anyone know of a table of welding cable diameters?

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?

You want an AWG wire size table. Here's one.

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.
For identification purposes, you want the copper wire size, don't really care about the insulation size.

Is your intent to identify the cable, or to choose one that is right for the welder/amperage and the length of cables you want to run?

I would trust the McMaster table and would not take AWG sizes for solid or low strand count wires.

The McMaster table only shows the external diameter of wires with specific brands/types of insulation. What good does that do when trying to figure out what amperage the cable will handle?

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.
