Hey Everybody!

I am in the process of wiring a 30 amp receptacle that has only three prongs (Like an old dryer plug) for my new Miller 211 that I should be getting tomorrow. In the past I have always hooked up one black (110) to one of the lower prongs, one red 110 to the other lower prong and then the neutral to the top center prong. Now I was told that would be wrong if I am coming from a sub panel (which I am, from by attached garage to the new shop). I realize I could just go out an get one of the new four wire receptacles but it still won't work with the three prong plug that comes with the welder ( it comes with a Neme 6.50 P . Help,

You need/have a straight 240v circuit. This requires only two hots and a ground. A dryer is a 120/240v circuit that requires a neutral.

You can run 10/2 cable and use the black and white as your two hots and the bare is the ground. You must re-mark the white as a hot wire with a permanent marker or similar method.
Be sure to attach the bare to the ground bar in the panel, not the neutral bar.
