Plasma cutter wiring?

[chromeyellow]

I moved to a new house a month or so ago and had a nema 6-50 plug installed so I could use my Miller 211 on big boy voltage. How do I hookup my plasma cutter to the plug? The colors on my Cutskill 35a are blue-brown-green/yellow not black-white-green. I had this hooked up to my dryer but took off the plug for the guy to use for his dryer and hell if I remeber or can find the instructions after moving.

Green is ground U shaped prong. The other two (blue and brown) are the hots and it doesn't matter which ones you hook to the two 2 flat prongs.

really pattenp? wow, that just seems funny. But i'm not an electrician (guess I wouldn't be posting on GJ if i was though!)

Why do you feel that is funny? With 240V there is no neutral so both wires are hots on different legs. Since both wires are hot it doesn't matter which wire goes to what prong. You get 120V by splitting the legs with the use of a neutral.

The blue/brown/green with yellow tracer color scheme is an IEC (European-based international) standard. When used on 120V here in the states, the blue is the neutral, the brown is the hot/line, and of course the green one for ground. When used on 240V, the blue is used as the second hot wire. Most three-wire cords used in the states on 240 are either the IEC as above, or the old familiar black/white/green. The white gets used as a hot on 240V in flexible cords.

Those are Europeon color codes, Brown is hot, Blue is neutral, yellow/green is the grounding / "earthing" conductor, but a line to line 240V connection is fine.

Why do you feel that is funny? With 240V there is no neutral so both wires are hots on different phases. Since both wires are hot it doesn't matter which wire goes to what prong. You get 120V by splitting the phases with the use of a neutral.

Different phases? It's single phase different legs would be more accurate.

You're correct. I don't know why I said phases.

I corrected my terms.

 

[pattenp]

If you want to be politically(color) correct put the blue on the wide prong.

pattenp- idk much about home electrical systems so it just seemed funny to me that it doesn't matter

Thanks everyone

 

[chromeyellow]

Woohoo!

 

[pattenp]

Of course it does. You didn't have any doubts did you?

Of course not!

Thanks for the help, I appreciate it!
