Help needed. Cotton burns too fast

[Teoahpek]

hi all, would need some help or advice.
Currently using smok tfv4 tank dual coil.
My build is 24guage, 10coils. Cotton burnt in like 1-2hours of vaping.
I'm firing at 25watts.
Any advice is appreciated

Most likely cause is you are applying too much power before your wicks resaturate. You probably know you can't just hit and hit and hit and hit the thing with reckless abandon. The wicks will not keep up and the juice does not move fast enough and your wicks will fry. The viscosity of your juice plays a factor as well. You also have to be mindful how long your firing the mod. 24g 10 wraps in duals will take some time to ramp up but once fully ramped up will eat your juice and fry your cotton. Another factor is how tight your wicks are pulled in your coils. I like a tighter wick. Looser wicks will burn juice faster. It gives a great loose juicey vape but there are consequences. I hope some of this helps. One more thing. Many burn their wicks out before they even start to vape on them by not presaturating the coils and starting out slowly. It's a good idea to saturate the wicks and coils before you put the atty together then start at 10 watts with quick pulses to break the coil in slowly. Move to 15 watts and do the same thing....then to 20 watts. You will notice the vapor production starting to improve. When you feel everything is firing on all cylinders you can ramp up to your 35 watts. If you just slam your new wicks and coils with 35 watts from the getgo, you will burn your wicks before you start and miss all the real flavor.....let us know what you think.

whats the OHMs? or coil ID, i'll figure out the ohms.

Could try larger id on the coils and fewer wraps, try a spaced coil, use more or less wick, use different wicking material, SLOW DOWN.

coils are huge, watts are low. It probably takes a very long time to fire and takes forever to cool down once you fire it long enough to vape. Make some coils about half that many wraps. Start with 6. And don't use so much cotton. You need some space for air, especially under the coils. Glad to help. Enjoy the vaping!

This. I find 7-8 wraps ideal.

It's at 0.3ohm. Using 2.4 diameter.
I've tried different wrap but prefer this build due to the flavor and amount of vapor produced.
Different wicking methods have been tried but cotton still burns out too fast

I'd go to a 3mm core and fewer wraps, same OHM and same wire. Maybe even a little space between the coils. Flavor should be same if not better and won't cook the juice out of the coil as fast. Thus burning the cotton.

Well, loose juicy is my delight,
She come a runnin and we vape all night...
I couldn't resist, I get bored WAY too ez! Lol

Maybe it's just me, but that amount of contact area in a coil is going to require more juice than can flow through the wick. Once you've vapourised what's in it, there's no chance for the wick to keep saturated.

In my experience six to eight is the limit for continuous saturation. Importantly, the relationship between length and ID of the coil shouldn't get far beyond 2:1.

For example; a 28ga coil, 8 wraps @ 2.5mm. Spaced out 1:1 that's about 4.5-5mm long. With the right wick this can operate continuously. Ten or twelve wraps and the centre of the coil dries out. You wouldn't notice at first, but after a couple of days it will just stop performing well.

Every time you scale up the wire gauge the calculations need to be readdressed. Thicker gauge wire will also have a much greater differential of temperature from inside (touching the wick) to outside, making the relationship even less direct.

The suggestion that fewer wraps at a higher ID will help is the best advice at this stage.
