Why don't you have an electrician wire the plug?

Here's a hint the black (hot line) and white (hot line) wires go to
the blades on the plug. Green is the ground/neutral wire in a three
wire 220 plug. It goes to the round pin.

Personally I switched the power lead on mine to a four wire feed
and
grounded it properly.

How the heck do you "properly" ground a 220v welder by switching to
a
four wire cordset?

A four wire cordset only adds a neutral to your two hot and one
ground
conductor and a 220v welder doesn't use a neutral. The welder comes
with a 3 wire cordset because that is all it uses. It's not like a
clothes dryer where there is a small 120v load which used to be
allowed to be carried on the ground and now requires a proper 4 wire
feed.

every welder I have every been around or owned has a 110volt cooling
fan
which needs a good neutral , and using the green wire for is is
asking
for trouble some time in the future, its a equipment safty ground
