TC beyond Ni200: Nickel Purity, Dicodes; Ti, SS, Resistherm NiFe30; Coefficient of Resistance

[Trexwyo]

vaping with mixed wires is not TC vaping, it's power only vaping. You may think you are in TC but you are not, so why bother.

Look at the attached chart and try to convince me and everyone else that I do not have full temperature control. This is the results from a Tiger Coil made up from 28 gauge Ni200 wrapped with .8x.1mm Kanthal ribbon wire. Graph is from Device monitor by Evolv on a Reuleaux DNA200 Mod. Is the temperature perfectly accurate? Probably not, it's close and it is 100% repeatable. The Window width represents a time of 10 seconds

I will try

Atty:
You need an atty with reliable connection. I am not aware of atties notoriously useless for TC but bear in mind that TC relies on resistance change and you don't want any loose/lousy components produce any of it but the wire itself.

It's been my experience that any atty that has an adjustable 510 positive center screw may result in a atty that works poorly under temperature control. This hold more true when working with lower TCR wires such as Ti and SS

Isn't most tanks, the 510 feeds directly underneath? In your opinion, what is the best tank for tc?

For me, out of the three tanks I own, I notice the le magister (replica) performs the best. The worst is the kayfun v4 (replica), all thanks to the conductive spring beneath the deck. Silly design by a good brand IMHO.

Aromamizer by far (with the velocity deck).

Yep, love my Aromamizer for higher wattage (50-80w) tc. For lower wattage (25-40w) tc the STmini w/rba fits the bill just right.

Wth! I have that, how do you make the thing leak free? May I know your coil build etc.

Not going to happen imo. Aromamizers fall into the catagory of "Can't be layed on it's side" attys. Mine never leaks if kept upright.

I can however get it to the point of almost not leaking or leaking very little if I pack a lot of wicking directly over or into the four juice holes. Unfortunately that restricts juice flow to the point that I can only vape it consistently at 40w. At that point I might as well be vaping my STminis that never leak no matter which way I orientate them.

The Aromamizer does produce a more flavorful vape so I tolerate the inconvenience.

So kanger is coming out with some new mods and it says it does tc using nichrome. Anyone know the tcr for that?

 

[pbanj]

Also anyone happen to know what grade this is Round Jewelry Grade Stainless Steel Wire - Premium - You Pick Gauge 14, 16, 18, 20, 22, 24, 26, 28, 30, 32 - 100% Guarantee

For me the Kanger STM for single coil real 26awg. It fits so well never a problem capturing under the screws. Very little static resistance. with the UNK wire very easy to build and fairly cheap. I' need to find a true 26awg that is shiny. CW is a little thinner and is a hassle to capture at times. Maybe Stealth Vapes. Wish the Bloke was here so I would know if Stealths is a true 26.

I don't think this could work. The TCR for NiCR80 is around 0.0001/K, i.e. the resistance increases by 1% per 100ºC. For a 1Ω coil (at 20ºC), the resistance would be 1.02Ω at 220ºC. This is an increase of 0.001Ω = 1mΩ per 10ºC. That would also be the required accuracy for a TC to work good enough. Any error in measurement, static resistance change, etc of 1mΩ or more would be recognizable.

Only thing I could find on it said .0004 and even that seems too low to do tc with

 

[notarobot]

OK, not sure... I took the .0001/K (1%/100ºC) from here and here.

A TCR of .0004 would be still very low (around 40% of SS 304). However, that could work (more or less)... If that TCR would be correct, even a mod with SS mode should do the trick by setting the temperature to 100ºC, which would correspond to 220ºC real temp.

Cigatron, I only see leaking out of air slots in my STM's with RBA V2's, when my juice level is at or below the RBA's side juice feed holes. Some speculate it's a tank air pressure change. Have you ever experienced this?

 

[2legsshrt]

You know I was watching the Busardo video on XCube but he was saying he liked the Hurricane better then the KF V4 for him that is pretty amazing he is such a KF fanboy.

It is indeed a pressure change, from a vacuum to atmospheric pressure. The V1 rba does not suffer from that problem because the juice holes/channels are lower and are not exposed to atmospheric pressure until the tank is very very near empty. By then the wick can absorb most of what would have leaked out.

Well after Busardo said the Hurricane I think V3 was so good I looked it up and damn its $180 way too much for me.

I tried the Hurricane and somehow never made it work for me. Recently I picked up an Aqua FX and I'm very impressed with that. It's the only other tank that competes in flavor with the Ubertoot for me which is my favorite. It also is built in such a way that makes the device resistance rock solid so it works extremely well in temp limited mode.

The build is unconventional but easy to do after a couple of practice builds. I know the build method turns some folks off as it did me until I actually did it. The only thing that's critical is to use some gloves to wrap the cotton around the coil/ceramic to avoid oil from the hands contaminating the cotton.

The way the Aqua FX air control works one can manipulate the pressure in the tank during filling so there is no leakage with top filling which is rare in my experience for top filling attys.

The best thing about the atty (other than the great vape it delivers) is that it's cheap. There are two versions advertised for sale and as best I can tell they are identical and no doubt come from the same factory. One is approximately $40 and the other is approximately $20.

The Aqua FX looks pretty interesting. Try an Aromamizer w/ the Velocity Deck yet?

I haven't tried Aromamizer since it seems to be pretty much built for dual coils. I usually prefer single coils so I haven't given it a shot. On the other hand I break my own rules pretty often so I have a Russian V 3 coming. I think that is dual coil only air flow also. If I don't like it I'll probably sell it since the Russians seem to have a strong following and this one looks well designed.
