For this edition of our vaping masterclasses, we’re going to cover coil building with rebuildable atomizers. Today, you will not only learn how to build an atomizer coil, but you’ll also learn some of the necessary tips during the building process. Also, we'll start this class off with some required information about the different types of wire and wicking materials, wire and resistance, coil types, and coil builds.
- Round Wire: Round wire is most commonly used in coil building. The reason round wire is preferred over flat wire is that it requires a much smaller surface area, and is much easier to work with. Using round wire enables users to create different types of coil builds that can not be achieved with flat wire.
- Flat Wire: Flat wire is used less often with coil building since it requires a larger surface area and isn’t as easy to work with. Most users who use flat wire are creating unordinary coil types or are using Genesis style rebuildable atomizers.
Wire & Resistance
Understanding wire and resistance are one of the most important parts of coil building. Without this knowledge, you’ll be lost each time you build and coil, and will be left guessing the results of your finished build.
- The higher the number gauge wire, the higher resistance that wire is, and the thinner that wire is.
- The lower the number gauge wire, the lower the resistance that wire is, and the thicker that wire is.
- Example: 28-gauge wire will have a higher resistance and will be thinner around than 24-gauge wire.
- Single Coil: A single coil is where only one coil is being used. Single coils are more commonly used because they’re much easier to install than dual coils. Single coils are also easier to understand the resistance created.
- Dual Coil: Dual coils are more commonly used because they double the amount of vapor that can be produced and are believed to offer a more intense flavor with e-liquid. With dual coils, to understand the resistance, you’ll need to split the resistance in half of what the single coil’s resistance is.
- Example: If your single coil is coming to 1.0ohm, your dual coil will come to 0.5ohm.
- Macro Coil: A macro coil is typically a larger sized coil that has space in between each wrap. The wraps do not touch in this coil type.
- Micro Coil: A micro coil is where the coil wraps touch throughout. Some people refer to this coil type as a “contact coil”, where the coil wraps touch one another.
- Nano Coil: A nano coil is a lot like a micro coil with the wraps touching throughout. However, what differentiates the two is that a nano coil is much smaller in diameter. A nano coil is typically 1.4mm or below.
Many coil builds that have different names and are built differently. The above coil builds are just your standard build formats. These build formats are often applied to other coil configurations.
- Example: Twisted 28 “Macro” Build - This means the particular coil build has wraps that are not touching one another.
- Example: Twisted 28 “Micro” Build - This means that the particular coil build has wraps that are touching one another.
Wicking Material Types
Wicking material is required when using rebuildable atomizers. Though the wicking material can be used in many configurations, it is also meant to act in the same way: to supply e-liquid to the coil. The wicking material is what absorbs the e-liquid and distributes the e-liquid evenly across the coils. When coil building, using the right wicking material for the right application and applying the wicking material can make or break your setup. It must be noted that the wicking material is just as relevant to your setup as the coil itself.
It is important for you to understand which wicking material you should use for which rebuild atomizer. Some materials work best for certain rebuildable atomizer types, and some are universally applicable.
- Silica Wick: Silica wick works best for atomizers that are wicking liquid using gravity. Eg: Silica wick is not the best option for use with a "Genesis" style rebuildable atomizer (while it will still work), there are better options for use with reverse gravity atomizers. One of the characteristics of silica wick is that the taste tends to be average and the wicking volume (while it will depend heavily on size chosen) is accepted to be one of the best. Silica wick is the choice material for many of the stock atomizers built around the world because of its material properties.
- Stainless Steel Mesh: Many vapers that use genesis style atomizers use stainless mesh due to its claims to have the best flavor and vapor production. While this may prove true for some, we have yet to see stainless mesh produce as clean of a flavor as Silica or Organic Cotton with one catch, Genesis atomizers. This type of wicking material is the #1 choice of genesis atomizer owners because it works best with these kinds of atomizers. The downfall with stainless steel mesh is that it has to be heavily oxidized before use because, as you know, stainless is conductive and will create a direct short if not properly oxidized.
- Organic Cotton: This material is only recently being used by many rebuildable atomizer users and produces great flavor and vapor but has one major drawback, it's very flammable. For users that choose to use organic cotton, you have to ensure that you are keeping that wick saturated with e-liquid completely in order to prevent accidental ignition of the wicking material. You have to make sure you aren't running this material dry and DO NOT DRY BURN when using organic cotton as your wicking material. As long as you are making sure your wicks and coils well saturated, you will get an outstanding vaping experience with this material on gravity fed rebuildable atomizers and dripping atomizers. This material is not recommended for Genesis style or top coil style rebuildable atomizers.
