  • how to test TIG foot pedal?

    i was given an older Miller foot pedal with a 14 pin connector on it. i was told by the guy that it "acted funny" and he replaced it with a new one.

    my question is how can i test this foot pedal with a multi-meter to see what its problem is? what kind of values should i see and what pins should i test across. also, what is the name of the 14 pin connector? the outter threaded sleeve is cracked and doesn't hold it into the machine firmly.

    thru a little research, it appears that it is basically a potientiometer in there that varies resistance with the pedal movemant.

    any help, information, or ideas will be greatly appreciated!

    Welcome to the forum Jeepnmatt

    It seems to me that what usually goes wrong on the pedals is the switch that the pedal hits down onto.

    But what do I know I just weld.

    Good luck Bud.

      JEEPNMATT..........Indeed there is a micro switch inside, and a potentiometer.........Most likely 2k but when you get inside it should be marked on it.............The value........ it should be linerar and smooth.......... The micro switch is just on/off by depressing the pedal down.............Everything else is wireing..........

      See if you can find the part number on it........... Most parts are still available....................Rock..........
