Trident v2 clone dual coil build help!

[ibumbleborg]

Hi! i got my 1st mech 3 days ago and built a dual coil 5 wraps of 30g on each coil and read about 2.6 Ohm on my multimeter wich has a 0.9 ohm so its about 1.5-1.7 Ohm wich is a bit higher than i aimed but its my 1st build ever, im not having any shorts or warming issues just that it takes a little to long to warm up the coils and start producing a good amount of vapor and 1 of the coils seems a bit more burnt than the other one thats what i am concern about I am using a sony 18650 30a battery

Questions are:

How do i know if i have a short and thats what is burning 1 coil more than the other?
Should i aim for lower Ohms for a faster heating-vapor production coils? if so i only have 30g wire will this be achieved by less wraps or more wraps
i did a little test and blowed air into the trident (not inhaling) and 1 air hole throws very little vapor compared to the 2nd air hole.. what does this mean?



Tyvm i hope some one can answer my questions!

I'm unable to tell you, what your multimeter would show when you have a short.

Your coils must be slightly different, either due to different distance between the wraps, or different resistance of the coils themselves. Therefore, one coil heats up faster than the other. Try utilizing a micro coil to avoid that problem.

Regarding the Kanthal wire itself. In order to get lesser resistance of the wire(s), you can twist 2-3 pieces of wire together.

You'll see an example for twisting wires, when you take a look at the coil building tutorials at http://m.youtube.com/channel/UCgZd5ygXFoQry9KDGlddSBg

Hi ibumbleborg and welcome to ECF! You did very well with your first build. From your pictures I suspect the difference in your coils are due to one coil being smaller and tighter on the wick than the other.

Questions are:

How do i know if i have a short and that's what is burning 1 coil more than the other?

A short will show up as a zero, or close to zero reading on your resistance meter. If you get that, stop and figure out what is causing that and fix it before you continue. A short as you know is not good in vaping.

Should i aim for lower Ohms for a faster heating-vapor production coils? if so i only have 30g wire will this be achieved by less wraps or more wraps

Less wraps will give you less ohms. Less ohms will give you faster heat. But don't go too far or you will go past what your battery can safely supply in current. With your Sony 30A battery you can go as low as 0.3 ohms, but I don't recommend you go that low. Taking one wrap off each coil should take you to around 1.3 ohms and you can see how that vapes.

I did a little test and blowed air into the trident (not inhaling) and 1 air hole throws very little vapor compared to the 2nd air hole.. what does this mean?

It's hard t say for sure. My Trident blows about the same amount of vapor if I blow into it from each air hole. It may be that you have an extra coil on one side, or that your air holes are not the same size.

I wouldn't worry about it for now. Take it one step at a time and let us know how it goes

ty both for your answers! you were very helpful! i dont want to do twisted wire builds yet. i guess ill try harder to make the coils very similar next build!

do make sure the coils are not shorting due to contact with the center post too. it sometimes happens when you fiddle with the wick. what i did was to put a little piece of cotton better the center post and the coil to prevent short from happening.

some one on the reddit forums helped me out.. it seems that one of the coils wasnt making a connection.. i just tightened down one of the posts and the ohms went down to 1.7-1.8 wich is about 0.8-0.9 and the vapor production improved a lot
