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.

For temporary work it should fly. You can normally push a
free-air cord pretty hard amperage wise. Heat is your enemy.
I wouldn't try cranking up the Tombstone very high though.
Mid-range stuff should be okay on it. Make sure the plugs
aren't dull/corroded over and that they have a snug feel
when you plug them in. Check/keep an eye on the plugs and
make sure they don't over heat. The plugs are the most
likely problem area.

Please log in for more thread options What Leon said about warming up the plugs.
Your #10 circuit should be good for and have a breaker for 30 amps. That
is plenty of amperage for the 175, it should be enough to run the
Tombstone at 120 amps with 1/8" rod.
#10 wire is 1.018 ohms per 1000 or .2 ohms for your max load. That works
out to a 6 volt drop on 240 volts, not a problem for most welders
(motors with a big input surge do NOT like this!) . Your main problem
will be the plugs and jacks, they will want to have resistance and will
heat up nicely. Try welding for say 30 minutes, check to see if any
plugs got hot. Fix any that do.

Please log in for more thread options Roy - solid #10 or Stranded #10 or Micro Strand #10 ?
Most tables are for solid wire. Resistance drops and flexibility raises
in the various types of stranded.
One could even be rich and buy two long welding cables add a ground safety
and put that into a cover - spiral or multiple long lengths of melt.
Always options. Could buy two transformers - kick up the voltage to 575
and then the next down to 240. The wires between have to have voltage
isolation but the current would drop in ratio.
Now the transformers must be large enough and they are the size of
a welder transformer or larger.
You might be able to find two industrial sized ones that are scrapped
or just left as they are large.
Gunner likely throws rocks at them cleaning out or building a shop.

Please log in for more thread options The wire tables say for 220 volts: 25 amps will drop 2% voltage over 100 ft.
with #8 wire.
60 amps will drop 2%
voltage over 100 ft.
with #4 wire.

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.
