Hey guys how much kanthal wire am I supposed to use on my cobra rba? Does length of wire dictate the ohms?
How much kanthal wire do I wanna use?

yes, it does. look at the top sticky of the rba sub-forum for the values.
how much depends on the type of wire and the resistance you aim to have. most of the time I use 3/4 wraps of kanthal 32 on a 2-to-2.4 mm wick, this gives me some 1.5 to 1.7 ohm coil.

lenght of wire does dictate ohms. the longer the wire the higher the resistance. well if you ask me i am going to say 6 wraps of 28g, but i do not know what device your using, or how big your wick is going to be. wow you are like me when i used to study for an exam, i would study an hour before my tests, so i wouldnt forget any of the questions
it seems he's stating out.
using 28g with 6 wrap seems a bit complicated for a beginner vapdivrr, higher potential for more hotspots and what not.
I know that's what you use and there is nothing wrong at all with it, but 1Jocko may want to start getting his feet wet with something simpler imo

maybe its just me, but when i switched to a thicker wire, i had a way easier time with my builds. i just dont connect a lower gauge wire with having to be more experienced. honestly if i thought that 28g equates to being more experienced, i would not recommend it to someone that just purchased his first genny. why would this be un true? what is the difference between a 28g, 1.5 ohm set-up, compares to a 32g , 2 ohm set-up, i know it is not hot spots, for 28g is far easier to achieve a non hot spot coil. i would be truely sorry if i am wrong, and i am missing something that i should know, and i am not just saying that, i really mean it. this has become my second home, and i really look forward to helping out people here as much as i can, and love seeing al of these familiar faces also trying to help.
vap, I dont know, it may be me who is getting it wrong, but I have tried 28 gauge before and my experience hasn't been that great.
the thicker wire is harder to work with, Petar-K has a post somewhere here on ECF where he says that the most important part is not the wire itself or number of wraps, but that each wrap is as evenly spaced as possible (that's why his method works so well). When I used the 28 and wrapped around the SS mesh instead of a drill bit I found it was harder to have each wrap 'remember' the place I wanted it to stay (and yeah, I preheated my wire)
It's just my experience. And when I go for a higher gauge i seldom make it work (every time i use 36 it just breaks whenever I have a hotspot)
Again, most likely it's something I'm doing wrong with my 28. Maybe I'll grab some 30 gauge and have it both ways?

you know there is so much that goes on with these devices, being that i do not use the pete k method, and dont know much about it, i really dont know how my configuration would work with this method, and when giving advice for people that might want to try it this way, the advice i would give could be totally the harder way, i wish i knew evrything about all of it, so my advice would be always correct. but thats hard to do, so many variables that come into play. i just hope that most people before making a decision takes everyones advice together as one, and not just one persons advice alone. and thats funny about the wire wanting to remember its position, for thats what i thought was a plus with the 28g compared to a thinner wire. i always felt that a thinner more flimsy wire wanted to move around alot more then a thicker more sturdy wire. so like isaid before, i think it is important that people looking for advice takes in the big picture, then evaluates it all, then makes a decision based on a whole instead of just one's opinion.
indeed, best to grab a couple feet of each 28, 30, 32, 34 & 36, 3 feet of each is $1 @ Steammonkey
I've tested them all but 30 and just committed to a 100' 32 roll I bought on ebay (like 16 bucks shipped)

sorry for the vague description. most people use 32g wire, followed by 30 then 28g. the higher the number the thinner the wire. i always felt like a thicker wire gives better flavor, so i am partial to thicker wire, like the 28g. so one can start by choosing the wire first, then with that wire find a resistance that you want to start out with. most of the vv,vw devices out there go up to 6 volts. if you want to explore higher voltages, then you need to have higher resistances or ohms, if you want higher ohms you need thinner wire for the most part. 5 wraps of 32g will give you a higher resistance, then 5 wraps of 30g, 5 wraps of 30g will give you a higher resistance then 5 wraps of 28g. now most decide on the amount of resistance they want first, then use the according wire. so if your after a 2 ohm coil then 32g probably is the best choice. see with a thicker wire, which gives you lower ohms, you cannot use most of the 6 volts on your mod. lets say you did use 28g, and wrapped it 6 times,which depending on the thickness of your wick you might only get a resistance of 1.5 ohms, with 1.5 ohms you can really only push it to about 4.5volts, anything over this will test your device. but with a higher resistant coil you can go higher with the voltage. but sometimes higher is not better, and thats how i feel. i personally go the other way,i like thicker wire giving lower ohms at lower volts, i rarely go past 3.7 volts, so maybe you would say that i am not getting the most out of my mod, being it can go up to 6 volts. but imo higher voltages doent always equal more vapor. lower resistant coils can produce just as much vapor then higher resistant coils because they produce more amps and the vapor to me has a better flavor. you would think that a higher resistant coil, being it is pushing more volts drains the batterys faster, it is the other way around, a lower resistant coil will drain the batterys faster, because it uses more amps. but these are things you will have to experiment once you start. so to answer your question, it really depends. sometimes wire will come with certain genesis atomizers as part of the package, this is usually 32g, so i think it has become a starting point for wires, some think a thicker wire is more advanced, and harder to work with, i think it is the other way, but that is just an opinion. maybe buy a few different types and experiment. so all in all i think the first thing you need to do is start with a resistance in mind, then choose a wire to make that resistance. one more thing it is not the amount of wraps that decides the resistance, its the lenght of wire. lets say you have 2 exact atomizers, but one had a bigger wick diameter then the other and both had 5 wraps of the same wire, they would have different resistances, the one with the fatter wick would have a higher resistance, because it would be a longer piece of wire. good luck

paragraphs are your friend....
in my cobras i use 32kanthal with a 5/4 wrap for right around 2 ohms.
