What is a Dry Burn?
A dry burn is different to a dry hit. A dry burn is a method of preparing a coil before using it. To clean a coil before using it vapers fire the atomizer to make it glow red. This burns off any old liquid or anything on a new coil you don't want to contaminate the first drip of your new juice.
What is a Dry Hit?
A dry hit is something every vaper fears. It is when you dont have enough liquid to saturate the wicks and when you inhale you get a burning taste. It burns the wick and you will more often than not have to replace the atomizer or wicks if you every want a clean taste from your liquid ever again.
To avoid getting a dry hit make sure you don't let your e liquid level get too low. Plenty of liquid in the tank means plenty of liquid for the wicks.
