Gauge

[Bmccoy722]

Im new to vaping and I was wondering the different gauges of wire determin the number of wraps

Hello and welcome to the forum @Bmccoy722. Glad to have you here!

The Ω (resistance/ohm) of the coil is determined by these 3 things:

1. the gauge of the wire
2. the # of wraps
3. the size of the tool you are using to wrap your coil on

Steam Engine can help you when rebuilding.

Partially, yes. The number of wraps needed is also determined by the target resistance you're shooting for, the inner diameter of the coil you want to build and the length of the legs on your coil. As Susan says, check out Steam Engine and play with it some to get a feel for how the different variables affect your builds.

Thank younfor ur help guys and another question whats a good resistance to shoot for I hsve a ohms meter and the build I just did read .34 that good

A given length of wire will have a certain resistance. The thicker the wire, the lower the resistance. Coiling the wire allows this length of wire to fit inside your atomizer.

Eg.
Target resistance ~ 1 ohm
26AWG wire total length 89mm, wrapped 8 times with an internal diameter of 2.5mm
(If you made the internal diameter of the wraps 3mm, then only 7 wraps would be required.)

Target resistance ~ 1 ohm
24AWG wire total length 141mm, wrapped 12 times with an internal diameter of 2.5mm

If you are aiming for a lower target resistance then you will need to use a thicker wire.
If you are aiming for a higher target resistance then you will need to use a thinner wire.

Depends on what delivery device and power device you're using the .34Ω coil in/on, and of course the battery(s).

If you are aiming for a lower target resistance then you will need to use a thicker wire.
If you are aiming for a higher target resistance then you will need to use a thinner wire.

Do you only use one length of wire for building?
I have built .8ohm - 2.0ohm coils All from 28ga.
Rebuilt many oem heads with 32ga at 1.5ohm to 2.2ohm

I have quite a nice .068 Dual coil 26ga. 2.5id TI wire TC tank going atm.

So far, I have read nothing to dictate Advising this Op on Safe builds as I have no knowledge of equipment being used.
