Welding Wire Size

[Slobalt]

Before you say it's been covered, I know, I searched it. My question is most of the searches I've come across say to get 2/0 welding cable because it closest to 1/0 CA cable. But I've looked up what the diameter is of cables to awg standards and I used knu wire as a reference. To me it seems like 4/0 awg is closer to CA 1/0 or at lest knu's wire. Can anyone help shed some light on this subject to help me decide what size wire to get.

Use the AWG standard and pick the size of wire that handles the right amount of current and keeps your voltage drop low. WIRE

2/0 welding cable is ~ the same size as 1/0 car audio wire.

4/0 welding greatly dwarfs 1/0 ca wire.

if you're trying to get wire the same size as 1/0, then the 2/0 welding is what you want

Car audio wire is oversized. So 1/0 CA might be closer to 2/0 welding wire, but 1/0 welding wire is...well 1/0 wire.

Most ca wire is oversized like already said. 1/0 car audio is the same size as 2/0 welding wire. Ive had both.

If you wondering, I was looking at pure copper welding wire. Stiff stuff! I fit 3/0 wire in my DD m2b amp. it was some hilarious price, I think it was C$14 CAD a foot +Tax. So didn't buy any, they did give me that sample for free. I barely can get the screw to go down, It is hard wire.

Buy from electron beam. Best welding cable around and it's cheap too. $14 a foot is stupid prices, I can get 1000mcm for that price which is like 3" diameter.

Nice wire for a good price, I wonder how much they charge to ship USPS to Canada? I'd get 50' of 2/0 or 3/0.

I was looking around on the web awhile back & i think i came across Wire & Supply. But I forgot the site name. Thanks

Just started running the electron beam 2/0 in my car this weekend 6 runs total it's a little less flexible than CA wire but it's a lot heavier fits in all my stuff although it's a little tight going into my fuse holders.

You using lugs or those ring terminals? Im planning to buy 100' of wire, but was between royal cci and electron beam.

Using sky high 1/0 lugs for a few things, I used to use the crimp terminals but I like the heath shrunk lugs better.
