I recently got the IGO W6, and built it with a quad 24 gauge kanthal coil build, at .2 ohms. I followed rip trippers video and mimicked it exactly. It was fantastic, it was warm, big clouds, great vapor. I have it on a Copper Nemesis style mechanical mod clone. I also have it with a Sony Vtc4 to power it. It was great for a few days, I do not think this has anything to do with it, but I will include it because it happened in close time proximity to the issue, a ordered and installed, .925 silver coated contact pins, BOY it hit like a train after that. Some time after one of my vapes turned out horrific. The smoke didnt even taste like anything, it burned the inside of my mouth, not from heat, but harshness of vapor. Left a terrible taste. I removed the cotton, cleaned the coils, reinstalled them, threaded fresh cotton, and it was fine for 2 or 3 vapes. Then it did it again, when a friend of mine was watching. According to him, he could see a coil through one of the airholes. It lit up bright orange when we took of the cap, and fired to watch. It was normal. Cant tell the issue. it only does it sometime, I retired my w6 until i figure it out. Im scared to try to rebuild new coils, or whatever and vape on it again until i know for sure. (its that bad) I couldnt find any shorts. My other dripper, the magma paradigm, fires without error. The strangest thing atleast to me, is that coils dont (Normally) get orange when they have cotton, and juice running through them, all heat is diffused to the vaporization. Only when you dry fire them after installing (to detect even redness and resistance) do they get that hot. So what could of cause them to so hot that they turned red even under load. I cannot recall for sure, this is a maybe, ( as i was overtaken by the horrible burning) there may have been a subtle pop when it happened. I have searched everywhere and found nothing. Any thoughts?
