How to Build Vape Coil-Vaping 101

If you are going to or just enter the world of rebuildable atomizers to do-it-yourself (DIY) and enjoy the process, vapers may have a question: how to build a vape coil? Here we are trying to give vapers who are beginners a guide to show step by step.

How to Build Vape Coil-Vaping 101

Before we start to build a coil, what vapers should know is the material and types of heating wires and cottons.

First of all, let’s learn some information about heating wire. Most packages of heating wire use ga or feet as unit of diameter. Here in following are some common diameter:

Second, we shall have some knowledge of resistance.

Resistance is a measure of the opposition to current flow in an electrical circuit. It is measured in ohms, symbolized by the Greek letter omega (Ω).

The relationship between current, voltage and resistance is expressed by Ohm’s Law.

Ohm’s Law: Current (I) = Voltage (V) / Resistance (R)

According to the ohm’s law, the resistance increase when current decrease if the voltage stays constant;

The resistance decrease when diameter increase if the heating wire in same length;

The resistance decrease when length decrease if the heating wire in same diameter;

Therefore, the length of the heating wire is proportional to the resistance; and the diameter of the heating wire is inversely proportional to the resistance.

Or you can understand it as following:

The wire resistance of vaping with wattage between 0.2 - 1.0Ω is for DTL flavor (beginners do not try resistance under 0.2Ω when you cannot sure if the battery accept it); resistance between 1.0 - 1.8Ω for MTL flavor.

The wire resistance of some with temperature control is always between 0.1 - 0.2Ω.

What You Need To Build Coils?

Here is a tool list to make a coil:

1. Heating wire - we recommend 22 - 30ga wire for beginners. And the commonly materials includes Kanthal, Nichrome, Stainless Steel, Nickel and Titanium.

2. Wire cutters

3. Scissors- cut wicking materials

4. Tweezers

5. Small coiling tool- can be a metal rob or screwdriver

6. Wicking material such as organic cotton

7. Screwdriver - always included in vape atomizers’package

8. A Rebuildable Atomizer - Dead Rabbit V2 RDA features a ‘Rabbit Ear’deck, making cutting coil legs easily, which is friendly to beginners

9. An ohms meter or resistance detector

10. Your favorite e-juice

Steps to build coils

After all tools prepared, let’s start to build it!

1. Cut the heating wire with length 3 - 5 inches

2. Wrapping

You can wrap the coils via both screwdrivers and coiling tool. Contact coils are recommended for beginners because spaced coils are much difficult than contact coils. And if you want to know more, you can read how to choose spaced coils or contact coils.

Besides, wrap coils by coiling tool will be easier. It will give more systemized and elegant wraps which are not possible if you do it by hand or manually. It always has 6 wraps.

3. Installing

Now you can install the coils in RDA. Loosen the screws on RDA’s build deck and you do not need to remove completely. Set the coil legs in to post deck (make sure one in positive and another in negative) and tighten the screws. Cut the extra coil legs by wire cutters.

4. Check Resistance onOhm Meter

You will need to check your RDA with installed wire for short-circuits. For this, you need an Ohm meter or a resistance detector. It will protect yourself.

Install the RDA on meter and check the resistance. Check it if it match your target resistance is above 0.2ohms.

However, if a difference is seen, check if the post screws are tight or not, and the coil must be touching the post. Meanwhile, checking these posts will adjust many problems related to it.  

5. Testing Firing

Now your coils are installed correctly and then put on to a mod. You should fire the new coil before wicking. Press the fire button to heating the coil which will help to remove the rust and oxidize coil. Meanwhile, you can adjust the coil to heating evenly by tweezers.

6. Wicking

Now it is the wicking time. There are many types of wicking materials, including Organic Cotton, Silica Wick, Ceramic, Rayon Fibers, Ekowool Wick and Stainless Steel Mesh.

The most recommended is organic cotton.

There are organic cotton pads or sheolace cottons for option. If you are fresh to wick, sheolace cotton will be more friendly that just thread it carefully in RDA. There has Hellvape Cotton Travel Set for you.

Or if you like other types of cotton, tear off a piece of a suitable size, then pass it through the heating wire, and align the two sides. Use scissors to cut overhangs or extra wicks then put them into e-juice holes. Finally, drops your favorite e-liquid on the wicking.

7. Final Testing

Once you finish all above, check the RDA with ohm meter once again to make sure the resistance is ok.

8. Vaping with it!

Well, if you finish all, congratulations that you are successful! Now just install the RDA on a mod and enjoy vaping.

It may be difficult for some beginners to build coils. But just need more patient, you will have a perfect coils after several attempts.
