    As long as your extension cord is 10 ga or bigger you are good to go! Nicely done!

    National Electrical Code Is adopted by each state with or without amendments. In every state I am aware of, all equipment used must be listed. What this means to us is: if it ain't mass produced any liability falls to you. When you cut a listed (UL or CSA) cord nothing bad better happen, or it's your fault.That said, will anything bad happen? You better know the answer! I often make up equipment to solve a problem, I know that each time I do I accept liability for not only what I do, but anyone else later does with it. I alter a cord, someone then shuts it in a garage door, a court of law is likely to rule that had I not altered the cord, Dumb Dumb wouldn't have been using it to do something dumb, wouldn't have shut it in the door! After all, Dumb Dumb has no insurance or assets, what would the point of blaming him?

In mild cases this can be addressed with welders equipped with "auto line" style automatic voltage adaptation. In less extreme situations more current in a supply line means more heat produced, and more voltage loss. As many welders can run on 200 volts, voltage loss isn't always debilitating. Voltage loss means heat! heat produced in 2 minutes can often cool while a 20% duty cycle welder cools.

    IT IS STILL ESSENTIAL TO CALCULATE ALL COMPONENTS OF A WELDER SUPPLY AND CAREFULLY INSTALL OR CHECK. A BAD CONNECTION MEANS A FIRE USUALLY IN A LOCATION YOU WON'T KNOW ABOUT UNTIL IT'S TOO LATE.

    the numbers seem right to me....got them from the literature and manuals...
    remember.. both machines are inverters so they are going to draw considerably less power than the transformer machines we are used to..

    it does go to show how much more efficient the inverters are... and power factor considerations on the transformer machines that we don't need to worry about on an inverter..

    Here is a video that gives a lot of good general info on home garage welding.. (fair amount of sales pitch ... but a lot of good info as well)

    Is the 211 an inverter? I always thought the multimatic was the first small all in one mig to be an inverter. And that's why it's so much lighter.

    I think I may have been mistaken I had read in a few places that the MM211 was an inverter.... BUT... other places say transformer.... and at 74 pounds... I am begining to suspect it is a transformer/SCR controlled machine...

    have been unable to download the manual... so I will defer that to somebody who knows for sure....
