I've just wired an external box with 10/3 solid copper 600v. wire with AWG
running about ten feet from the panel to an outside outlet. I need to run
it 100' to my slab where I weld. I want to use MAINLY a Lincoln SP 175+,
and the input amperage on that is 22 amps. Can I run a 100' of 10/3 AWG
with stranded wire safely? It's the big yellow one available at HD.

Now, I also have an AC 225 Tombstone that pulls 50-63 amps. How about that
one?

I'm probably going to get a gas driven welder/generator in the future, but
this is what I have to work with NOW.

Safely, yes. Voltage drop: resistance of 200 ft (round trip) of #10
copper is about 0.2 ohms, drop of 0.2 volt per amp or about 4.4 volts
at 22 amps -- shouldn't be an issue. It'd be 12 volts at 60 amps or
5.5% of 220V, shouldn't be an issue.
