What gauge SS for TC

[6steelstrings]

I have a smok X Cube Ultra that does TC, so since I have never done TC coils before, I thought I would seek out some help. I will be building on a Geekvape Griffin 25 so I have plenty of deck to work with.

I am thinking 24ga but I really am just guessing. What would you suggest?

I do a dual coil with 28ga SS 316L, 6 spaced wraps around 2.5mm bit
for a resistance off ca. 0.3 Ohms.
Of course you could fit bigger coils, but no problems with leaking for me.
I use Rayon (Cellucotton) as wick.

Btw... Steam Engine main page is your friend

SS has a lower resistance than Kanthal. A 24G wire might well be below where you can build and still end up with a reasonable resistance, especially in a dual coil build. As the resistance isn't even all that important if you're using this for TC, I would simply build to what is likely to work best with you mod. If you're using 316L SS, which has a very low TCR, a build with a total resistance of 0.3 ohm or higher will likely work best. On dual coil builds, I typically use 28G with a 3 mm ID and a total resistance of ~0.5 ohm. For example, building to an example 1 ohm single coil setup, 24G Kanthal would require ~10 wraps on a 3 mm jig, while 24G 316L would require a coil with over 20 wraps.

Of course as you can use SS in wattage mode as well, you can keep that in mind when deciding what resistance you're going for. I keep 26G and 28G SS in my stock of wire.

Thanks for the replies. I am going to order some 26ga SS 316L from Amazon.

The only detail that does bug me with SS's low resistance is how it impacts battery life. That's one of the details I do worry about. Going higher in gauge is a solution but then you start getting into buildability issues... dunno balancing act

The watts you've set the mod to determine the battery life, not the resistance. However, beefier coils and thicker wire usually require higher watts and that results in lower battery runtime.

Hmm.. I'm no expert, but I thought a lower ohm build pulls more amps. Couple that with a potentially lower heatflux and thus increased wattage setting to accomodate, it in all drains a battery a bit faster.
I have two RTA's with different builds. One has a 28g .75ohm build and the other a 24g .2ohm build. I mostly run them both @ 30watts. Using them during one of my typical work week routines the .75ohm will last me from 7a-10p consistantly. The .2ohm build rarely makes it past 8p. That's not even accomodating for the lower heatflux the 24g/.2ohm has. If I do that, say I'm really wanting my Vanilla Custard to pop with flavor, the battery won't make it past 6p.
Dunno, I'm not fluent enough in all this lay this all out mathematically, but it seems pretty real to me..

Amps pulled on a regulated mod have nothing to do with resistance. Equation is I = P/V where V is the battery charge (not what the mod delivers). Watts are watts on a regulated. But, yes, if you have a lower resistance wire, you will (probably) run it at a higher wattage to get vapor/flavor where you want it. So you'll most likely get less battery runtime the lower you go.

I'm running dual spaced 26/32 gauge 316 ss claptons, 0.206 ohms at 80J and 500F in my crius plus on an IPV5 with the manual TCR set to set to 0.00092.

I'm getting a fantastic vape from this with no hint of a dry hit.
Not sure how xcube performs with ss temp control or if it has a manual TCR mode like the IPV5 though.
