  • mm 251 on a generator

    can u run a 251 on a bobcat trailblazer or pro 300 if not
    will a guardian system work

    To run a 251 off of a genny, you will need one that is capable of producing around 14Kw.

    I get this figure by multiplying the full load amps of the welder (54Amps I think)by 240 volts.
    This gives you a figure of 12960Watts. add another 2kw as a safety margin and this is what you will need to provide to the welder in order to run the 251 at full load. If you are running at less than full load, you could get away with a smaller Genny but its not a good idea.

        Hi,
        The Millermatic 212 models and under will work off of a Bobcat and Trailblazer, unfortunately, the MM 251 will not work very well. Because it uses SCR's, it requires higher amounts of "peak" currents than our generators can supply. From what I've seen of Guardian generators, they will not power that machine either.
