    Default What generator would be good for a mm200?

    So I have a MultiMatic 200 and I'm wondering what generator I get to run my welder at MAXIMUM performance? Got any suggestions? Thanks guys!

    Considering the input power needed to run your machine, I would say that a 3000 continuous watt generator would be plenty. As for the brand, that would depend on your budget.

    A MM200 is pretty hefty, its a 50A service machine. I would think 8 K or better.

    He's talking about the new multimatic 200 not the old millermatic 200. The MM200 threw me off also. Just shows some of us are getting older.

    That's still way too small for the multimatic

    3000/240v= 12.5 amps

    The Multmatic draws 18amps at rated 150 welding amps Mig and 20 amps Stick

    20amps x 240v = 4800 watts continuous so yer looking for a genset that is around 5500watts

    Sorry about that. You are definitely right about the wattage. I was stuck on stupid for a minute and was estimating from my head and posted the wattage on the 120V side instead of the 240V.

    As for the brand, I have always went with the Generac and have never been disappointed.

    In my opinion, Generac and Honda are at the top of the list.

    Broccoli is right on point. Also you gotta think if you are gonna run lights off of it, tools etc etc etc. I would go at least 7500.

    I'm surprised somebody hasn't already suggested an engine drive weld machine.

    A bit more weight and price but you can open many more doors by going that route.

    Not to mention a miller or lincoln gas welder costs less than an equivalent Honda. Also to be noted is engine drive welders advertise continuous watts not peak watts like generators
