.2ohm coil - runs dry instantly

[Bobbert]

Hey, I've been doing rebuildables for a while but haven't ventured much into low-ohms until just lately. I recently double-braided some 28 gauge kanthal for a .4 ohm coil, and being VERY pleased with that, I took it to the next level and quad-braided. So I'm running at .2 ohms with a dual coil, and jebus the vapor production is incredible.

The problem I'm having is that I can only go a few seconds before the juice runs out. So it's hit, drip, hit, drip... I'm no pro but I've seen people do better. Any wicking or other tips for solving this?

I'm using a tobh atty with a copper nemesis, all copper pins... picture attached.

Thanks!

You need to be running a BED of cotton, not the feed wick

Not so sure I'd even think .2 is safe. Nothing to do with Battery load/max load but more to unexpected failure. Not a perfect world.

Simpler to understand. Would YOU run 200MPH door to door with another car with an unknown driver at the wheel?

i stuff my coils closer to the deck - as close as i can get. It lessens the TH too which may or may not be what you like. On An Atomic with silica 26g kanthal duals at 0.25Ω.

I have a tobh atty and a copper nemesis and I use 24 guage kanthal. I make a 4/5 micro coil and a half of an organic cotton ball for my wick. A half of a half roughly for each coil. That puts my ohms at .28. I usually get 2 to 3 hits before I have to drip again. It puts out very well and I don't have to vape it very often. I would say that maybe you should try putting a little extra wick to hold e juice.

 

[Bobbert]

Heh, I wouldn't even try it if I hadn't seen other people do it first. I'm reading a stable .22 and keeping a close eye on it all - it's not hard when you have to drip so often, after all. And, yeah, more cotton, I should've thought of it.

I do like my throat hit but with this much vapor it's more than I can handle. I'll keep that in mind when I replace this coil - IF I replace this coil!

At .2 ohms yeah it's going to dry fast. The only option is load up with cotton. That helps a tad. However, I'd never run that low. Too many things could happen.

Good luck

Honestly I've seen people do lots of things, but that doesn't mean I'd do it. Just saying. Honestly, there's just way too much that could happen when you get the low. Good luck either way.

agree 100%.. personally i really like flavor and really low ohm vaping pretty much makes everything taste metallic or void of flavor altogether.i get pretty much the same amount of vapor from a single strand of 26GA dual coil @.45-.5 OHM. and i can actually tastes it. with the milled juice wells in RDA's like the Jam, TOBH etc. i can get as many as 8 hits before dripping again. i just tuck my wick and put in an extra cloud while still allowing room for air flow under the coil. works for me... best of luck and stay safe everyone.

I have a quad 28g .23ohm setup in my TOBH, and I use an extremly small amount of cotton through the coils then tucked under,
I get about 5 hits per 8 drops.

using 22ga .23ohms in an igo-w5 with a center post build using rayon wick......
plenty of vapor ...getting plenty of hits....no problems...
using 30 amp lg battery. lots of wick gets you more hits.
as far as all the nervous nellies posting up.....
when i was 12, i was scared of girls.....good thing i learned about them and got confidence

When I was 22 I learned about electronics, physics, chemistry, and the error inherent in any measurement. Good thing I learned about them and how to be safe.

 

[brianc11111]

i know all about it too and im safe....my point was, it seems like alot of posters are just scared. no need to be scared if you are educated on the subject.
im sure kayfuns look pretty awesome if youre vaping on a aspire bdc.
the trick to beat the "error inherent" is to err on the safe side.

Confidence and wisdom are not the same.

Many a lion tamer have been confident they new what they were doing - right up to the point of getting mauled.
Many Wise men/women have avoided stepping inside the cage.

No nellie here. I often do things I would never recommend another try. My choice, my responsibility.

Hi

it looks like twisted wire not braided, goto the link in my SIG for braided


if i get problems with the wick being vaped off to quickly i either take shorter toots, make the inside diametar of the coils bigger, leave a little space between each wrap as you wrap your coil or all of the above

you could twist up 3 lengths instead of four, giving you more room to make the ID bigger or/& to leave gaps between each wrap.

nice build but me personally i dont like to much wire in my atty like that, the atty gets to hot or stays hot

 

[brianc11111]

yes it is your choice,and mine too....the original poster wanted advice on his build.
not childproof warnings

 

[sawtoothscream]

my friend and brother run around .2-.3. We all use peaches and creme yarn and just several hits before its time to redrip. IDK what you built your coil on, but if its 5/64+ just the yarn a try.

I understand. You have to build how you like. There's nothing wrong with trying new things, but at the end of the day people usually stay within their comfort zone.

It's obvious that high temps, lower resistance, and more air vaporize more juice. To keep up, you have to make larger coils that can handle larger, puffier wicks. It's why souped up engines need more gas and air.

I vote for more cotton and bigger coil diameter to expose more juice to atomization. Finding the right balance will fix the problem. You also have to make sure that the ends of the wick are soaked in juice to keep up with the flow.

 

[SingedVapor]

If you get crafty I'm sure you'll figure out something. I've never used that low an ohms before and don't really plan on it, as my comfort zone is between .6 - 1 ohm.

But... If you are having a problem with juice being wicked get a bottom feeder such as a reo. Then squonk as you vape so you constantly feed juice to the coil. Just in idea

 

[G-weezy]

Try the U wick method. It holds juice pretty good. I'm at .25 and I can take 10 pulls without dripping.
