It is important to keep in mind that electronic cigarettes need some care to last for a long time. Cleaning is something necessary to be able to solve the problems that may arise over time, thus avoiding problems such as burning the coil.
If the heating element burns out you will notice a slight burnt taste and even your cigarette will not produce the same amount of vapor as usual. It may be that this burnt taste lasts for a while once we have changed the coil, it usually disappears after a few puffs, if by chance this unpleasant taste continues, you would have to change the liquid.
But when to change the coil of the electronic cigarette? As indicated in the previous paragraph, the coil should be changed when these problems are noticed. But what should we do to avoid burning the coil?
When we change the coil of the electronic cigarette, the wick must be completely soaked. This process usually takes about five minutes so that the first puff does not taste burnt.
Another problem that tends to burn the coils is to vape with more power, this causes more liquid to be used for each puff, negatively affecting the coil. The tank is another fundamental part since it contains the e-liquid, it is important to have it full, because if the amount is low the wick does not absorb enough.
E-liquids containing a high percentage of vegetable glycerin usually cause problems in the wick also affecting the coil, so it is advisable to buy less dense e-liquids.
As you can see these are some of the steps to follow to prevent the coil from burning, but remember that it is important to know when to change the coil of the electronic cigarette, since a burned coil can ruin the vape.
