I am tooling up a new/old stick welder, and I have a pile of used welding cables with various connector styles and types. None of the cable is marked at all, so I'll have to ID its gage by exposing copper and measuring diameter. But even if I do that, I can't find a table which maps cable diameter to gage size. Anyone?
Well, that's for sure *way* different than the McMaster Carr table. And that one was way different than the other tables people pointed out. Here they all are for your comparison:

None of these tables agree in the slightest. Sheesh.
Only one of the tables refers to the copper wire size INSIDE the cable. All of the others refer to 'nominal outside diameter' And the AWG table is not particularly accurate for highly stand , highly flexible cable. It will run around 10% to 15% larger in diameter to account for the air space in between the conductors.

ID the cable, Steve. I need to do that in order to buy fittings. I have one piece which was believed to be 4/0 but if it's 3/0 it would need different fittings, for example.
