Temp limiting 1st anniversary

[VapingBad]

It is a year ago today that my vape life was upgraded when I got my first DNA40 wired up and vaping.  Looking at the first page of this thread I really loved the almost instant heat up, but still had the temp a bit high and not discovered that flavour revolution. I almost have to force myself to use Kanthal now, it's not that non temp limiting is bad rather that everything it can do can be improved with temp limiting & especially pre-heat. Sometimes it takes some effort to find the build, but newer devices that can drive coils that are much lower resistance has made that easier than it was 12 months ago, but many of us still managed then when there where no examples.

It is not a gimmick there is no going back for me even after that first day or two and a year on it is getting even better and I am even more convinced.  I know some people think it is just about avoiding dry hits and while it does do that we could avoid them quit nicely already and it would have been no more to me than the difference between one generation of atomiser and the next. I found the flavour, the cleaner flavour is often found by turning the temp down and sometimes this requires making larger coils to spread the heat over more wick if you don't get enough vapour at lower temps. I believe the cleaner flavour is about the max temp your liquid is exposed to and not the temp you are vaporising it at, think of burning food when cooking turning the heat back down will not remove the burnt bit. I am not trying to tell people they should be doing this just how I do it and want other's to get the satisfaction I get.

The other big benefit is the extremely fast heat up, especially with DNAs, but many people max the watts on other temp limiting mods to get a similar effect. It is the first thing that happens if I try and vape kanthal: impatience and longer inhales waiting for the omph to arrive, sounds dramatic, but that is how it feels to me anyway and has completely killed non temp limited vaping for me within the first couple of days.

But you can just use temp limited devices like VW devices: plug and play not concerning yourself with the extra setting and it is certainly nothing to be wary of that will force you to learn loads of new stuff and jump through hoops either.

YMMV but it is clearly not a gimmick or just of value to avoid dry hits.

Interesting post VB, does reducing the temp also reduce the build up of crud on the coils? I love my VT200 & looking forward to getting my Efusion. I'm using large deck drippers, with typically 13 wraps of .3 Ni200. The vape is lovely, but the coils go black very quickly. Usually have the temp set to 450 or so.

Over a few days I get a big build up of deposits on the coil, I do try and clean them, but on a single coil build it's usually easier to just change the coil. Juices are almost exclusively dessert flavours, custards & the like, so already prone to dirty coils. What sort of temp do you vape at on a DNA device?

Thanks - Bob

I think so, but it would vary between liquids, that changing colour in the wick is where I think that the liquid starts to change flavour and the more you can reduce that the more the liquid will taste like it would if you tasted a drop on you finger tip.  One way to think of coil vs temp is 10 wraps at 400 F will make more vapour than 8 wraps at 400 F, but it is sometimes hard to fit as many wraps in as you need and it can be helpful to go on SteamEngine to see if using thinner wire with more wraps works to spread the heat more.  You would be trying to get the heat flux lower, the little red, amber, green icon.  Thicker wire gives more contact area which is the thing that really
spreads the heat out, but it can be hard to fit in the space in the atty
and have the res high enough with many temp limiting mods. Because of the 0.1 ohm limit on DNA40 I used twisted 0.16 mm Ni to do dual coils and get enough wraps in, but with DNA200 I can use ribbon Ni.

I mostly vape at 380 F, the one exception so far has been new build ribbon Ni on a genny, but I am getting better at those builds and have them working well at 380 - 385 F.

Great Post!
So wot would you recommend for Me....vaping gunky NETs only, via Origen RDAs & Origenny?....

I get on well with mesh over ss rope, just dry burn without making glow now then steam clean or ultra sonic clean.  I find that the longer the mesh is in service including cleaning and the odd re-torching the easier it is as pulsing Ni like you do with Kanthal weakens it too much.  ATM I have 2 layers of #500 mesh over 3 mm ss rope & 6 wraps of 0.5 x 0.1 mm Ni200 ribbon and don't pulse it at all when re-coiling.  I use Hansen NET 100% PG liquid, not as gunky as yours, but still pretty demanding.

Thanks for that.
I think it's the comparative weakness of Ni that's kept Me off of trying TC (..that & being stingy re. buying more Gear!!!..) One day tho'...!

I've just started experimenting with TC and so far I have to say I'm impressed.

Firstly, tempered Ni isn't particularly difficult to work with... I'm by no means an expert builder, I've only been at this a few weeks, these were the 1st spaced coils I'd made but it wasn't as hard as I expected. Yes you need to take a bit more care with them, but it's well within my limited capabilities.

Secondly, it's a flavour revolution. I've tried 3 tanks now, and in each one the flavour is cleaner and stronger than when using kanthal, plenty of vapour too. I don't know if this makes sense to anybody else, but it seems a much more consistent, predictable vape.

This is just simple builds I'm talking about, single wire, single coil, using 0.28mm Ni, wicked with Muji cotton.

I'm sure there's a lot more variety available with twisted wire, or Hendrix, different wicking techniques, but that's all a bit above me for now.

But anyone who's been thinking they'd like to give TC a go but it might be a bit tricky or require a higher degree of skill, just give it a go, a simple start can have great results (taking into account mod limits and using steam engine to ensure builds are workable, obv.)

I'm quite the fan of the temp control used in istick TCs. Mainly because there is no wattage control when using TC - you set the temperature, and it fires a full 40W (in the case of my device) until it hits temp then throttles back. Basically a poor mans preheat. It takes one more tweak out of the process, which won't appeal if you like that, and a DNA200 in that respect it ain't! But the idea of just setting temperature to 430F and hitting Go is appealing to lazy gits e.g. me.

I think that Nickel unfairly got a reputation because people had got used to doing micro-coils with progressively thicker Kanthal and people like what they are used to.
