I just got a new Kanger Unitank. I'm using a 2.2 resistance coil and a smoktec variable voltage battery. I pre primed my coil and flipped rubber cap up. The voltage I'm using is 3.6. I can only get dry hits it seems. I don't really know what to do. I'm pretty sure I didn't burn the new wick because I've had the voltage down so low. If anyone can help it would be appreciated.
