Ocassional loud popping noise

[Irken623]

Started vaping 6 weeks ago to use as alternative from cigs. LOVE IT.

I'm familiar with all the typical sounds once you press the fire button (that light crackling noise). But occasionally while firing recently there'll be another louder pop on top of the other noises. When it does it I instantly get what feels like something shooting up through the mouthpiece and hitting my lip (very concentrated, as if it was a needle). And whatever it is, is hot. It's happened several times over the past 2 weeks or so. Can anyone tell me what that is?

It's juice boil-over.  It's a fact of life when vaping, unless you get a tank or drip tip with a blocker.  My Aromamizer has "spit-back protection" built into the drip tip and it works very well; others have other solutions.  Most of us just get used to it though.  It's more of a minor annoyance than anything.

Oh ok. Yeah it's just an occasional annoyance. Just couldn't quite place what I was doing to cause it. 

Thank you

Welcome to the forum! I wear a lot of lip balm these days, helps a bit with that sort of thing.

If you are talking about a popping that is accompanied by the small explosion feeling, this is usually caused by too loose wicking or parts of the coil having set and not touching the wicking, or if the center of the coil heats up a lot and the sides stay cooler. I hate it to happen and always try my best wicking so my coils deliver a smooth draw, but it can still happen occasionally. If it happens frequently I'd change the coil or re-wick it.

My ideal coil sees a continuous stream of loud popping, like a machine gun 

The pop is a delayed nucleation, like when you boil water in the microwave.. it doesn't 'fizz' until you pull it out but somtimes it pops in one big hot bubble. Same thing is happening in the coil. Like Peter k said, it's all down to wicking.
