Even if you’ve only been vaping for a short time, you’ve probably already experienced coil burn out. The unpleasant taste of burning material is difficult to miss.
Vaping devices work by vaporising e-liquid with a heated coil. E-liquid is absorbed into a wick made of cotton or other absorbent material, the soaked wick is then heated when the coil is fired, vaporising the juice and creating a cloud of vapour.
But if the coil is fired when the wick is dry, or only partially soaked, then it can burn, creating the unpleasant taste associated with coil burn out. As well as burning the wick, firing the coil without enough e-liquid in the wick will overheat the juice, adding to the unpleasant taste.
Wicks and coils wear out over time and need to be replaced, but there plenty of vaping practices that can prevent burning out too quickly.
Priming Coil, etc.
One of the easiest ways to reduce the risk of burning your coil is to prime it before use. Priming involves making sure that the wick has soaked up enough e-liquid before you start vaping. If you take the time to prime your coil, then you won’t be heating a dry or half-dry wick the first time you vape.
It can be easy to forget about priming, especially if you’re in a hurry or are new to vaping. But simply allowing the new e-liquid to soak into your wick can make a big difference to preventing your coils from burning out.
Priming can be done quickly on some devices, by exposing the coil and adding a couple of drops of e-liquid directly to the wick. Alternatively, waiting a few minutes after filling the tank should give the new e-liquid enough time to soak through into the wick. And closed vaping systems, like pod devices shouldn’t need priming at all.
Don’t chain vape
Avoid rapidly and continuously drawing on the atomiser if you want to prevent your coil from burning.
If your wick doesn’t have enough e-liquid in it then it can burn easily, and the wick needs a little time between firings to soak up more juice. Most vapers won’t notice that this is happening because average use gives the wick plenty of time to recharge. But chain vaping will drain the e-liquid from the wick faster than it can be absorbed.
This is even more noticeable if you chain vape for longer sessions, leading to a dry wick that can quickly burn out.
Top up the tank
This simple tip can make a lot of difference when it comes to preventing your coil from burning. When your tank is almost out of juice it becomes harder for the wick to soak up more e-liquid which makes it more likely to burn out. Keeping the tank topped up and not vaping with low levels of e-liquid will make it easier to keep the wick soaked with juice and prevent coil burn out.
Some vapers will tip the tank when the e-liquid is running low to try and encourage more juice to soak into the wick. But it’s more reliable to either top up the levels by adding more e-liquid or emptying out the tank and start fresh.
Another simple way to reduce the risk of coil burn out is to lower the power settings on your device.
Higher power settings create more vapour by vaporising your e-liquid faster, but this also means that your wick is being drained faster. If the power settings are too high then the wick can dry out faster than it can soak up new e-liquid, causing coil burn out to happen more rapidly.
Loss of flavour is a warning sign that you are vaporising your e-liquid faster than the wick can soak up more. Taking longer breaks between drawing on your device can help reduce the risk, but lowering the power settings can be a better solution in the long run.
Using a vaping device with temperature control is another way to avoid coil burn. Temperature control is a more high-tech approach to the problem as it monitors the temperature of your coil to prevent it from overheating the wick.
Temperature control vaping allows vapers to set a maximum coil temperature. The device will measure changes in coil resistance caused by temperature and stop the coil from becoming too hot. This means that temperature control will prevent vapers from trying to vape when there isn’t enough e-liquid in the wick.
Gunking is another problem that can lead to burning out coils. Instead of being completely vaporised, some e-liquids leave behind a residue that gunks up the wick, making it harder for the wick to absorb fresh juice.
Sweeteners are often the cause of gunking as e-liquids containing a lot of sugar can caramelise. But other ingredients and flavourings can lead to gunking too, darker juices are generally more likely to gunk up the wick than clear ones.
Using e-liquids that don’t gunk up the wick as easily can reduce this problem. Although some vapers choose to replace or clean the wick frequently to get around the problem of gunking.
