Which 220V Plug Type do most welders use?

Just as the question says, which 220V plug do most welders use? Or if they're different, which one does Miller use? Here's a spec sheet for the MM175 but I'm not sure what I'm looking for. I've been searching and reading up on wiring, and talking to a couple friends of mine who are/were electricians all week long to learn this stuff. I'm going to wire my garage very soon and want to put in a receptacle that will match any future welder I get. I don't even have a 220V welder right now or I would just match it up. TIA.

Edit: To the mods, move this if necessary. It is technical and relavent to Jeeps because the welder is for the Jeep, that's why I put it here.

240 volt, 50 amp NEMA 6-50R.

Thank you.

I think I'm a bit skeptical about a 50 amp plug on a MM175 with a max input current of 20 amps. I've got a 50 amp plug on my stick welder and I'd be pretty surprised to see that on the MM175.

Never seen any reputable manufacter yet that didnt use the NEMA 6-50R configuration(25 yrs IBEW)!

My Lincoln Pro 175 came with that plug. For 7 bucks I put a 4 prong Twist Lock plug on it so I can use it on the generator and in the shop.
