  • 14 pin connector?

    What is the most common use of a 14 pin connector?
    I have one on my TrailBlazer that I assume is for running a wire feeder?

    But, I also have a MM250 with the 10 pin module for running the 30A spool gun. The 10 pin module also has a 14 pin connector. What would this be used for on the MM250? Just wondering if I have some hidden capability that I should be aware of.

    The 10 pin hook up would be for an older model.I would say that Miller standardized there plugs about 10 - 15 years ago or maybe longer and even though you have a 14 pin amphenal does'nt mean every accesory uses all 14 pins but its a universal cable.
    With your Trail blazer you can run your spool gun, I have an older gun so mine just plugs straight in, the newer guns need a W-C 24 controller that go between the gun and the power source.
    I also have a S22P-12 Suitcase feeder that uses the 14 pin cantactor cable.
    The fuction of the cable is I can adjust the wire speed feed at the feeeder and the voltage controll.
    Your Trail blazer also operates a HF 251 High Freq box used for tig welding aluminum that runs through the cabe.
    Hope this helps. Portable Welder.

      The idea of the 14 pin is that you can run virturally any Miller or competitors accessories on your machine, and/or have a remote control.

      It's a 20-27 series amphenol if your interested

      As for the 10 pin, no hidden agenda, it's just fo running a 15, or 30A gun and thats about it...
