So i'm somewhat experienced with vaping but no expert. I just recently bought a new Plume Veil RDA and wrapped it. I also just switched to 24 gauge from 26 so the coils I wrapped were a bit larger than usual. I'm not sure the brands or names of anything else on my device but it is an unregulated mech mod. After vaping for about 15 min out of the box I hit it and after a heard a very loud crackling sound. This wasn't your average juice crackling off the coil it was much much louder. I was wondering if maybe it was because the coil touched the outer walls of the RDA. I'm not sure what to do or if i should stop vaping and rewrap coils or what. Could someone advise me? Ask about any other info if you need it.
