At work I will be needing 240v 1ph power for my plasma cutter, but all
the panels are 208 3ph. The machine specs say 200v to 240v so all I
should need to do is have the proper outlet installed. Does that
sound right to you guys? It seems a bit on the low side to me.

Many welders are now made for single and three phase pending a different
cable installation inside...
Can you change cable and be in like flint ?
Otherwise your electrical type can install a transformer.
Since you handle 200 ok - a single leg of 208 seems ok to me.

Your plasma cutter may work. My Hypertherm 1000 will lock onto many different
voltages, 3 phase or 1 phase.
If it does require single phase voltage then you can start with any two leads of
your 3 phase power and use a transformer to change the voltage to what you need.

Dan,
Make certain that there are no neutral to ground references within the unit.
You can use an ohm meter to do this. If you find an open circuit, then
making a phase to phase reference for power will not be a problem. I do not
believe the lower RMS voltage will make a difference.

208 is on the low side of the range from 200 to 240, but it is well
within the specified range so it should work OK.
