So I've been vaping for about two months now and have learned a bit but never have I experienced something this frightening. I have a lt infinite with 6 wrap .22 gauge dual coil kanthal. I'm getting a .2 ohm resistance. I've been using this same setup for a month now and it's never caught Fire even with the cap off. The wicks were thuroughly soaked in max vg liquid (Id say 80% at least). I'm only hitting it on 75 watts. Took one hit and all of a sudden it made a boom sound and burned the hell out of my mouth. What caused this? How can I prevent it? Any help would be appreciated because I enjoy vaping but I don't want to inhale fire. I got lucky and somehow didn't burn my throat or inhale the fire.
