Just start a new thread with your questions and he will probably join in the discussion. There are a number of other really smart guys here also, so ask away. Great group here, that has helped me out several times, in one case saving me from blowing an expensive board in my Trailblazer. And I now have an avatar thanks to H80N!

    Miller support is why I have Miller welders. Other people make some good products, but I don't think any other big guys provide help like Miller. There are no doubt some who would take issue wth that; everyone's entitled to their opinion, but that's mine. Also lots of good support reports on HTP (usaweld.com). Good place to look for supplies, great people.

    Thank you, Aeronca41! That's great to hear. We're always happy to help.

        Made a popping sound as the input mod pooched itself. So replacing PC5 will do nothing until the mother primary board and its mods are replaced

          I changed the primary board with the resistor that blew. Cruizer is it common for those Semikron mods to fail if the primary board fails? They seem isolated and feedback failure doesn't look likely. Do you have a data sheet on those mods? Thanks, Mike

            One thing I forgot to mention was that there was about a 5 second delay from when I powered up till the pop, maybe longer. In addition to fixing my machine I'm more curious as the the root cause. I'm kinda a need to know guy.

              Well, yes as the unit has to determine the input voltage BEFORE the regulators in the Mods. yes, your input Mod is blown. . Email me at [email protected]. Perhaps I can throw you the Preinspection for the unit BEFORE you start throwing useless parts at it.
