  • Hobart Hefty and stupid Bob trick, HELP!!

    OK, I took my perfectly working Hefty feeder to work to hook up to our Miller single phase stick welder. I wanted to add a platform for the bottle of C-25 so I put it in CC mode, hooked it DC electrode positive and did all the normal stuff I do at home on my POWCON. BUT, I hooked the ground, the voltage sensing clamp to the welder as that was what i was to be welding on. It immediately blew the big 1/8 amp 250 volt slow blow fuse. I replaced it, hooked it to another piece of work unrelated to the welder and all I get is wire feed. I get no arc and no gas solonoid action? I get the same with my POWCON now at home. Any idea what fried? How to check it? MAC????

    No contactor

    Remove the wire spool and take off the inner cover to expose the circuit board(s). The smaller one is the contactor drive and solenoid driver. There should be a fuse on it if my memory is correct.
