One of my attys (510) just started melting my 3d (!!!) cart in as many days. The first one I thought I overheated, so I got more careful with temp. The second sent me searching through threads, and I found the one on orienting the cart, so I started doing that. The third was very carefully aligned, but still started melting. 
And no, I'm not sitting on the button, my drags are no more than three to five seconds or so, and the atty is comfortable to touch, not too hot on the outside. It seems to be happening on the second puff. I usually take three puffs in a row, then rest. The first one is fine. The second one tastes of burnt plastic...
I checked - the little doohikey in the atty is centered an'all.
Any ideas? The smell and taste is awful, acrid and burning, and it can't be good for me and all that. This is an emphatic YUCK.
