so, i have a sigelei 150w with a velocity clone rda. i am building dual parallel 6 wrap coils with 26 guage kanthal A1 (my multimeter reads 0.2 ohms), and some cotton from my local vape shop. my problem is, sometimes i do this build and its vape is as smooth as can be, sometime its the opposite and its crackling and popping and its usually minor IF i only take a quick drag, if i take too long of one it will pop REALLY big and makes me nervous about inhaling the flying hot liquid and burning my throat. just today, it happened, it popped a big pop, and a little spec of hot liquid hit the back of my throat and burned it, it was nothing serious, but it still hurts, and is still dangerous i believe. my question, why are my builds sometimes smooth and sometimes not...is it something that im doing when building the coils, or cotton. or one thought that crossed my mind what juice i use.
