What size of Kanthal wire to get?

    Looking at Kanthal A-1 Heater Coil Wire to get some Kanthal wire for my Z-Atty-Pro, and AGA T2, but I don't know what size to get. I want my ohms to be around 2.5 to 3.0, wrapped about 4 - 5 times. What size should I get?

    Found this:


    Kanthal A1 Wire resistance Chart

    Kanthal A1 resistance wire is for making your own atomizers. Here is some info on estimating the ohms per inch on the different types of wire.

    This chart is for A1 type of Kanthal wire per inch, other grades are different.

    30 awg (Ω/in) 0.7 ohms
    31 awg (Ω/in) 0.9 ohms
    32 awg (Ω/in) 1.2 ohms
    33 awg (Ω/in) 1.4 ohms
    34 awg (Ω/in) 1.8 ohms
    35 awg (Ω/in) 2.3 ohms
    36 awg (Ω/in) 2.9 ohms


    The lower the ohms per inch, the more wraps you will need, this can be a trade off as the thinner wire needs less wraps but also has less surface contact to the liquid. Optimal seems to be 32 for most people.

    I wouldn't go any smaller than 32, but depending on your wick size, you may need a 5/6 wrap. I use 30ga on most of my gennys and wrap a 4/5 or 5/6 coil to end up @ ~1.6Ω.

    I'm still a noob with the RBA's. I'm trying 30 and 32 guage kanthal and have had decent success with both. Amazed at what just one wrap will do.

    For your target Ω I would recommend 32g but you may need more than 5 wraps depending on wick thickness.
    I wouldn't use anything thinner than 32g (33g and up) as it can be too fragile.

    32 on 500 mesh...works great for me.

    On a mechanical i'll use 28 for .6-.8

    30g if it's set up for the Provari and 28g if it's set up for the mech

    You'll need no larger than 32g wire to get that kind of resistance and probably more wraps because the wick hole is so tiny on the ZAP, but I find that I have better results with lower resistance and 30g on mine.

    I've found that the 32g goes "out of whack" a lot easier than the 30g. I'm doing a 4/5 wrap on my ZAP and my AGA-T2 with 30g and getting a 1.5 ohm coil which is working wonderfully at between 3.7 to 4.2v depending on my juice flavor. :)

    I'm curious, why do you want close to 3Ωs? Do you prefer a cool low watt vape or are you using it on high voltage?

    Primarily because Provape recommends higher resistance ohms on their devices. I've noticed the lower the resistance, the faster my battery drains also. I get good battery life between 2.5 and 3.0. I'm new to this, so i'm still learning.

    It seems the ohms+2 rule does not seem to apply to Genesus atomizers. People run them on much higher voltage.

    Wow I learned something new again. I've always tried to run the lower resistance ( between 1.8 and 2.0 ohms, so I didn't have to crank up my voltage). 2 ohm at 3.9 or 4 volts keeps TNT happy.

    Initially, when I started over a week ago with the AGA T2, I was shooting for higher resistance. Since then, I have made quite a few coil assemblies on 2 AGAs.

    Yesterday, I finally realized that I preferred the lower resistance coils. Currently, I have 2 AGAs set up at 1.3 ohms.

    Run the gamut with your coils and experiment . . . Enjoy the ride.

    Yup, that's been my experience.

    When I started RBA's, I wish I'd bought samples of 28, 30 and 32. I started at 32 trying to get 2-2.5 ohm coils, they didn't work the same as an atty or carto. Moved down to 30g @ 1.5ohm which was better, and now down to 28g @ <1ohm. Now I have 100 feet of 32 gauge sitting here, guess I'll get creative and make art with it, or something.

    The high res coils seem to simmer the juice, creating a pile of gunk faster and requiring dry burns daily. The hotter coils cut right through it, and now that I don't need to take 3 second drags, I get more battery life.

    Try them all until you find your perfect spot. For me and both AGA's I am running 30g @1.2-1.3 ohms and 4.3 volts and vapor and flavor are fantastic!

    I've used 28, 29, 30 & 32. For me, the 29g performs & taste the best. 4/5 go's from 1.4-1.6 on a AC9.
