kanger coil rebuild question

[Dusty32]

hey's all. I just got some 36g kanthal as well as 2mm-1mm ekowool. So I tested the ohms on each of the original coils and they both read 4.6 ohms each which would give a total of 9.2 ohms unless I am missing something. My question is this. To get 2.0 ohm dual coil wouldn't each coil have to be half the total ohms? for example, 1 and 1 for 2 ohms and .5 x 2 for 1 ohms? also, I have cotton balls that say they are 100% cotton. not sure if they are safe to use instead of eko and silicon.

Warning you need to do more homework. I promised someone so apologies for the soap box. You need to understand Ohms law and practice battery safety when you rebuild. The total resistance would be 9.2 only if they were in series. Almost nobody does that on repairables. They are in parallel so you use this formula. 1/R1 + 1/R2= 1/R total. Or if they are both the same resistance you divide by two and come up with a total resistance of 2.3 ohms with two coils at 4.6 ohms. One other thing you need to know you should if at all possible use NR-R-NR wire to rebuild them. NR = silver wire very low resistance and R = resistance wire. Otherwise you cook the rubber insulator on the bottom. If you look at the wire in the original head you will see a seam on both ends of the coil right after the wick. Sorry for the soap box but I made a promise.

I am aware of battery safety. I was aware of the ohms law in regards to V = I x R. I will look up more on ohms and try to see if I can find more info. I was advised to use 36g kanthol by the shop I went to. I am just confused on the duel coil ohms as to how you get 2 ohms from 2 4.6 ohm coils. If I understand correctly if I wanted 1.8 ohms I would need two 3.6 ohm coils.

You may know ohm's law, but you do not understand resistance well. The equation you used originally to calculate resistance, by adding them, only works if your coils are in series, like this --

If you want your coils in parallel, like this = as they should be in a kanger coil, you need to follow the equations given by steve above. If you are using two coils of equal resistance, you will get half that resistance.

You really should have had this figured out before you bought your supplies. There is a LOT more to vaping than ohm's law. While you're studying, look up watt's law and learn how to use it, because you will need that too. Don't forget to test your coils with an ohm meter! Good luck and vape safe.

I will add you can buy NR-R NR wires from fasttech for about 2.50 a hundred they work great

 

[dice57]

nope, two 4 ohm coils in parallel will get ya to 2 ohms, need to understand Ohm's Law, in series it additive, in // it's divisible. And 36 gauge, crap, that must be springy as all get out, would go with 30 or 32 to start of with. And Seriously, sure many changelbles can be rebuilt, but why? Smallest build platform and can get a decent rba for about the same price and do it right avoiding mass frustration. Just Saying.

Definitely need to go back and hit the books though, obviously you don't have enough skills on board to justify giving you advice, without worrying that you may get hurt or hurt others.

Everything you need to know, to become a competent builder/vaper is here at the ecf, go forth and learn, please.


Vape long and Prosper.!!!

Kanger protank 2 microcoil rebuild

good luck noob.

Just wrap a single 2 ohm coil for your Kanger head and save yourself a lot of hassle. I use 30ga. Also,use "organinic cotton" unless you want to boil it a number of times. Alot of folks are using rayon now too.

I wrapped quite a few coils for pro tanks and I've gotta agree with Dice57 that it's just not worth it... Fun if your into doing it just because you can but not at all worth it unless your ether really cheap (guilty here) or just like to experiment (also guilty) but in a world of decent $20 clones do yourself a favor and pick one up AFTER doing the necessary homework and AFTER getting a decent ohm reader to make sure your being safe, even a poor quality clone is going to blow that pro tank out of the water! But best advice I can give is put your internet to good use and study up, try to answer your own questions about these things. If your not willing to spend the time doing that then your not going to want to spend the time perfecting your builds so what's the point? Also it will prevent you from getting ripped into by people on the forum who may seem rude but are correct and not only have your safety in mind but the security of the whole industry. Be safe.. Have fun

There's no need to struggle and make your own coils for Kanger clearos. Just remove silica wicks from the heads, clean the stock coils and re-wick with cotton or rayon. They will last a month or two. The only thing is that cotton/rayon should be changed every 2-3 days. No big deal for me.

I agree that a rebuildable makes more sense than fiddling with used Protank heads. Rebuilding a Protank head is OK, but you still get the weak flavor with limited wicking ability. Kayfun is popular nowadays and it's easy to rebuild and maintain. It's a solid, stainless steel rebuildable atomizer that will last you practically forever.

Or, Rip's Protank 2/Protank 3 coil rebuild comparison. There's really not enough room in either Protank head for a good dual coil, although they but them together and make it work.

thanks for info. I was trying to find info on the net regarding my questions on the subject and have been watching vids and such but have not been successful in finding such. Almost all vids i have found use one coil. The ones that use duel coils all use cotton instead of eko or silicon. Reason i wanted to rebuild kanger tank was just for experimentation. I will get a RBA when i really want to start rebuilding. I do have an ohms meter and test the coils as that is how i came up with the previously mentioned numbers. I was confused as to how it can read 4.6 on each coil although it states it is 2.0 ohm atomizer. It should be 2.3 if how i understand it is correct. I can find nothing regarding resistance specifically. I already understand that if each coil has diff resistances the equation previously mentioned is used. I am just trying to find info on how two coils of same resistance gets divided in half.

 

[Dusty32]

its cool i finally found a site that explains it. RTotal=(R1 + R2) / 4. I understand it now.

 

[DaveP]

Silica is less desirable than cotton because it's hard to draw silica through a coil and have it make good contact with the coil. Cotton can compress and expand to fill the coil and can be twisted on one end to get something through the coil that you can grab with tweezers to pulls the rest.

Most people who use silica wind the coil around the silica rope and then insert it into the head. That means recoiling unless you dry burn to clean. Both cotton and silica have their own pluses. With cotton you can pull it and dry burn, then replace the cotton and have a new wick.



With two parallel coils you can add the two and divide the total by 4 or just half one of them if they are the same . Two 4.6 ohm coils in parallel WILL read 2.3 ohms. The accepted formula for two parallel resistances is Rtotal= (R1× R2) / (R1 + R2).

That formula can be extended by multiplying all together and dividing by all added together. It's called the product over sum method.
