Temperature control with kanthal

[Bobsbeer]

This post comes from my other one about high watt devices, and found this early review about the iJoy Asolo.  I'm not sure how good/reliable this reviewer is, but I do like the fact that the Asolo appears to work with kanthal. Remarkable if it does, but early days as they say. If it is reliable, it throws the door wide open for temp control.

Ive seen other reviews saying that for TC mods with purity setting you can set the purity down and use kanthal builds for TC? Don't know how true it is and im not saying try it but i have seen people saying it??

Can't be done with Kanthal without an extra sensor . Kanthal has been developed to be extremely stable at high temperature and I don't know why this keeps cropping up is it another ignorant reviewer or the manufacture? (I use ignorant for it's true meaning and not an insult, nobody knows everything)

And? Is the editor important?  I should add that Dewhurst's round our way are butchers, so that may be relevant.

This Ijoy asolo seems to implement another brand of temp control ive not seen before with its 4 button interface and control via manipulating a percentage value?

my very limited understanding is TC works with some wires/metals as the relationship between temp rise and resistance change is linear in some cases ie nickel and titanium. metals which dont have a linear temperature coefficient of resistance within similar scale boundries cant be used as successfully.

Now altering purity settings and in the case of this ijoy manipulating an arbitary percentage strike me as ways of increasing a variance rather than remapping the whole model to a new scale or curve, so the device is tricked into working rather than actually working as intended, a bit like avoiding car accidents by applying the handbrake all the time to ensure you cant drive off.

Without more information I'm not sure your analogy is correct. The fact that it works is more important to me than how they do it. A lot of people poo pood this mod from what I've read before it was released, for probably good reason, given the claims by some manufacturers in recent times. It seems to have been overshadowed by the Evolv DNA200 coming out at a similar time. What seems to be important here is the control of kanthal coils, which are everywhere and used by most atties. To me that is a game changer and puts Ni200 on the back foot.

It will not do temp limiting with Kanthal without a separate sensor in the universe with it's laws of physics, the Temperature Coefficient of Resistance (TCR) of Nickel is 300 times greater than Kanthal as it is so low being one of the design goals of kanthal.

If a mod had a 10 F sensitive with nickel it would have about a 3000 F sensitivity with Nichrome, but of an exaggeration as the resistance would be higher but Kanthal is going to be at lest three magnitudes less sensitive.

Temperature Coefficient of Resistance (higher is better for temp sensing):
Kanthal A1 0.00002
Nichrome   0.00004
Titanium    0.0035
Nickel       0.00641

I find nickel a lot easier to work with than Kanthal and would not like having to go back to Kanthal for some builds at all.

You may well be right, there doesn't seem to be any argument regarding the coefficient difference between Ni200 and Kanthal. While my opinion is based on the apparent results of one review, it does seem to work. How and in what way I don't know. I'm only going on what I see in one review. I don't have one, so don't have any first hand knowledge. That's what I'm asking. Apart from the review above, what evidence is there that this works, or more importantly doesn't? Let's face it, there were numerous reviews that said the Smok Xpro M80 worked, but we all know what happened with that one. Having said that first impressions are good, even though it may not be perfect.  This is from IJoy's site.

Does this mod come with its own atty, I think it can be done, if I joy can do it is another question.

[VapingBad]

OK Bobsbeer I watched the video and it is definitely not "temperature control" like the thread title says, barley even temperature limiting and only then if you stretch that term beyond all recognition. You can't set a temp at all, like the failed SMOK it attempts to prevent dry hits but still kills the wick and you would have had the nasty dry hit taste from that, in the video the wick had a burn that is consistent with well over 500 F on it! The guy was going through some steps to "let it learn the coil" so I would guess that it just takes the highest resistance it sees in that state then shuts down when it goes over that. I don't understand why they made this I can't see that it has any positive points just negative ones

I would stay well clear of that.

[Bobsbeer]

From what I can tell, it doesn't have a specific atty. At least I haven't seen one on the pictures.

[letsavit]

Bobsbeer a temp controlled atty running a kanthel build isn't that far fetched, a temp controlled kanthel coil is...look at the figures VapingBad posted, a chips got nothing to work with alone. Thier claim to control "all wire material" with no more information gives me doubts they can do temp control at all, think Smok claimed the same? And that was so. I would sit back save your money and wait for some more reviews mate...

sorry to diverge from the subject in hand but has the latest smock cube 160w been proven to have naff TC too???
or are the smock comments ment for th M80 Xpro?? cheers
