  • Dynasty 300 question

    Hi all,

    New to the site. Have been reading it for a while. I have the opportunity to buy a used Dynasty 300 SN LA160307. Won't get a chance to try it out. Infomation on it says the HF start doesn't work. It will scratch start supposedly. Only other comment is - it will need a new HF generator. Any thoughts on what that might mean - or does that make sense for this type of welder.

    It is currenlty owned in a university lab for students to use. I am trying to understand what I might be looking at for repair costs before I make a bid on the machine. I will just be using it for my shop at home.

    Thanks for any help.

    You'll need a HF board. They're around $400.
    You might want to check the HF points. It should be at .010. Need to pull the cover to check.

      I love buying non working items from goverment agencies....Lots of the time it is something simple. Most time they are to lazy to fix it.

          Might even be more simple than that.

          Being that it is in a school, it wouldn't surprise me if someone got into the microprocessor settings and goofed them up.

          First thing I would do when I got it home was do a SYSTEM RESET. Then start taking your checks.
