The maximum voltage available to me is 230 volts at 60 hertz. Abroad, it would be 220 volts, 50 hertz.I consider purchasing a Millermatic 211 with a spool gun.I am aware of penetration issues for this plate thickness, but I am told proper joints selection preparation and pre-heating would compensate. Is that really so? The Miller chart shows only 4043 feed wire while I would need 5356. Why is that? Their calculator do not recommend globular welding, only spray in flat position(!) at welding voltage in excess of the machine capabilities...Did you ever try welding 1/4 inch 5086 aluminum plates with a Millermatic 211? What settings did you use? How was it?Would you recommend that acquisition for my application?Thanks!
    Don't you have a pair of 8D Batteries onboard....??

    in series they make a beautiful 24VDC CV supply... all you need to do is hook up a spoolgun..

    way more horsepower than a MM211

    Biggest problem might be carrying and refilling your Argon bottle..

    I think you will be okay welding 1/4" with preheat, However, I only have the big spool gun that I run off a few different machine and 1/2" plate is not a problem.
