This is a "typical" micro coil build using Kanthal on a 13W (MTL) mod, my trusty Evic Vtwo.
I am building coils for years, but I still don't understand why it sometimes happens, and it happens often, especially when coils are a little older. (But otherwise look fine).
When I pre-burn a coil (which I do usually when changing wicks), only the first winding of a coil glows red and it takes a fraction of a second until the entire coil glows. I already tried to get behind this eg. suspecting that a coil might not be screwed on well, or that it's the coil shape or whatever. No idea. Most of the time when it happens I make a new coil.
I do not know whether what I see when I "pre-burn" also translates to actually using the vape. If that's so, it would mean that power on the coil, at least for a fraction of a second, is not evenly spread out but concentrated on a single winding. As if the beginning of the wire has a lower resistance than the rest.
Anyone an explanation for this phenomenon?
