I fried a KR808D-1 cartomizer so i decided to gut it and see whats inside.
Yellow - wraps everything inside it. Its the "fluffy" filler
Green - wraps everything inside it. kind of like teabag paper
Red - the wire. thicker one is the wire you see looping down to the center
Red(thin) - the heating coil wrapped around a stiff "string" made of fiber
Top Box - fiber tube. i think is made of the same material the coil is wrapped around.
Bottom tube - metal
gray line - line of sight. when you look in to the hole
White area - open space
Thoughts:
When you vape and feel a small spot where it gets warm thats the side where the coil is. So I would think it would be best to have that side down when refilling the carto so the liquid will run right to it. Keep this side down if you want to let it soak. When you feel that side get HOT, not warm, mostly likely the coil has already BURNED a hole through EVERYTHING.
