My Mutation X build kept catching fire on me! I would press the button on my Sigelei 100W and as soon as I did, Boom - Fire. Like, lots of fire shooting out the airholes, it was Crazy! It wasn't every time and it was very sporadic. Couldn't figure out why, so I removed the coils, had Quad 28 ga at 0.2ohms, and put on Dual Twisted (Twisted Dual 30 ga around 24 ga) for 0.2ohms and Caught fire Again!! Each time it happened I had the top cap on. I had 2 different juices in it, between the 2 different coils, and had 3 different wick setups.
Still have no clue as to why this was happening. Cause it was literally happening as soon as I pressed the button (i guess you could say, "right at fire up").
