Temperature Controlled wire

[Spender1786]

I am fairly new to the vaping scene, and i am just about to buy a VS rdna 40. As i have read on here, you cant use kanthal for TP mode.....but why. I am only asking because i am interested. I believe you have to use NI200, again why. Can you use any other wire for TP, other than NI200

Stupid questions maybe....just thought id ask.

Here is a basic tutorial from Evolv's web site...

I was more after a technical reason why you cant use kanthal and why you must use Ni200

 

[dr g]

Ni200 has a higher temperature coefficient of resistance, which is how temperature monitoring works. Also the formula of Ni200 is over 99% standardized while there are several percent potential variance in kanthal, adding inaccuracy.

Thank you Dr g, thats what I was after. Can you also use Ti

yes you can. the temperature reading will be off, but it will work.

where can this TI wire be found, please & thank you?

will this work ?
25' roll - 30ga - Grade 1 CP Titanium, Wire Dia.: 0.016"

somebody has to know if this wire will work, talk to me!

This works well Titanium Laser-Weight Round Wire, 30-Ga., Soft
But you have to reduce your temperature control by 80-100F

here is what i wound up getting, gonna twist 2 or 3 strands on a drill then coil-up, bought 2 rolls.
25' roll - 30ga - Grade 1 CP Titanium
Wire Dia.: 0.016"

it's listed about 3/4 down the page

Great price makes it worth it to try, the other roll is 200 feet, how much was shipping?

 

[sando7]

3 bucks and change




rite now i'm using NI200 dual coil 28ga at 10 wraps each and it's coming out @ 0.10, hitting it at 27.5 watts with TC set at 440.

getting a pretty good vape.

 

[BobC]

Very cool, thanks

after a couple of days i have found 2 good TI builds that seem to do well for me.

took about a three foot piece of grade#1, 30ga TI & folded it in half and spun it pretty tight in my drill, this was way more than enough for a few builds.

conclusion, (single coil) 5 wraps on a 3/32 bit squeezed together as tight as i could get it without touching came out @ 0.20 exactly and held, 4 wraps came out @ 0.17. , temp set at 370-380 degrees on both and between 23 & 27 watts wicked w/Rayon, and they both chucked the Vapor.

what i really liked is you can use any dripper you want with post holes big enough & able to crank it down without breaking the wire.
i'm using a clone DNA40 so your mileage my vary on other devices,

Great info here guys, so titanium wire works like nickel, just set -100 degrees lower (320 titanium would be like 420 nickel)

 

[sando7]

yes basically, you will have to play around with it until you find your sweet-spot (80 to 100 degrees lower), also the TI wire builds last alot longer than NI200 and is more forgiving and the legs do not snap so easily......the NI builds get hot and come loose i was going thru 2 NI coils a day and the TI build i'm using now has been in service for at least a week and holding resistance....just make sure you buy grade#1 TI.....24 grade is what most prefer but it's hard to find so i settled for 30ga i just double a piece and twist it in my drill......presently using a 7wrap single coil that came out @ .24 and it chucks the vapor and you can build on any atty you want no hex screws needed...good luck.......there is a link to where i bought mine on page1, scroll down to the bottom of the page and it's reasonably priced.

Hey, guys. Just an old, lame guy, here.

The point is to get the maximum resistance spread over the temperature range of working atomizers. Nickel happens to meet that criteria better than titanium. The reason you want the highest resistance change to temperature, is to maximize the accuracy of using the resistance change to indicate temperature. Evolv researchers aren't stupid. They have a slightly bigger budget than us hobbyists. They made the very clever microcontroller program to cutoff power when the resistance of the atomizer approached the temperature limit set by the user. However, by knowing the preset temperature limit, they actually scaled up the amperage to the coil on approaching that limit, so that the time to reach vaping temperature is greatly reduced, knowing where the brakes to that ramp up must be applied.

Now that is smart. If I were younger (and less lame) I would apply for a job, there. This is the absolute future of vaping. Bank on it. No burning. Fast vaping. Careless vaping. It just doesn't get better.

I've tried both ni200 and titanium grade 1 wire, and while I agree temp control as a technology is pretty nifty. As a "experienced" vaper, I'm not impressed with the results. Every body Vapes differently. I like my vape on the warmer side, usually with kanthal around 1.5ohms somewhere between 15w-20w. That gives me the heat, vapor and flavor I like. Now maybe because I've vape basically the same kind of build for so long, I'm spoiled? I'm resisting change? I dunno. I'm not able to reproduce the heat or flavor on temp control builds. I've tried and tried... I get plenty of vapor but it's down right cold almost. No where near the temp I've come to expect when vaping.

I agree that the technology - especially for new vapers, will be amazing. Think about the learning curve we all went thru learning how to build, wick, etc. I've used silica, ekowool, cotton yarn, mesh, ss rope, cotton balls and now Japanese cotton (KGD). Everything except ceramics (that I'm aware of). So TC has its place, I personally just haven't found it to be a 100% replacement of kanthal builds.

Titanium is less responsive than nickel. You can apply an offset, but you will be wrong most of the time. What you really want is a metal that works for vaping. Use the actual response curve, and not the Ronald McDonald hamburgerler zip top.

Okay, sorry, I am trying to cancel that last post. It was just a rumination. Can I just erase it? I guess not. I guess i will have to be gone for another few years. Oh, well. Love you guys, take care.

I use Ni200 and Ti and 24ga Titanium on a 3mm bit 6 warps 0.24Ω rocks @ 15.5W 320°

The 24ga is easy to work with and even with spaced coils is small enough to fit in any atty I own. Refinement is almost non-existent on any of my mods. Don't get me wrong I like and use Ni200 but the TI is just more consistent for me and produces great flavor with very little hassles.
