cotton wicks

[partywootdgr]

i just build my first rda coil 1.9 ohms on a igo l and it works great. thing is how often do you guys drip? because it seems every 3 hits it starts to give me a dry it/burnt taste, then i drip on the coild , to left and right of it and it goes away for about 3 hits. the rest of my cotton wick is saturated so idk whats wrong, did i use enough cotton for the wick? im clueless on what to do because the flavor and everything is awsome now i know why people say dripping is the best , but im going to run out of juice fast if im dripping every 3 hits and its kind of annoying lol . thanks again

1.9 is really high resistance and it will take a long time to heat up. And it's probably not heating enough to draw the juice to the coil. I usually wrap coils between 0.3 to 1.4 ohms depending on the device I'm using. Tonight I rebuilt my patriot at .3 ohms. I'm also using cotton which holds lots of juice. I can get 5 or 6 draws before redripping.

Possibly you have too much cotton? When you install the wick, it should slide easily through the coil. A little resistance but not too much. It swells when you juice it so if it's too tight to begin with, it won't wick into the coil very well. Less is more with cotton.

If this is your first build on an RBA, you're fine at 1.9 ohms. It'll heat up just fine. Ignore all the crap about .3 ohm coils for now. Study up on battery safety and ohms law before experimenting. Hats off to you for building a safe coil.

the juice will vaporize to the degree that you heat the coil… hotter burns faster, its just the way it goes… if you have a high nic % you wont need to vape as much, but if you like to vape more you lower your nic % and you go through lots of juice.

the cotton needs to be just right in the wick to get good flow… too much and it chokes your vape; too little and it won't hold the juice. Look at pictures of coils with cotton ie. in the micro coils threads.

1.9 is not very low (unless you are using a VV or VW and you raise the power to get the right amount of vapor) but its a pretty good resistance. Depends on what you are using (mechanical or VV VW).

Be sure to follow safety rules if you go lower than 1.4 Ohms… learn how to detect shorts and what batts to use.

*3 drops is about what we used to use for conventional disposable atomizers before RBA RDA's came along and you would get about 5 or 6 vapes before you had to drip…. the iGoL is for better flavor if you build the coil right and should take about twice as many drops… but its still a "dripper' meaning you will be dripping a lot.

Look into dripper tanks that hold more juice like the Kayfun, KF lite, or similar… great flavor and less feeding.

thanks , i watched alot of videos and researched alot about rda's. im using a vamo 2 i dont really want to do sub omhs , i think i put too much cotton to be honest now that you pointed it out . o and im running it at 10watts

I have 1.9 on my igo l also. Try using less cotton. Try also to leave a fluffy cotton tail sitting in the drip well. Make sure your coil is sitting level with the airhole. It may take a few tries but when you build one that works great it will be smooth sailing from then on. Also like the poster above mentioned 1.9 is more than fine. I get plumes of great tasting vapor using cotton on a 1.9 ohm coil with 4/5 wrap of 32g kanthal.

Also I drip about 10-12 drops and it lasts me a good while.

Good luck to you!

Here's my setup with my cotton tail wik

Thanks for the reply , ya im using a vamo2 im not really looking to get into sub omhs and mechanical mods right now . i bought the igo l for the flavor and ya its amazing . i built a micro coil for it, i did about 10 wraps with 30 gauge kanthal . o and im using aw imr 18650 2000mah unprotected batteries . im actually looking up dripper tanks right now lol any suggestions that wont cost 100$

10 watts sounds about right....also, if your airhole isn't right in front of the coil, it can taste a bit burnt, harsh and low vapor. I don't really do sub ohm. .8 ohm is about as low as I'll go but I prefer to be between 1.2 and 1.5. I tried dual coils, super low ohm, all that crap because I like tinkering. I don't like any of it. A good micro coil around 1.4 ohms with .28ga and cotton is perfect for me. Batteries don't die as fast and juice lasts a little while. Great flavor and vapor...but it's fun to experiment as long as you do it safely. Have fun!

Theres a lot of clones available for the kayfuns right now. I'm not sure which ones are good and which are bad...I have Kayfuns. But it's an awesome atty and really easy to build. Perfect for micro coils and cotton.

hey thanks again ill be sure to look for some clones then . i appreciate the info

Only RDA I have is the IGO-W. I wrap .6 to .7 single microcoils or .5 to .6 dual microcoils. I drop about 7 or 8 drops for every 10 hits in the single and 10 to 12 drops every 10 hits in the dual.

For what it's worth I prefer the single. Maybe I have to build a lower ohm dual cause with the dual I find it takes too long for the coils to heat up. My batteries I have are only rated to 10A though so until another day.

Hope that helps.

I think it is too much cotton...try less.. I rap 28ga on a 18ga blunt tip needle, 12 raps about 1.4-1.5 ohms and put a little pice of cotton UNDER the coil..it's about 1/2 the size of a dime. give it a try...

IGO -L on a Provari. Micro coil (1/16th inch drill bit), 32 gauge Kanthal, cotton. I generally make coils at 1.5 to 1.8 ohms, 3.8 to 4.0 volts. Pop the drip trip, eight drops, and vape away!

just curious im using 30gauge kanthal doing about 10 wraps getting around a 2.0omh should i try 32 gauge then? idk whats the ideal gauge wire for doing microcoils? im aiming for the 2.0 ohms i was just wondering would it be easier using 32 as opposed to 30?

 

[ukeman]

they are pretty darn close; the 30 is a tad thicker and imo better heating… but i do all sub ohms and use 28,27, 26 … someone who uses higher resistance could tell you the difference.
The point of a micro is tightly wrapped (touching) coil for good juice distribution and vaporization along the surface of the coil.
In that sense the 30 will take a wrap or two more to get to 2 Ohms than the 32, thus more distribution.

Hey, uke, long time no see.

One thing I'd like to add, is the narrower the coil, the more wraps you can get, too (i.e. a coil wrapped on a needle vs. a coil wrapped on a toothpick). The resistance of the wire is caused by the overall length and thickness of the wire, not by how many wraps are in the coil.

got ya , thanks again , so far ive built 3 coils all around 2.0 ,but like every 5 hits im still getting a dry hit from the cotton lol , maybe my coils now straight enough? ive used far less cotton then i did the first time around

Perhaps you are drawing too fast for the juice to get into the coil? Need some time between pulls for the juice to wick. Try taking a couple of pulls, then wait a minute or two to see if that helps..
