What atomizer are you guys talking about?
As for the first post: it is normal! The juice is burning, not the wick. This happens right before the wick is all out of juice.
When I make a new coil on my RBA I drop a few drops of e-liquid on it and dry burn it until it catches on fire. Let the fire burn out and repeate the process 2 or 3 times. I do this to clean my wick since I don't torch it with a (butane) lighter.
So, if your wick is well saturated with liquid there will be no fire.
BTW after around 10-15 seconds of dryburning the fire starts, so there are no problems whatsoever (if you have juiceflow

)
