I have a millermatic 211 and its input power is 120v/20A or 230V/25A. I have a honda generator an eb3000 with 2600w 120v/21.7A. It runs the welder but it seems the arc isn't as good as it should be. I used to have a millermatic 140 and used it with the same generator and it performed much better.
I was looking at getting a eb6500 generator with 6500w 250v/22.9A, to handle it better but its still underrated for the input. Any suggestions? I dont have 230v at my house
