Will my metal welder work ok?
My oven/range has a power outlet that reads on it: 125/250V, 50Amps. It has four prongs, three vertically oriented flat ones aligned as a triangle with the center one lower than the other two, and a fourth one top center that's round. My breaker box shows a 50Amp breaker for it. The welder says it's a MIG 170, 240V AC, 20Amps,single phase, 60Hz (Harbor Freight).
I think the power I have is actually 220V but I'm not sure. If I do only have 220V will the welder only draw as much voltage as is asked by it - that is, if I only crank it up, say 3/4 of the way, will it draw less than its rated 240V? Or is that 240V just a maximum rating and it should run ok with 220V? It would seem odd that they would sell a welder that won't work for the power their customers would have by default without modifications.
Also, where can I get a double socket for that outlet with one having an extension so I don't have to pull out my oven every time I need to weld something?
