Repetitively burning coils

[coilburner]

Sorry if this is the wrong section but it says I need to post here five times before I can access the other parts of the forum and I need an answer ASAP. I have an evod, the one with a single coil, and I keep burning out coils or getting duds (about 6 all together). All but the original coil that came with the tank gives me a burnt hit at anything above about 7 watts. The original coil would hit fine at anything below 13 or 14 watts. I have tried all different ways to prime the coils and nothing has worked. I tried leaving them submerged is juice for 10-15 min, tried leaving them in a full tank with it standing up for about the same time. I also tried coils from two different stores in case on did get a batch of duds. I have gone through about 14 coils on other tanks and never had this issue. What can I be doing wrong?

the original coil was probably 30 gauge and the new batch 32 gauge.

when you buy replacement coils you can bet on the ohms but you have no idea what gauge / power range they are going to be.

I haven't got any idea. I never heard of anything like that. But then, that's why I wind my own.

Take 10 sec breaks before taking a drag of the vape, this usually helps out.

It might not be you. I would make sure that you let em soak (you did) and that you keep it at lower watts. When i used my evods, I was barely above 7 watts most of the time. What device are you using? If you have a battery that doesn't step down your voltage, it might keep running at too high watts.

How many seconds is your draw, and how long do you let it rest between pulls? I like long drags and therefore could never crank it up very high when I used evods. Best of luck to you.

 

[djsvapour]

Not wishing to sound mad, but I was burning out evod coils at even 9 watts (back 2 years ago).
8 watts would even get mad at me too, sometimes!
You are expecting too much from an old and fairly low power system.

PS - I have close to 60 used coils in a bag in my vape box.
Either 1) vape at lower power or 2) rebuild the coils using kanthal and cotton wool or 3) get a more modern tank suitable for more power in the stock coils.
I know that the iStick 20w couldn't even step down enough to make using evods and protanks a guaranteed success. y.m.m.v.

toooo muuucchhhh pooooowweerrrrr
tone down the watts or upgrade the tank

 

[mcclintock]

If you can find the original coil look at it, Kangers have fine print on them, I'm curious. I usually vape at 6 watts or so (3.5-3.7 V) on these, very good actually but needs more patience. I'm wondering if you were just taking very short drags, which works better with a bit more power, but need more vapor and cross the line it's got to be done at a sustainable pace (drawing in juice through the wick during the hit, instead of using just the build-up).

 

[Baditude]

Are you using a high Vg juice ratio? Vg is thicker in consistancy and doesn't wick as well as Pg in the cheaper tanks, leading to dry hits.

Pre-soaking your coils is a good idea, but you might also need to do occassional "primer puffs" to keep the wick/coil wet as you vape. Take a draw as usual, but without any battery power. Also make sure you always take a gentler, longer draw than you might with a cigarette.

And keep the watts lower with that tank. If you want to vape at higher watts, upgrade to a better tank that can handle them.

Most clearomizers use silica string as the wick. It doesn't wick as fast as what cotton might. It also isn't as good of a flavor carrier as cotton or polyfill (cartomizers).

I use evods every day, on non-VV Evod batteries. Never had this problem and I vape high VG. But I don't turn up the voltage and I think 6-7 or so watts is best.

Even Single coil RDAs are very popular, you might get some ideas here

I have tried using 70% vg juices and also 70% pg juices, same results. I have also tried taking a longer slower draw and quicker harder draws, usually the slower draw resulted in more it being more burnt. It doesn't matter how long of a break I take between drags, it’s always the same. Btw I’m using the istick 30w so I don’t believe it has a true step down but uses pwm I believe.

 

[Racehorse]

Also wanted to say, with an EVOD clearo, I have several boxes of genuine Kangers, but i get them at 2.2ohms. Or even 2.5ohms. The 1.8ohms burns out VERY quickly and do not last very long IMHO

14-15 watts is way too much for a single coil EVOD clearomizer.

With an istick 30watt, you probably need to go to a dual coil clearomizer or one that works better with a higher wattages. I dont' have an istick30watt so I can't say, but I'm gonna guess the wattage is way to high for a single coil evod?

 

[coilburner]

While 14 or 15 watts is very high, for the single coil, I can’t even use 8 watts without it burning. And like I said the original coil that came with it worked flawlessly up to about 13 watts.
BTW, thank all of you for all the help and quick reply's.

 

[Robert Cromwell]

You can try drilling out 2 of the airholes to 1/16 inch. The increased airflow will allow you to vape a bit over 7-8 watts but not a lot over.
My 2 ohm single coil evods tend to get burned taste at 4.1 volts or higher. And they are drilled out.

The original coil that came with it obviously is not the same as the replacement coils;
by the way, you did not mention I don't think, what the ohms of the various coil are.

Different coils will work at different wattages; depends on :
- ohms
- thickness of wire (gauge)
- type of wire eg; kanthal , nichrome
- whether single or dual or other

34 gauge coils are going to burn out pretty fast;
I've got 28 and 30 gauge coils running for months;
so far the only 30 gauge coil that actually burnt out on me was when I dryburned it and quenched the hot wire with water.

I have drilled out one of the air holes, not sure what size.

I have tried 4 of the same ohm coils as the original, 1.8 ohms. I have also tried 1.5 ohm coils.
I have no clue what gauge wires they are. Does what you said about the different gauge wires hold true no matter what resistance it is?

a short thin wire of 2 ohms might run on 5 watts,
but
a long thick wire of 2 ohms might run at 100 watts.


the gauge of wire is a measure of how thin it is.

==== oh, and to answer the question: YES.

I have had an interesting problem .... I splurged on a huge bottle of milk man e juice... Freaking stuff is so sweet at 80-20 I was going through a coil every other day. Had to give the stuff to the trash man. I don't know if it was the vape ratio or what. My sub ohm setup was not happy.. Neither was I . Bought some 5050 five pawns stuff today.. Much better. Ahhhh
