It's okay. We get it. You just got a great setup, you want to stop smoking, and you want it all to work. You just have no idea on how its supposed to go together, and your embarrassed to ask. Maybe, the shop you got your equipment from didn’t tell you what you needed to know. Or even worse, you’ve been vaping for years and think you know it all but keep burning through coils (this is worse because by now you’ve wasted hundreds of dollars you didn’t need to).
By following these steps, you should be getting close to 2 weeks (or more) out of your coils. If not and you are following these steps, then the answer is easy: Inhale. Twice. As. Hard. Its really that simple. The coil needs you to pull harder to get juice into the coil and prevent it from burning.
You need a new coil whenever you start to get a burnt, acrid flavor, vapor production goes down or flavor production goes down. This should be around 1 coil every 2 weeks. with heavier usage this timeline goes down, with lighter usage it goes up. On average for a pack a day smoker you should be replacing your coils every 2 weeks. If you are not getting this life span out of your coils, then it comes down to user error that needs to be corrected.
You need to prime your coils from the inside out, do not put liquid on the outside of the coil or install the coil into your tank and let it "soak in." To prime your coils you need to hold them sideways then apply liquid down each of the holes on the top of the coil. avoid adding liquid to the sides of your coil as this will cause dry spots near the top and bottom. On some higher wattage coils (such as the T-12 for the TFV-12 Cloud Beast King) it can be beneficial to poke holes in the exterior wicking channels of the coil. if you do this you'll want to use a safety pin or push pin that is clean and sterile and only go about half way through the cotton, any more and you may have too much juice flow.
You need to use the correct wattage for your coil. each coil has a minimum and a maximum that it was designed to work at. to find the correct wattage you need to find the average of the low and high setting. if your coils are rated from 30 to 50 watts, you would want to keep your coils at 40 watts or below. the formula is: low wattage - high wattage = sum / 2 = result + low wattage = max wattage.
i.e. a coil with a wattage rang of 30 to 100 watts would be:
30 - 70 = 40 / 2 = 20 + 40 = max wattage of 60
You need to reduce your airflow. all tanks operate using a vacuum, if you are not creating air flow resistance you are burning up the coil. To start i recommend most people keep their air flow half way closed, although it varies from person to person. the 'sweet spot' is just before it starts 'misting' or 'spitting' ever so slightly, ease back a little from that point and you'll get a lot more flavor and save your coils.
When you vape, try to hold your setup straight up and down. When you tilt the device half (or more) of the coil is exposed to air rather than liquid. this creates dry spots that will cause your coils to burn out. this doesn't mean you have to be rigid and keep the device always straight up and down, it does mean pay attention to where your liquid level is. and make sure the juice flow channels on the outside of your coil stay covered in e-liquid.
