I have a 3kw military inverter generator(MEP 831A) that is supposed to provide 31A @ 120V. On a static load it does real good. If I try to use my Lincoln 140C welder(120V), the disconnect on the generator often opens. Guessing the inverter generator doesn't like the instant short the welder provides any time you have an oops with the wire distance.

Something to test before you buy an inverter type generator.

I have a 220V Miller Thunderbolt AC/DC stick welder. I was looking at the specs on it to understand what amperage it needs to run properly. Here's what I found:

It says "Amps input at rated output 230V: 47.5" So, is it that the amps needed? What happens if the power source does not provide that amount of amperage?

This generator shows it has a 240V/50A outlet.

Is that what is needed for the welder to work properly?
