Burnt harsh taste. Need he'll with dual coil building.

[codyb88]

Hi guys, I'm new to rebuilding, I built a dual coil yesterday and it's around .3 ohms I believe, maybe more. I'm getting a really burnt taste using a tobh atty rda with all air holes open sony vtc5 batteries, stainless nemesis and give pawns grandmaster.

I would even build quad coils if that'll help with burnt taste and just awful taste in general.

Could be a hot spot? Did you pulse fire the coils and make sure they were all burning equally before you wicked it up?

Vague on specifics, and too blurry a photo to get a wire type and gauge or wrap count... better data or image would aid in providing more useful diagnostics, and to replicate a resistance model.

What I can see in the image... offers no indication of burning wick, yet. Burnt wick hiding inside the coil is it? ;-)

With nothing else of value to go on... I'd have to lean towards jim's guess, or not enough air... but either are just a WAG.

For starters, you don't know your coil resistance.

I would guess its a hot spot as well. Pull the wick our and make sure the coils are firing evenly from the inside out.

What level juice are you using? High nic will be harsh with that set up.

Second:

With buildng dual coils, and ESPECIALLY with lower ohms, it is harder to match the two coils. Chances are one coil is going to be hotter than the other because it has a lower resistance.

If one coil is 0.65 ohm and the other coil is 0.55 ohm, (effective resistance = 0.3 ohm)
with a 4 volt battery
one coil burns 24 watts
the other coil burns 29 watts

I'm sorry I tried taking a better picture but it kept getting too blurry.

I have 4 wraps with 2 pieces of kanthal each side. I think it's called parallels or twisted wraps? 28g kanthal. I forget exactly the ohms but it was .28 ohms to the best of my knowledge. The first few draws were great but terrible after the 5th or so.

The middle of them seemed to heat up faster than the outside of the coils.

How would I go about preventing burning wick?

I wouldn't advise anything other than buying a MM or at least an ohms tester to determine the true resistance or whether in fact you have built a short even. You are new to coil building and you are already vaping well into the sub-ohm range with no education whatsoever. You are a disaster waiting to happen.

You're trying to run before you can walk. Stop trying to build parallels and get micros down first.

I'm one of the most liberal here in regards to safety, but what you're trying to build is just stupid. Work your way up to advanced coils.

2 pieces of kanthal on each side would be like quad coils, wouldn't it? New to rebuilding myself, and as I only have regulated devices I haven't delved into sub ohms, or dual and quad coils yet. I seem to remember the guy at my brick and mortar mentioning to me that running parallel pieces of kanthal would be like running a dual coil though, and would be a way to do it when the deck isn't really big enough to handle a dual. He could have been wrong, but if he's right and you don't have a meter, you could be lower then you thought....

Dual parallels are quads.

OP, you're also running the risk of melting your insulators and ruining that Tobh. Parallels run super hot.

Dude... get an ohm meter, watch a lot of vids and read up first. Why on earth would you jump into those kinda builds off the bat.

 

[codyb88]

I HAVE AN OHM METER. Lol. I understand that I've done TONS of research I'm just not understanding why I'm getting burnt flavor.

You don't know why you're getting burnt hits because you don't know what you're doing. Research is great, but you need more real world experience. You've already answered your own question, but don't even realize it.

Cody, get a decent camera. Although people are criticizing you, no one can actually see your build..
