Help with understanding coil gauge and wrapping

Recommended Posts

Try looking through YouTube of builds. Pbusardo and RipTrippers are two good channels to look for.

You deff need an Ohm meter or Multi-meter to test out your coils. You also need to know how much amps your battery can handle to know your ohm limits.

Some "standard" tools would be a torch to oxidize your wick and wire. Nail Cutters/Wire Cutters. Tweezers/Pliers.

A brief overview for wire. Kanthal A1 Grade is recommended.

The larger the number guage, the wider the wire

The smaller the number guage, the thinner the wire

Wide wires have less resistance

Thin wires have more resistance

So for example if you're aiming for a 1ohm resistance it'll take more wraps on a wide guage than it would on a thin guage

And all in all its all about experimenting, using a multi-meter or ohm meter. Through experience you'll see what works and what doesn't. You'll also get a general idea how much wrap will get you what reading ect. ect.

There is a good app for android that helps out with building coils.... It is called vapers toolbox. You can put in what gauge you are using and what ohms you want and it will tell you how many wraps. It will also tell you what wattage is equal to what voltage if you want to use a variable wattage device or vice versa. I would check it out it helps.

Unfortunately there isn't a Vapors Toolbox on iOS

Yes diameter will affect your ohm readings but if you get the right length of wire you'll get about your desired ohms

these readings are can vary but they are measured in ohms/inch

Guage | Kanthal A1 | Kanthal A | Kanthal D | Nicrome 60 | Nicrome 80

24 0.18 0.17 0.17 0.14 0.13

26 0.29 0.27 0.27 0.22 0.21

28 0.46 0.44 0.42 0.35 0.34

30 0.72 0.69 0.67 0.56 0.54

32 1.15 1.10 1.07 0.88 0.85

Thin wires have more resistance

So for example if you're aiming for a 1ohm resistance it'll take more wraps on a wide guage than it would on a thin guage

So for example, i like 3-4 layers of 2mm silica wick and 4-5 wrap of 30G

a similar equivalent in 28G would be 3-4 layers and 2-3 wrap of 28G or 5-6 wrap of 28G?
