Hello everyone! Just joined the forums and I'm having an issue with my zmax. I'm using an i clear 30 and a 18650 on it, and it seems to be getting very hot at the top of the lower threaded piece, basically right in the middle of the mod, only when vaping. I thought it felt hot with my hand so i put my lip on that area and pressed the button and it got so hot it felt like it would burn my lip. I am running it in between 4.5 - 6.0 watts usually, on rms mode. All the contacts appear to be clean, am I shorting it out or something?? I also noticed that sometimes the mod will make a funny sound almost like a zapping, u can only hear it with your ear up against it, and it only does it once in a while. Any help is much appreciated!! Thank you!
