I will point out again you do not need flame to burn something. You can burn your dinner, and never have it on fire. Let me show you what happened to my friend's atomizer when he turned it up to 6 volts. A full wet cartomizer recently filled and was
vaping good at 3.2 volts. I told him not to, but he wanted to see, and the duel coil 3.0 ohm device blew one coil. He got a nasty hit, but then it still vaped on the one coil. Since it now had a poor taste he agreed to cut it open to see what happened. It seems the coil got hot enough to melt the tube "wicking" material around it and burn some of the wicking fabric as well before popping the connection of the coil itself. Since the coil was surrounded by
juice I would also have to be concerned if any juice was burned as well. Remember vaporizing in an enclosed space is not the same as doing it in the open where in can spread and dilute into the air. The coil is enclosed. If there was a small flash of flame or not we cannot tell from the outside. But I present this photo of the inside after the fact. It does look burned, and the one tube is destroyed. This was a brand new cartomizer filled and tested at 3.2 volts, and working fine with a 50/50 mix. Was it the 6 volts? Was it defective? Who knows but it is burned. Point made. Note the small part of the burned away tube left over on the left of the photo from coil number one, and the good tube still O.K. on the right from coil number 2
