spools of wire,,i really still like that old arc machine,,,!!

 I was doing some work on my car trailer and noticed that the insulation on both the work and ground cables coming thru the front of machine were just about frayed in to and fixing to start arcing to the metal box,,,,!!

 I took the panels off that gave me access to the work and ground cable connections and made new ends after cutting back the frayed cables,,,Man,,that was close and most likely "SAVED" the welder and prolly me too,,,!! Assembled the panels and gave it a test run and,,,,and,,,,you cannot hardly turn the heat selector knob in front,,,!!  I did not move anything on that part of welder and can't figure why as it had worked great brfore I changed the cable ends,,,,????

 Finally used a flat screwdriver and wedged behind the selector knob and got it to switch but hung up soon as I removed screwdriver,,,,??

 What the hey,,,??
