Phoenix RBA, Silica Wick, 32g Kanthal wire, getting hot spots

[TheHoochCow]

So yea as the title says I'm getting hot spots on my coils. I just entered the world of RBA's and I'm trying to get it down. But it seems every coil I wrap I wind up with hot spots which means my juice isn't vaping as well as it does on other attys like the heads in my vivi nova or my joye 510 atomizers. I use 2.5mm silica wick, I place it against a paper clip and wrap my coil around it and the paper clip and pull the paper clip out, I install it in the phoenix, check with multimeter and my vamo to ensure there are no shorts and that my coil doesn't have any crazy fluctuations in ohms. but when I put juice in and check the coil only certain coils are getting red hot and the others aren't lighting up at all which is hurting my vapor production, on a 5 coil wrap I'm lucky to get 2 of em to light up. Any tips?

no responses!? I am curious as to a solution myself!

try to adjust the coil a little bit while firing.

I've found that sometimes the juice itself will keep the coil from glowing red. Could be that the silica wick is not touching part of the coil, thus, not getting juice on it, causing it to glow when the others are not. Just a thought as i'm most certainly not an expert. Keep on tryin', you'll get it!

Try using something thinner like a needle.

FWIW when I use silica I expect to see NO glowing coils when being used, for that I would need to do a dry burn. The ones getting 'red hot' are the problem.

When you put juice in, there should not be any hot spots. There would be wet, vapor producing coils. Glowing hot spots on silica wicks are caused by no eliquid touching the coil. This can happen when coil is too big for wick (or wick too small for coil), so the eliquid never reaches that part of the coil. A hot spot could also occur if the wick is not wicking properly--most likely pinched tight, and eliquid cannot flow through it.

Getting a coil wrapped properly is not difficult, but it does take some practice. Too tightly wrapped is not good. Too loosely wrapped is not good.

I like vertical coils on my Pheonix. This way you can easily replace the wick. I wrap it around a screwdriver to size it correctly.

OP what version of the phoenix are you running? I have a V3 and I see this too, when I'm dry burning. I always test the coil/wick dry before I put juice in, get all coils glowing, then I vape for a bit and notice a really harsh hit and see more gunk on one or two coils. Then when I dry burn to clean it I see that only some of my coils get red hot. I haven't found a fix yet, but I just wrapped a micro coil running perpendicular to the posts(if that makes sense) and I'll see how that goes.

Could be that your positive and negative posts are a little loose. Move the wick ever so back and forth/up and down. Check that your coil isn't loose around the wick (not too tight either).
