Ok, so I have a dual coil setup with 26 guage kanthal wire. Ive got 7 wraps each, and they both heat up evenly, I wick it, juice it, and it still catches on fire if I take more than a 2 second hit! Ive double checked the screws and all the connections, ive tried changing the cotton, making new coils, but none of it seems to work. Could it be my batteries? Any help at all would be much appreciated!!!
