Wiring for 225 amp Welder

[sideways]

At my electricians suggestion, I ran 8/3 wire to hook up my 220V Lincoln Arc welder. I bought a surface mount receptable for it and was getting ready to hook it up and noticed there are only 3 connections on it and one of them is a ground. My wiring is red, white, black and ground. Can one of you electrician types tell me how to connect to this receptacle - obviously, I'm less than a novice...

Don't use the white wire in your 8/3, tape the end of it or throw a wirenut on it. You want blk/red/bare to your recep.

the white( neutral) is not required in this application because you only need 240v, not 240 and 120. Put a wire nut on it and tuck it back into the box.

The ground connection is probably marked green and should be the semi-circular shaped hole in the plug, while the two hots are the slots, and are interchangable red or green.

Probably a good idea to get your electrician friend back to guide you through the hookup to the panel. Electricity isnt very forgiving.

Thanks for the quick response..I was thinking I might have to ignore one of the wires. I'll wirenut it and tuck back in as recommended...great site!

and turn the power off in the panel before you go in. Always better to be safe then sorry.

Pretty sure you meant the hots are interchangable red or black. Green or bare is ground.

I hooked up my Lincoln 225 welder using 6/3 and put a wirenut on the white inside the receptacle box but I did land the other end on the neutral bar in the panel since I don't like loose ends.

Typo above. Last line should be red or BLACK.

Green is ground as stated in the first line.
