How To Protank and evod rebuilding

[sandwich_slayer]

Twisted wire will lower the resistance SURELY !!!!!!

Thats why twisted coils run sub-ohm !!! - Its like using thicker wire, which means the current flows easier through the wire (so LESS resistance) which means hotter!!

The way to stop the grommet getting fried would be to run no-res wire from the terminals (Centre post / grommet) to the start of the coil, but who wants to weld/twist no-res/res wire on something this small?

Apologies if I have got this wrong???

That sounds right to me, doubled wire would be half the resistance and get hot faster.

HEY all I Know is that on a video on nova rebuilding someone suggested it to stop the Burning and it worked.

Dont ask me about the science of it.

If it works then thats great. This has been a really useful thread to me too because it made me think about twisting the wire and I found some videos ont youtube where they rebuild coils using twisted wire.

Ok. I have been thinking about this and I THINK I have figured it out but correct me if I am wrong.

Thinking about wire thickness, the thinner the wire the higher the resistance right? The higher the resistance, the harder it is for electricity to flow? The harder it is for it to flow, the hotter the wire?

So twisted wires on the legs lowers the resistance (makes it close to very thick or very low res wire) so the electricity flows easier through the twisted parts of the wires until it meets the hire resistance of the coil, which then heats up?

So yes I was wrong when I said it doubles the resistance of the wire, it halves it BUT that is good because we want as little resistance as possible until the electricity reaches the coil?

Am I on the right track here?

Dam this is confusing to try to explain!

Think of a light bulb. The electricity will meet at the weakest point and heat up here.

No matter what the resistance of the wire is (assuming you are using the same piece of wire used in whole circuit) it is easier to heat up the single core than the twisted pair.

Path of least resistance!

When you are twisting the ends you are not creating the same effect as a double coil. Your are creating a joint pathway for current to flow at each end until it meets a bottleneck at coil.

Hope this helps.

So keep it short, twisting the wire for the legs is a good idea?

Based on what noisysprings said, it is a good idea. And if you have tried it and it works, it's a good idea.

Thank you for this! I was just thinking about trying to rewick a few of my Protank heads and this helps. Twisting the legs is a good idea too - I'll try it!

I'm a former electrician. Thick wire in sub ohm builds does get very hot, but that is due to the wattage / ampage.

Twisting the lega are a good idea, as it is the thinner length of wire that has the most resistance, and therefore heats the most.

If it was vice versa, the thick low res copper / brass connectors in our mods would get very hot, and they don't.

A thick 0,32 mm wire in a low ohm setup is still the "weak link" in the circuit, as the kanthal is a resistance wire and has more resistance than the copper and brass in the mod, and that's why the coil still glows.

Superb tutorial, thanks mate. Got my wire and wick just now, and got it right first go (even without the pin for wrapping the coil). I did 5-6 wraps though, so more like 1.5-1.8 (got no resistance checker).
