    New guy needs some advice on wire type....

    Hey folks. I just built a shop and I am about to wire in two outlets for my Christmas present(Hobart 210MVP). I am a hobby mechanic who uses air tools and would like to try some painting in the future. I have purchased a couple of 6/50 outlets, two 50amp breakers, and some 6/2 wire. My question is not about the wire size, but how many wires to run.
    I see that my 6/50 outlet requires two hots and a naked ground. It is my understanding that the 6/2 wire I purchased will do just fine. Here is where I need some help. I am wondering if I should run 6/3 wire and leave one capped off unused for future possible requirements. I do not know what types of equipment require 6/3, but it is certainly possible that I could upgrade welders or may buy other shop "stuff". Would it be wise to run the extra wire or just go with the 6/2. Would 6/2 work with most types of electrical demands such as a welder upgrade or a decent air compressor?
    Any help would be greatly appreciated.
    I am ready to run wire as soon as I get your feedback.

    If you run 6/3 you'll never need it.

    If you don't.....


    6/2 will work for welding machines and compressors.

    I know some people like to run the 6/3 for the "just in case" but I would prefer a sub-panel in the work area and then you can run your circuits as needed from it.

    6-2 is all you need unless you want a clothes dryer in the shop.

    Or a stove. I've had two stoves in my shop, once for a big Christmas party where the house oven was tied up and I roasted two whole prime ribs out in the shop. Just yesterday I cured the refractory in my new forge in a $10 Craigslist convection oven (glass stove top was broke). Put it out on the curb this morning with some other assorted scrap metal and it was all gone when I got home from work. I did cheat however and ran them both off 3 conductors. shhhh.

    6-2 will be all you need unless you are running an oven/stove (they can be used for heat treating but never use them for food if you used for heat treating)

    They can also be use for curing metal coatings such as cerakote. Probably wouldn't want to use for food after that either.

    I'm also of the opinion that 6-2 is just fine for your needs, especially since you already bought it. If you were starting from scratch, I would have suggested running some flexible metallic conduit and pulling in some #6 THHN stranded wire. That would have allowed you to add the neutral at a latter time if needed.
