Wondering if anyone has used the 4/0 welding supply wire.... I have some interest in using wire this thick just so that I'll only need to run 1 run instead of a few 1/0 runs.

I'd like to see some size comparison pictures or something.

Also wondering how the 1/0 welding supply wire compares to the knu wire as far as size.

I read some stuff on here about how copper is so much better than copper clad aluminum, and would like to change it up now.

Thanks!

Unless your pulling 1200 amps i wouldn't be too worried about 4/0.. Maybe 2/0

www.cableyard.com sells 1/0-4/0.

Are you having any issues with the copper clad cable or are you just wanting to change because some people think it's "better?"

I used a bunch of 4/0 a few years ago, Supraflex welding cable. It wasn't over 1" in diameter and was super flexible. I gave my last 40ft of it away to Marshal Joyner... lol...

I ended up using the heavy copper crimpable ends that are used for indsutrial apps, they worked bette in my opinion....

CCAW is straight up crap. Seriously, it is a joke to buy that stuff. You are paying for fancy looking aluminum garbage.... Of coarse it will work fine if you buy 1/0 to run a single amp that is a few thousand watts.... But it is a big ass waste of money. Seriously it is a joke played on stupid consumers...
