Any help is appreciated.

I have a 50 amp breaker. I have #6 AWG wire with 3 conductors and a
ground wire. The welder has 2 black wires and a green wire. The
sheething on the welder's wire says 'green conductor for ground only'.
The plug I have has 3 flat blades and says 'for non-grounded use
only'.

I'm confused. Do I wire up the breaker with 2 hots, a neutral, and a
ground and wire the receptacle with 2 hots and the ground? I was
originally figuring I would use the 2 hots and a neutral from the
breaker to the receptacle.

What am I missing here?

Any help is appreciated.

Crap. Thanks for the information, though. I was afraid of that.

But, I can still use my same wire, right? I just don't use the third
conductor, only the two hots and the ground?

You have the wrong plug / receptacle. A 240V welder doesn't use a
neutral connection. You need a 240V 50A grounded plug / receptacle.

Your confusion results from three different 'standards' over the years.
The earliest 240 wiring had two hots and a neutral (red/black/white).
Later welders (70's??) were 240 only and had two hots and a ground
(red/black/green). The most modern code calls for 2 hots (red/black),
ground (green), and neutral (white) if NEEDED.

Your cable is suitable for the latest code which calls for a 4 conductor
receptacle and plug with 3 blades parallel to each other and a round or
'D' shaped pin for ground. I'd recommend heading off to Home Despot or
similar and getting a matched set.

I *think* it is still code legal to use the 2 blade and 'D' shaped pin
setup (maybe Bruce Bergman will weigh in here) which lacks a neutral.
And yo will still find a lot of older installations with the angle
blades which is not approved.

Hope that helps.

Thanks. It does...sort of. I am puzzled then with what I do with the
wires from the welder to the plug. If the plug has '3 blades parallel
to each other and a 'D' shaped pin for ground', how does that get
wired to the welder properly since the welder wires (on which there is
no plug) are only 2 hots and a ground?

Sorry for being a pain. I'm just trying to understand so I'm armed
with as much knowledge as possible before heading off to the store ...
again. I want to come back with the right stuff and be welding
tomorrow night.

How many conductors are in the welder's cord? Three or four?

Any help is appreciated.

Never mind. I think I've got it.
