Really must get to grips with TC!

[chykensa]

OK folks, help required!
I've recently picked up a couple of Subtank Minis from our good friend flavourtank, and I have a selection of NI200 wire. What are your thoughts on a Nickel build on a Subtank RBA which will work well on my new (and very lovely!) Koopor 200w (tongue firmly in cheek!) mod?
Is there any advantage to twisting the wire first?
Should I aim for a particular resistance, or is this a bit academic?

As always, your help would be gratefully received!

Not had any experience with the mod but when I had a subtank I used to use .25mm Ni, 9 spaced wraps around a 3mm bit to give roughly .2 worked well

I've been putting it off after reading about how tricky the Nickel coils were to make and the inability to dry burn them.

Am I right in picking up that stainless steel wire - that I notice several recent TC mods are capable of using - is more robust, like Kanthal?
Are there any other considerations / limitations with SS coils?

nickel is a bugger to coil, imho get a pack of horizontal coil Ni200 OCC heads to start off with, they last ages, and when dead you can recoil with a vertical coil as per the how to in the tips n tricks section, as the spaced coil wrapped round a machine screw is easier to coil and wick than a standard rta build imho..
avoid the newer vertical occ coil heads tho as they are not the same 2 part design which complicates the diy recoil.

chykensa do drunkenbum recommendation ,a good starting point for a subtank, don't know the mod so just make sure mod and atty are at same temp, lock the ohms if you have to on that mod then start low and work your way up to the vape you (hopefully) want.

wouldn't do twisted nor shoot for ohms, I only do on a mech, especially so for temp control. Look at the atty, it's juice flow and air flow limits and build a coil for that and the vapour volume you want, athough every atty will have its limits due to the latter.

You do need to get the ohms above the min for your device, I find twisted is easier to work with and prefer the flavour, but you need thinner wire probably 0.2 mm, I'm using 0.25 mm twisted ATM but the resistance is very low, too low for many mods. I dry burn all the time, just dark red not bright orange then wash the coils.

Twisted wire will make for a stronger and less pliable coil, sometimes it can improve flavour depending on your juice but it does require more power to run which in turn will affect battery life.
I use .3 NI200 non twisted in a subtank, 7 wraps around a 2.5mm former will give you around .12ohms and will fit the subtank base just about right

Pretty much my own Ni200 build for the subtank RBA, very little difference between 2.5mm and 3mm mandrel.

Twisted....I find it a bit too springy for the limited space, ok-ish on a dripper

[VapingBad]

Twisted stops being springy after a few heat cycles and then holds is form better than non twisted IMO.

Got two TC mods, tried both can't get it to work properly, chucked the Ni200 wire in the long grass, back to kanthal, problem solved.

I've coiled my Magma with 2x12 turns of AWG 28 (0.32mm) Ni200 on a 3mm mandrel.
Resistance comes out at 0.11 ohms.
The vape is good, but to me Kanthal has the edge!

Jim jevans - to be honest with you, I haven't yet had the time to experiment with Nickel wire, but I hope to have some spare time over the holidays, so will post here with my findings. I'm not surprised to hear yours though!

Twist the wire if you are only going to use one coil, otherwise just micro coil if using two. I own no mod that can cope with 2 x twisted coils, none of them will fire that low. As mentioned above you are going to need lots of wraps, Ni has low low resistance/m.

I have been using twisted dual Ni200 coils for ADV over a year, admittedly with a genny on a min 0.1 ohm mod (DNA40) as you need 0.16 mm Ni200 I told Vape Mesh Co at the time their wire sizes were too big, but they don't have a Scooby about vaping.  With the DNA200 I'm using twisted 0.25 mm in the Aromamizer, dual 2.5 mm 10/9 coils 0.056 ohm lovely and vape very well down to 355 F with 100% PG.

Personally don't like twisted NI200, didn't work for me when tried, makes no sense to me neither, space to stop contact and keep the readings accurate but twisting two wires together that will not be in full contact across is length is ok?
