Help- cotton keeps burning

[aceofspades991]

Hi all,

I'm looking for some advice because I'm getting frustrated with burning cotton wicks.

My current set up is an hcigar Stingray and an ehpro trident. I've got it set up with 2 micro coils made with 8 wraps of 28 gauge kanthal. I have tried using less cotton, using more, using a single coil ( not a micro) but I can never get more than a day out of my wicks and more recently, I'm only able to go for a few hours. Below is a pic of my current set up. Is there something inherent about the atty and mod that make it such that I can't use cotton or am I doing something wrong?

Sorry mate, can't see the pic... I figure by your description that your wick is just not getting enough juice to your coils. Have you tried different wicking material? How have you prepared your cotton? What's the resistance on your coils?

 

[Chris405]

Are you testing your coils before you wick them? Like when you fire your mod your seeing the glow from the coils start in the center and works it way out? What are your current ohms? How often are you juicing your wicks? When i put cotton in mine i put as much as i can get through the coils.

 

[aceofspades991]

Sorry, here's the pictures, and its measuring out at 1 ohm.

 

[aceofspades991]

Yes, I do test the coils before i wick them, the burn evenly. I've been adding juice every 3-4 hits, sometimes more often.

Not enough wick. Here's how I wicked with cotton tonight on my modified TOBH running .59Ω duals...

I drip 5 drips every 4-5 hits.

a suggestion is to wrap your coils close together, like touching close. I think seriously thats the first coil build i have seen like that in a rda.

here is an example of what i do.

thats in a genny but turn it sideways and you will get it

i couldnt get this image to rotate....

Gosh, pretty impressive coils.............I need to go back to watching YouTube's.

Ace, your coils don't look at tight as the othe pic above. You making them and pinch and heat the coils before and after installing them.

Gator's look nice and like he said you need a little more cotton.

 

[aceofspades991]

thanks for the suggestions. I'll give that a try.

Definitely need to wrap your coils tighter, you can tell by looking at them that they aren't heating evenly. This is a single coil 5 wrap micro with 22 kanthal. I've been vaping this all day and the cotton is still white. You want the cotton to slide through pretty easy, too much and you'll choke it and get dry hits and zap your cotton.

 

[Despraci]

Yeah... coils need to be pinched together. Are they also wicked through both ends so both have tails touching the deck? Remember liquid needs to wick from both sides to properly feed juice to both sides of the coils.

Jax's coils are pretty much textbook perfect, Chris's are pretty nice as well. I only have pictures of my Kayfun builds... but I'll throw one up to show another example of properly spaced Micro coils.

I would definitely recommend adding more cotton to your coils. Your juice is probably gone in the first couple puffs, and then it will dry burn your cotton which leads to that nasty flavor.

How do you like your Vulcan? Been thinking about picking one up. Can't beat the price!

I agree. See how your coils look kind of black where there is little to no wick on one end? There's your burnt taste right there.

one other thing you may want to consider doing is wrapping your coils on a larger dia shaft, try the 2.5 mm mini screwdriver as a wrapping tool.... the more watts up pump into a coil the more wick is needed and to do that, you need a bigger dia coil...

I'm loving it. It vapes nicely. It could use a tad more airflow, but it's working well for me (not really a cloud chaser). The flavor is fantastic, and the build quality is quite good. Stays nice and cool, and the well is so deep I haven't had anything leak out yet. I thinks it's underpriced to be honest. Grab one.

All adding more cotton does is allow for more juice to be held. Make sure you're not wicking too tight. If you're basically forcing it in there the juice will not flow from the outer wick to the coil and your coils will get starved. When there's not enough juice being supplied to the coil you'll get a burnt taste. At 1.0 Ohms you should have no trouble with burning wick if you have wicked properly.

What did you use to wrap your coils on? 5/64 drill bit?

 

[snipeslayer]

Good cotton wicking and closer coils are the best suggestions that I have for you. Also expand the coils diameter a slight bit - that will be more forgiving by raising the ohms and increasing the space for the cotton.

 

[Added]

Try to make sure both strips of cotton are as even as possible. Also, make sure it's not too loose inside the coil. Loose is good, but too little is also not so good. Finally make sure both legs are sitting on the deck nicely. The heat will suck in the juice so make sure there is enough material touching the juice to supply it. You don't have to go bigger if not wanted. This is 24g wrapped around a 1.2 mm dowel.




This one is spaced, but done evenly, this works well too.


Edit: Forgot to add for those curious, the top atty reads at .25 and the bottom spaced parallel reads .4
