Welding Wire vs. Anything else

[helotaxi 5,000+ posts]

car audio wires have a much higher stand count but dc current runs on the outer most diameter so the more stands the more flow you get that would be the most advantage to use car audio wire

What you are referring to is "skin effect" and is an AC phenomena, not DC. For DC transmission cross-sectional area is all that matters. Copper buss bars are actually the best though far from the most practical solution of DC power transmission.

why on that site is the "power cable" almost $15 more than the "battery wire" for the same gauge/length? //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Agreed.

holy crap!!

Helotaxi is back!!

Yep, the blue is actually darker than the photo, and the roll that showed up was Tsunami wire (Metra brand).

Because Red is more popular than blue.

theres really no quality difference at all?

 

[Ayrton 10+ year member]

No, I have both rolls and they are both Metra brands

When you get that roll in, compare it to the size of Kolossus Kable you have, let me know what gauge they really sold you. Sadly copper is not getting cheaper, its actually at a record high - in some cities scrap is at like $1.80/lb and empty houses are being gutted of copper piping by theives....even power lines have been stolen from a town!!

If it's that raptor wire by metra, which it more than likely is at that price.It's actually pretty decent wire.It's pretty flexible.

I bought 4 gauge from welding supply and it's the most flexible ive used. Black welding cable plus tech flex (your color choice) and you have some great looking cable.

I ordered two rolls, and they sent me one roll Raptor and one roll Tsunami.

Its not true AWG

Its not true AWG

If it's 2X as cheap you can do double runs and come out on top. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

the 2/0 gauge wire i got from http://www.weldingsupply.com is extremely flexible and i used my ddm to read the resistance across a 30 ft length of it and it read 0.3. i also read the resistance of a 10 ft piece of raptor 1/0 ga. wire and the resistance read 0.8 so in this regard i determine that my welding wire is just as suited if not 0.5 ohms MORE suited to use then the "car audio" wire.
