I AM NO ELECTRICIAN

But I wired my 220 TS 10 years ago. Mine has 3 wires. 2 leads and a
neutral, not a ground.

No, there is no neutral for a 220 (US, not Brit); the third conductgor
is a ground. You're confusing the use of the ground as neutral for
the 110V circuit of a 3-wire dual voltage hookup (electric range
range/dryer for example) as making it a neutral--it isn't.

Are you sure yours is not wired for 110? From what I understand
more modern wiring set ups are 4 wire. 2 leads, a neutral and a
ground.

Again, that's only for dual-use--the TS doesn't have the 110V load so
no need. Recent NEC requires the neutral rather than shared but again
there's no neutral for 220V only.

Might want to consult a qualified electrician on the matter.

OP did have the circuit run by an electrician he says -- as somebody
else noted, all he needs is a 3-wire cordset to update the old 2-wire
one in the most convenient manner to add the ground.

That is right. You only need a neutral when you need dual voltage as in a
dryer or stove. 240V (no longer 220 volt) only equipment such as motors only
need the two hot wires and a ground. Use the specific plug and receptical
for 240 volt and the rated amperage, better still, use a twist lock plug and
receptical (again the correct type for the voltage and amperage) if the wire
trails across the floor so that it doesn't get pulled out.
