    Default Millermatic 251 control board

    Hello, I recently bought a millermatic 251, my issue is with my control board model number ( 220069 ) I noticed that the "R1" resistor (top-middle) had been knocked off, i cant find the resistor in the the machine was wondering if anyone could hook me up and give me the color code banding on their board or send me a photo of there board, so i can figure out the right resistor to put on, i looked all over the internet for a day and cant find even a single photo or diagram please help. Thanks much

    Try calling Miller or a repair center, email a photo of your board to them, they may be able to help you, it's worth a try.
