Running a 1-phase 240V welder off 3-phase 240V power receptacle?

Ken,

Thanks for a great answer and a proper solution. No ground IS a major safety issue.

I still would think there is 110volts somewhere in the place that will lead back to a 110/220 panel.

Minor, but it is actually 120/240. Power comes from a single phase transformer that is center taped, thus 120 X 2 = 240
