22g Kanthal

[spitzer26]

So I got the evic vtc mini with turbo rda. and currently i only got 22g kanthal. on what build should i make ? how many wraps for it to be safe ? i dont want it blowing up in my face. i know its a regulated device but just to be sure. please help thanks

HI spitzer. I use this steam engine to figure out my builds. It's a good one to bookmark for later use :Coil wrapping

.2 ohms and up would be my recommendation. 60 watts at .1 ohms pulls ~25 amps which most batts can't safely do.

You're pushing a 60 watt mod with wire that big. A dual 8/7 wrap on a 3mm mandrel will bring you in at about .25 ohms. I wouldn't go much lower than that. Ask me, what you need is some 28ga wire to get coil surface radiation in a reasonable place and minimize time to vapor. With 22ga, I think you'll be shoving max watts and still be waiting on ramp up time. That's a lot of mass to heat with 60 watts. I hope you have a good battery.

Edit: building it single coil will be helpful, if you can adjust the air for it. You could shorten the coil a good bit to reduce mass.

22 gauge is pretty tough.. You're gonna want a lot of surface area with a large inner diameter if you want to stay within the limits of your battery.

If you're above .3 ohms, you should be fine. .22 is 20A at 4.2V, but it's good to have headroom in case there are fluctuations in resistance (which is pretty much guaranteed).

^As stated above, 22 gauge is gonna be a bit of a nuisance on the VTC Mini. Too much wire = large ramp up time, not enough wire = potentially dangerous. I'd suggest 26gauge if you can get it.

Invest in some 24 or 26awg wire.

As stated above, 20 and 22awg really takes to long to ramp up. Personally I use 24awg in my drippers, 26awg in drippers and my sub-ohm tanks, 28awg in my Kayfuns and other RTAs. Build to the strengths of the deck/device you are building on.
