Default New welder outlet wiring

My shop was wired years ago for 220 but no outlet was installed. I have black, red, white and green wires in box. The outlet called for by Miller is NEMA type 6-50 that has 3 connections with 1 marked ground. Do I just put a wire nut on the white wire and call it done? Thanks for any help.

You need to know what these wires are or what they are connected to in the panel. White is usually neutral (not used in 230 volt applications) green is always ground and the other two should be the 230, but it's good to check first.

What size are these wires? A welder pulls a lot of amps and I'm thinking #8 or larger.

You won't need the white wire as you stated. But it may not be that simple.
What size are the wires? They should be #6 for a 50 amp line.

It should be as JoeD noted but, as Speedbump noted, it would be wise to verify these wires instead of taking them at face value (you just never know what someone else was thinking).

Wire from box to outlet is 10 gauge. I have received dif ideas on the white wire vs the ground wire to the third prong. Will not change end from welder as it is new with warranty.

The wires are too small. You can only put a 30 amp breaker on that cable.

The plug is called for by Miller but the mig uses less than 30 amps.

Change the plug to a 30 amp plug.
The problem comes when the next owner says I can plug the kiln in there it's 50 amps and when that dosn't work he changes the breaker and burns down the house.
