Whereas setting the wattage lower, will lower the chances of the coil burning. The coils themselves usually have an operating range printed on them. Keeping the power within this range will help to ensure the longevity of the coil.
By reducing the power you’re also reducing the length of time it takes the wick to reabsorb the eliquid which means that you can vaporise more frequently without the fear of burning the wick or coil. Chain vaping is when you take successive hits of your vape in quick succession. This can be an issue as not all coils are created equally. Some will “wick up” (saturate the wick) a lot faster than others meaning the time between hits is lessened. Taking just 15-20 seconds between hits allows the coil to cool and the wick to saturate or “wick up” this will improve the coils longevity and create a pleasant vaporising experience for the consumer. Most chain vapers are newly converted tobacco smokers and as such they are looking for that thick, heavy hit and consequently too often set the temperature too high and try to inhale it like they would the cigarettes they used to smoke – short quick bursts, this will quickly dry up and damage the wick as it won’t have time to wick up between hits. So you’ve spent lots of money on a top of the range vaporiser, you keep it immaculately clean, replace the coils frequently and avoid the amateur mistakes of chain vaping and not priming coils, yet you’re still getting a burnt tasting vapour? It is likely then that you’ve been using a cheap E-liquid. Cheaper liquids are often produced using a higher ratio of VG to PG making them thicker which increases the likelihood of clogging the coil which can also lead to the wick drying out and burning. Using an ejuice with more PG should help reduce clogging as it will be thinner.
These cheaper E-liquids also tend to contain sweeteners. The sugars in these sweeteners can caramelise and block up your coil leading to it burning out. Possibly the most common reason for experiencing a dry, harsh vape hit is having an empty tank. Attempting to vape an empty cartridge will result in a foul burning taste and quickly dry up the wick and can potentially destroy the coil. “Overcooking” the little remaining E-liquid can cause it to burn, which doesn’t taste too great. If you experience this then remove the wicks immediately as the taste will remain even once topped up. Hitting a fully dry cartridge or tank could potentially ignite the wick, setting it on fire. Keeping your tank topped up and ensuring that you prime it too will help you to avoid this common pitfall and keep you vaping with confidence. Interestingly, the weather can effect your vaping experience. The viscosity of your ejuices will change depending on what temperature they are stored in. Cold weather will thicken your ejuices and warm weather will thin them. The cold will cause more issues than the heat as the temperature will make a PGheavy mix act like a VG dominant combination. This will make the coil more prone to clogging as the E-liquid is thicker. Try to avoid leaving your vape exposed to extreme temperature fluctuations. Another common cause of burnt hits when vaping are hotspots on the coil which can cause it to glow an intense red as the excessive heat moves through it. Vaping on a hot-spotted coil can result in a nasty metallic tasting draw that will be hot and unpleasant. Hotspots cause burnt vapour regardless of the saturation levels of the wick. Throw away any wicks that have been burnt, as they will retain that unpleasant flavour and taste. Once you’ve identified a hotspot on your coil, there are two things you can do about it. You can get the coil to pulse evenly again by using a tool to “strum” the coil or lightly pinching it with some tweezers which will promote even distribution of heat across the coil. DO NOT attempt any repairs on the coil while pressing the on button unless using ceramic tweezers. The wick is responsible for vaporising the E-liquid in the tank. It is heated by the coil and then inhaled through the mouthpiece. Using too small of a wick will result in a poor vaping experience and can even cause it to leak.
Using too much wick is also a problem, having too much cotton increases the total area that needs to be saturated to work correctly and to avoid potentially burning out the wick. It also means that the time between vapes will have to be increased to allow the ejuice to be fully absorbed on to the wick.
So what are the key takeaways here that can prevent your coil from burning out? The most obvious message is that you always need juice in the wick when you vape, so it’s imperative that you maintain a relatively full tank of e-liquid at all times. Ultimately, this means that you should never “dry burn” your coils, as most wicks are made from cotton and will quickly become ruined if they’re heated without the adequate amount of juice to protect them.
