How do I wire a 230v 21amp welder using a 230v 30amp dryer circuit
I have a new welder (230v 21amp) with a NEMA 10-30P cord. I also have an electric dryer (230v 30amp) which attaches to a NEMA 10-30R. The dryer circuit has two hots and a common, no ground. The welder has a hot, common and a ground wire. How would I set up connections so the welder and the dryer can use the 230v 30amp circuit from the panel (obviously only one devise could be operating at a time)?

Above assumes there is not continuous metal conduit to the breaker box.
