To new and inexperienced vapers, rebuilding coils may seem like more hassle than its worth. However, as you gain more experience, you will almost certainly want to try it. Building coils is a complex process that involves design, math, engineering and most importantly, patience. Before we explain how this process works let’s look at the benefits.
Benefits of Building
While it may take a bit of time to understand the process of rebuilding coils, it comes with some instant benefits. The coil and wick can be made to suit your personal vaping style or the e-liquid used, maximizing flavor and providing a more fulfilling vaping experience. Building coils also allows you to produce more vapor, making it the best option for persistent cloud chasers.
When rebuilding atomizers, you need to learn how to stay safe. Firstly, read our blog on Ohm’s law. Understanding this common law of electrics is key to ensuring you don’t overload your e-cigarette. Only build coils within the recommended limits of your battery. Low resistance coils will put a strain on the battery and can be dangerous if the battery can’t cope with demand. Make sure you know the amp rating of the battery and whether your device is regulated.
What You Need
You’ll need several bits of equipment and types of materials to build a coil safely:
- Multimeter – capable of taking accurate resistance readings
- Wire clippers
- Micro screwdrivers
- Needle nose pliers
- A torch
The materials needed are dependent on personal preference. For instance, wicking material can be a variety of substances including ceramic, cotton, stainless steel, hemp or Ekowool.
- Resistance wire – typically Kanthal or Nichrome but there are more options
- Non-resistance wire – not all builds need this
- Wicking material
Selecting a wicking material very much depends on what you like, feel comfortable using and what works best in your device. Organic cotton is arguably the most popular wicking material. It is easy to use and to fit but is also simple to replace. If you can’t decide on a material, try a new one for each coil you build until you land on a favorite.
Resistance wire is the part of the vaporizer that heats up. There are a lot of choices for resistance wire but most importantly, you will need to select a material and a thickness. Kanthal is generally considered the best resistance wire because there is no adverse effect and it is highly resistant.
The gauge of wire refers to its thickness. Lower gauges are thicker wires and have a lower resistance. A higher gauge means a thinner with more resistance.
The secret to selecting the right gauge lies in the type of build you’re going for. For instance, sub-ohm coils require a higher gauged wire and less of it than a traditional atomizer.
Firstly, you will need to take the atomizer apart, this is an easy task that you will have done before when cleaning your kit. Atomizers have two or three small posts on top. The coil connects these posts and completes the electric circuit. The coil offers resistance for the flow of electricity and this turns into heat energy, vaporizing the e-liquid. As well as the coil material, the way the coil is wrapped will also influence resistance. There are many different ways of wrapping a coil.
You will need something to wrap the coil around; a small screwdriver will usually do the job. Wrap it tightly around the screwdriver and try not to leave a gap between each wrap. The number of wraps is dependent upon the resistance you’re aiming for. Ohm’s law is vital at this stage. Without it you could build a coil with too much resistance which can be dangerous.
The coil then needs to be evenly placed on the two small posts on top of the atomizer. Place the wicking material in a position where it is in contact with the coil. This is entirely dependent on your atomizer; some will simply pass through the coil but some are more intricate.
Once you’ve built your coil, check the resistance using the multimeter. If it is within safe operating range according to Ohm’s law, then simply rebuild the atomizer and you’re good to vape. The more coils you build the easier this process becomes and the more likely you are to build a coil suited to your exact needs.
