Uwell Crown Temp Control HELP

[Clydde26]

Everything that I have read suggests that they do have nickel leads... I have rebuilt a few and I have noticed that the leads are arc welded...the coil itself is a parallel coil... so I never really investigated it just assumed it was their way of connecting the two parallel wires without having to twist them... Obviously my assumption was wrong. With that being said I cant give you a definitive on whether it messes with the readings or not.... I know that on my RX200 i hit temp protect extremely quickly with the .25 coils. I havent used the .5 coils. But I can get a satisfying vape on SS TC mode at 600 degrees @70 watts with 7-8 sec pulls and no burnt/dry hits. That in my opinion means it works. Now is the coil really running at 600 degrees doubtful because the cotton would probably burn....but it is how I have mine dialed in and what works for me. The Evic mini uses the same TCR for SS as the RX200 so we would be in the same boat. Now if you would like to tweak a custom TCR and then dial down your temp to lower than 600 degrees... you can set you TCR at 0115 and get a satisfying vape at 475-500 degrees. Its all your preference and how you like to vape. Thats why TC is a different monster all in itself.... but as I have said more than once.... Yes in a perfect world and too all the sciency people out there if I set my mod to 475 I want it to consistently vape at 475. Too many different chip sets out there for that to be even remotely possible. So the ultimate goal of TC is to get a satisfying vape while limiting dry/burnt hits. In TC i can take 10 sec pulls and not have fear that I will get a hot pair of lungs full of cotton smoke towards the end of my inhale...that piece of mind alone is why I use it.... I dont care if the coil is running exactly at 450 degrees... I care that my vape is @ a preferred temp and flavor for me and that I wont get the burnt hit. It allows you to take longer draws with less penalty. You cant do that in wattage mode no matter what.

So now your going back on your original statement and saying AFAYK Uwell isnt advocating using their regular SS coils for TC mode not that of AFAYK they arent capable of being used in TC mode?

Was AFK, not ignoring you. Communication breakdown happening here.
I know that you can use SS wire for TC, if your mod supports it (mine do, RX200 and Cuboid with TCR modes).
What's not clear is if the SS Uwell coils are specifically made for TC use, and all the evidence says that they're not being sold as such. Just the .15Ω Ni coil is. That's what I was asking for: some proof that Uwell or another source is saying, explicitly, that the standard SS coils can be used in TC mode.
You obviously are doing so, which is totally fine and cool.

The Uwell Crown came out well before SS temp mode was even a thing other than Dna devices. So why would they market them that way is all I am asking. It is their standard coil much like kanthal coils are kanger's standard coil. So why would you limit your market by saying my SS coil is for Temp control. Then you are limiting your market field way down. Have they come back and updated it saying they can be used in Temp Control mode...no they havent done that either but you have to think they have been working on the Rafale Which they were hoping would be the crown killer as well as the chinese holiday.

Maybe for some's peace of mind having it labeled as TC compatible from the company justifies it....but it doesnt make it more or less of an option if people are doing it.

So yet again im confused on why having a company saying it can be...makes it more truthful than those out there that are. If it is being done then that is a pretty big "can be" in my book regardless of a companies stamp of approval.

Sony VTC 5's were never meant to be placed in vaping devices. They even went as far as releasing a memo stating the fact. People still "did" and they turned out to be some of the best batteries to use in higher powered vaping devices.

Let's just wrap this up with:
You can use the standard SS coils in TC mode if your mod supports it, and that it may take some fiddling to get the vape "just right" - but it's do-able.

Fair enough?

Hey I am all about compromises my man... people may view this as a argument or battle....but honestly it was very informative for me too... I had to do a lot of research on the fly just to make sure that i wasnt being absurd. Like i said earlier I had no idea the leads were nickel until i dug deeper into 4 different forums.

So are they doing a NR-R-NR setup with the nickel leads, or a nickel/stainless wrap?

 

[Clydde26]

its a nickel lead then it is a tri arc weld.... so imagine a dual parallel coil and then a nickel lead...where all three wires meet at the intersection they arc weld it. Something like this

Arc Weld Dual SS Arc Weld
NI200 -----x============x-------Ni200

The arc weld fuses all 3 points on the wire together at one point.

 

[Douggro]

Got it.

 

[Clydde26]

I mimick the arc weld when i rebuild the crown heads but just use a drill to twist it. I dont use nickel leads obviously either.... but like i said in an earlier post i just thought it was a weld to keep the wires together so they didnt have to twist...but apparently it is also to add the nickel lead.

Given the low resistance of Ni200, it's effectively a NR-R-NR coil then..

 

[inspects]

Personally I haven't read anywhere Crown uses Nickel leads to their SS coils, does anyone have a link to Crown literature regarding this?...Meaning not forum posts.

 

[Clydde26]

It is mainly in forums that had DNA devices that stated it...but I also found a pretty reputable Youtuber who quoted the same thing.

 

[inspects]

You would think Crown would say there is Nickel in the coil leads if in fact there was, we all no you don't want to dry hit Nickel.

I've never had a dry hit using any of their coils since the inception, therefore I haven't tried temperature control. I may try it for the hell of it soon. But I haven't used the 15 nickel yet.

That is exactly correct.

Well as Doug pointed out its a Non-Resistance-Resistance-Non-Resistance setup The power is strictly traveling through the leads themselves and then powering the coil... The portions that are nickel are only there as a conductor. Now the tank heat may heat the leads a little bit...but nothing that would set off anyone who had irritations to nickel.

I haven't dissected one of the coils yet to find out, but I'd dare guess that you'd have to run it pretty hard to get to the Ni section of the wire and start burning it.

 

[inspects]

I have several dozen used coils, I'll rip one apart to see how they're made.

 

[Clydde26]

Ive rebuilt the head and the wire i pulled out was roughly like my diagram.... 4.5mm dual parallel build with two arc welds just before the leads.

 

[inspects]

They certainly make damn good coils, I have never burnt a coil since the atty's first came to fruition. After a few weeks I change the coil for better taste...but I don't run them at 100 watts either...50 is usually the max, which suites me fine for my vaping needs.

 

[Clydde26]

Yea i wish i had known how to break them in correctly... I read a review of the tank on vaping360 and he said the best vape he got was at 85-90 watts.... so when i got mine i vaped it at 85-90 watts right out of the package...probably lasted me 4 hours each.... I was very disappointed.... and then as I started educating myself more I realized that stainless has a break in period that has to be reached before it can sustain being vaped at such high wattages.
