    Hello everyone,

    I just recently purchased a used C300 from a seller on ebay. As luck would have it, I was able to save the seller some cash and have him meet near where I was visiting family and friends. When I got it home and removed it from the crate, I noticed that the encoder potential-meter was broken (selects the different welding type 7018 6010 etc). I took apart the machine and believe that someone was inside the it before. I noticed some nuts and bolts missing, tape around the power switch and a few other things. How ever since this machine was made in 2014-ish and on the circuit board where the encoder sits has a date code of 2015. It leads me to believe that the board was replaced at some point. The part number for the board is 9SS28529-7. When I called up Mouser, they were asking for specifics about the encoder that I do not know. I was wondering if anyone else has had this problem with these encoders and what the solution was. Or if someone might have spare parts for sale. I purchased this machine for myself, but also planned to use it at a high school where I teach welding.

    Please advise,

    Mouser inquired about the following specifics on the encoder:
    # of detents or Pulses Per Revolution
    Pulses per resolution output type grey code
    binary coded decimal/serial
