MasterClass: Coil Building

 Posted by in Beginner's Masterclass on April 17, 2015 .

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 a coil, but you’ll also learn some of the necessary tips during the building process.  In addition, to start this class off on some required information, we’ll be covering the different types of wire and wicking materials that can be used with coil building, as well as sharing information on wire and resistance, coil types, and coil builds.

Wire Types

Round Wire: Round wire is most commonly used with coil building.  The reason why round wire is more preferable 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 also 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 is one of the most important parts to 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.

Coil Types

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: A dual coil is where there are two coils being used.  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.

Coil Builds

Macro Coil: A macro coil is typically a larger sized coil that has a 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 actually 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.

There are many coil builds that have different names and are built differently.  The above coil builds are just your standard and main build formats.  These main build formats are often applied to other coil configurations.

Example: Twisted 28 “Macro” Build - This means the specific coil build has wraps that are not touching one another.

Example: Twisted 28 “Micro” Build - This means that the specific 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 important 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 by means of 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 generally accepted to be one of the best. Silica wick is the choice material in many of the stock atomizers built around the world because of it's material properties.

Stainless Steel Mesh: Many vapers that use genesis style atomizers use stainless mesh due to it's 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 types of atomizers. The downfall with stainless steel mesh is that it has to be heavily oxidized prior to 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 nicely in order to prevent accidental ignition of the wicking material. Basically, you have to just make sure you aren't running this material dry and absolutely DO NOT DRY BURN when using organic cotton as your wicking material. As long as you are making sure your wicks and coils are nice and wet, 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.

American Made E-Liquid

The Story Behind Our E-Liquid

We manufacture a very specialized line of USA E-Liquid that has been custom formulated to work flawlessly with your personal vaporizer. We source all of our ingredients from within the USA and pay very close attention to even the smallest details when choosing them. We care about our customers to the fullest extent and refuse to sell our customers any product that we wouldn't use ourselves. Our usa e-liquid is mixed with the highest level of accuracy using ASTM or NIST traceable measurement equipment to ensure both quality and consistency with our e-juices.

Texas Select Vapor is also a certified member of the American E-Liquid Manufacturing Standards Association (AEMSA). Being a certified member of this association means more than just having a seal, it means a commitment to our customers and consumers nationwide. By following AEMSA standards, our manufacturing process follows strict guidelines for e-liquid manufacturing and focuses on many practices consistent with cGMP.

We feel that choosing USA e-liquid from the numerous vendors that are online can be a tricky process to say the least. The majority of our USA E-Liquid flavors are mixed in a base of 50% Propylene Glycol (USP) and 50% Glycerin (USP) to provide the best of both worlds in e-liquid wicking and vapor production. We also offer the ability to customize your e-liquid with us. If you feel that you have tried a flavor in the past that wasn't quite strong enough, no problem, you can add a flavor boost to help the flavor better come through and appeal more to your taste buds. E-Liquid or E-Juice flavors can be quite subjective and while we cannot guarantee that you will absolutely love a flavor the first time you try it, we can promise you that the highest level of accuracy and thought has been put into each and every e-liquid flavor that we offer.
