    Powcon 300SM output cable connectors question

    Hello, I am looking for some information on the output connectors on a Powcon welder. It looks like it has the twist lock type connection for the output, but not sure which connectors to buy, since it did not come with any. It was wired for 460 3 phase when I bought it, but wired it to 240 single phase now. I am getting voltage at the output and am itching to try it out. I have the LENCO 4 MPC connectors on my other welders and those are too big, so any help would be appreciated. I was going to order some LC-10 and LC-40 to see if they fit, but figured I would ask to see it anyone here knew for sure what to get.

    Thanks,
    Chris

    Thinking that they ar 50mm Dinse. Pretty common. Better double check though.

    They are the lenco lc-40 on my unit, and the 2-mpc Tweeco also work. I ordered the 2-af connectors so I could move the ln-7 feeder back and forth between welders.
