I don't see any issues with this.

I used 6 AWG because I got some for free and it gives me room for growth.
For a welder it should work fine because of the Duty Cycle consideration. For what it's worth my welder came from the factory with a 12 Gauge power cord.

Yes #10 is fine for the ground.
See table 250.122 for ground wire sizing.

In the owner's manual, the max breaker size and minimum wire size are typically listed together.

That's the figure in the 90° column.
Since the terminations are rated at 75° you need to use that column, which is 50A, so you're still golden

If you are piping the only machines need heavier than a 10 are some of the 252 class feeders.

What the heck is a 252 class feeder?
It is a 35 year old Hobart wire feed. It is a 3 phase machine and it sprays really well when you crank it up. If you want to run it on single phase you just drop the 208 lead and it works just right that way. You obviously can run less amps when wired that way. Pretty much done with the heavy work.

Yes, you probably need the number 8. Some of the 250 wire feeders are really powerful and will output 300A. Miller 251, 252, the new 255. They have 60%duty cycle at their rated output. They rarely get run that hard in home shops.

It would burn a factory gun up, need to use a different gas than the common one wire 1 gas shop does to warm up a number 10 with a wire feeder. I think they will spray 045. dr clyde and a couple others would be more familiar and current. I have a red Wirematic and it lists 10, got a SPT 130 which is the current 180, they listed 8/40 for it. I never understood how they came up with some of that, it was an early model, same thing later lists 14,,, ha I think it comes 12 cord.

My Hobart goes up to 375 Amps. But that is when wired for 3 phase. Not sure what it will do when you drop a leg and run it on 240 single phase. Guessing 250

I am not sure either. There are guys here way above my head, only thing I know is the simple part of wiring common machines. I live on rural power. If I was starting over today might look at some conversion equipment but I have coped and keep it simple and really don't need the power.
