I'm new, I need some help please.

Hi, I'm currently using a kangertech subtank mini. I have a few issues with my coils.
I prefer a warmer and thicker hit when i vape, I heard from my friends the best ohms to vape at is 0.5 ohms and I can't go above 4.2 volts if not i will get a dry hit.
Now I'm using a 28 gauge kanthal wire for my rba and I do about 4 coils. My ohms rating are between 0.8 to 1 ohms. I was wondering if i should change the wire to a lower gauge either 26 or 24 to lower the ohms.
Please help, what should i do? I would like to vape at 20-30 watts.

Yea get a smaller gauge wire... 5-6 wrap 24 ga or a 4 wrap 26ga around the little blue screw driver that came with the kit should get you your .5. If your really set on using the 28ga then twist two wires together...using a drill ensues the tightest twist...and a 4 wrap 28ga twisted coil will give you your .5.

Www.steam-engine.org is a really good website for coil building should help you with your future builds

If you want to increase the amount of vapour you need to increase the surface area of the coil. If you are using a regulated mod you can just add more wraps to your existing coil and bump the power up. Going to 26 or 24 AWG would increase the surface area of the coil and reduce the resistance. You need to make sure that your mod / battery can handle the extra current draw. The thicker wire would take longer to warm up as there is more mass. You can't really go by resistance and voltage or power on their own you need to take into consideration the thickness of the wire. A one ohm coil with 28 AWG will be much hotter and warm up faster than a one ohm coil made with 24 AWG at the same power setting.
if you use www.steam-engine.org you can get an idea of how hot the coil will using the heat flux number (higher is hotter) and the heat capacity number (lower is faster) on the coil wrapping tab.
Good luck!

Yes, some thicker wire will lower resistance for the same wraps. But the twisted 28s is a good idea. I build twists all the time.

I use 26 gauge almost exclusively. I also use 2 mm internal diameter coil.

8 wraps gives me a resistance of .79-.84 ohm. More wraps means more surface area to generate vapor.

With that diameter the resulting wick is just right to go to the bottom of the juice wells in my Silverplay Nano, Goblin Mini, or Kayfun Monster.

hey, guys thanks for the useful info. Just another question... have kind of effect will changing the size of the coil have? because currently i'm using the small blue screw driver which comes in the kanger subtank mini.

Changing the size of the coil in what aspect...such as the inner diameter...or the size of the wire? The smaller the inner diameter of the coil "nano coil" the hotter the coil will ramp up, and it produces a bigger throat hit and i different type of flavor, some also tend to not wick through the coil with these do to it being pointless because the coil tends to get so hot that the wick will just burn through or not be able to wick juice through in the first place. so they place a bed of cotton underneath the coil... I tend to get more flavor out of a smaller inned diameter coil, such as a 1.5mm inner diameter 24ga kanthal coil. you tend to have more wraps which creates more surface area and it also forces the coil to stay hotter longer once it ramps up, which tends to produce a more profound flavor to me. You can sometimes get the same desired effect with a smaller gauge wire due to it heating up quicker.

add another wrap or 3.

wait.....
if you are vaping 4.2 volts at 0.5 ohms, you are already vaping at 35 watts.

Yes, the size of the coil is important. The famous blue screwdrivers might be quite small, I could check later.
(and compare the internal diameter to an original Kanger coil)

The Kanger coil is 2.5-3 mm.

The shaft of the little blue screwdriver is about1.9-1.95 mm. 8 wraps gives me a resistance of .79-.84. My GO TO coil. I use 26 gauge Kanthal.

Awesome. I don't need to go up 4 floors to the Vape emporium. Thanks!
