I made my first coil on the ZAP last night, and while pulsing it into submission got it to where it was firing on all cylinders, I used some 34 gauge I had laying around to play with, all seemed well until I put fluid to it and then it makes good flavor but the throat hit was terrible. I pulled the cap back off and when I fired I saw the legs to the coil were glowing red hot, was still producing vapor. Is this normal or is something off?
