Titanium wire, vaping and safety

[AndriaD]

Yeah. 185C in Ni mode beats 240C in Ti mode.

I also use 185C on the dna 40 for Ti coils and it works great.

That's for 75VG juices. For 50/50 juices, I take off 5-10C as the boiling point is lower and it gets to hot for my taste.

Hmmm... I have no idea what C translates to, in F -- nor even how to get it to use F rather than C; guess I need to keep reading the little manual -- it does tell you how to switch to fahrenheit mode, doesn't it?

I use 85P/15V which is very different from any of the ratios you mentioned. But C means really nothing at all to me, other 0=freeze, 100=boil.

Andria

ETA: looking thru the English-language portion of the manual, I don't see any instructions for switching to fahrenheit... how does one do that?

185C is about 365F, Andria. The easy way is just Google "centigrade to Fahrenheit" and use an online converter. In the end, it will be adjust to taste because if you're mod has a curve for nickel it won't really equate to titanium and if it doe have a titanium curve they don't seem to be very accurate either. Either way, start out low and adjust up to taste.

I'm panicking... there's NO WAY to make it use F instead of C? Because if I have to use some online converter everytime I want to adjust the temp... well I'd be selling it.

Andria, you don't need to convert every time, just adjust ten degrees, up or down, at a time until you find what you like. Trust me it ain't rocket science, more like trial and error. Use the converter to get a baseline, and you already have that...185C=365F.

I use 260-280f Andria on the M class in nickel mode with Ti

That will work out roughly 125-138c

125c will make a good starting point if the Evic has similar software to the M class

I read those using the dna40 use temps a lot higher but that seems to be a one off compared to others

Andria

It uses F and C

You only need to scroll through F and it will jump to C and vice versa.

I can only think properly in C so that's what I gave you.

You can convert my numbers through Google into F and use those F with your evic VT.

The device supports both

Yeah, I can't think in C because I don't understand it; I've used F for 54 yrs now, so that's what I know. At least I can make it switch to F. I had planned on starting out with a coil about .5Ω at 350 degrees, to see how I like it, if the coil needs to be different resistance, or the temp higher. So, if use nickel instead of Ti mode, it should be a lower temp? Maybe 300-ish?

Tracking is showing me that the ti1 wire has reached Atlanta, so it should be here tomorrow.

I'm waiting to see a report on the DNA200. It comes with "custom: as a wire choice and the default just happens to be the TC curve from SteamEngine. Wonder how well it actually tracks.

The default at "Custom" is not the same as SteamEngine's curve. Over on the right of the EScribe screen, you'll see Load CSV, Save CSV, and Special. If you click Special, then select the only option Temperature Coefficient of Resistance (Approximation)... it defaults to 0.006. Ti Grade 1 is supposed to be 0.0035 and if you input that, it matches up to SteamEngine.

Default Custom: (-100, 0.6) | (0, 0.8) | (70, 1) | (200, 1.3) | (400, 1.9) | (600, 2.8) | (800, 3.5)
SteamEngine : (-100, 0.7) | (0, 0.9) | (70, 1) | (200, 1.3) | (400, 1.6) | (600, 2) | (800, 2.4)
Input 0.0035 : (-100, 0.7) | | (68, 1) | | (800, 2.4)

The input option doesn't show all the indicators, but the scale is 99% the same.

 

[awsum140]

Thanks, I hadn't looked at all the points and just noticed it "seemed" the same in default.

So how does it work in the DNA200?

 

[tchavei]

I'll let you know in two weeks

I didn't realize there was a difference between the Evolv .csv curve for Ti and the Steam Engine curve until you mentioned it but I just did some comparisons which I found interesting.

The indicated temperatures during a vape puff are quite different between when the default and Steam Engine .csv are entered.

It appears that whatever internal calculations are being done are being confused by one value at 800F which is clearly way too high compared to reality. I get much more accurate coil temps with the Steam Engine curve than the Evolv default.

It appears that the 800F value in the Evolv .csv curve is the slope of the Temp-Resistance curve rather than the resistance value at 800F (which it should be).

Interesting. So better to load the steam engine values?

I wonder why you have to input coil resistance as I can't see any practical difference in the generated output values?

I sent an email to Stealthvape asking if they could ask their Ti supplier to provide a TCR value for that Ti wire.

I doubt they have that data but it doesn't hurt asking right?

So how does it work in the DNA200?

While I currently have the Opus set to 520/530 to get similar vape at 380 in Ni mode, it seems more stable than the SXmini Ti test firmware. As the SXmini is what the wife is using, I've not had a lot of time to test it out. Initially for her, it took 500 in Ti mode to get to where it seemed the same as 360 in Ni mode and I left it with her to vape. The next day, the complaints started coming in that it wasn't smoking right so I played around with it for a couple of days going up/down in temp/joules but she still didn't like it, so I just changed it back to Ni and she's been happy ever since. It's strange though as some on ECF haven't had issues while others have.

So, while the DNA200 needs to be set higher than what I thought it would, it's been solid at those settings. While I'm using an 80vg juice, even at 530 I'd only consider the vape barely warm for the normal 2-3 second hits I take. I've got the preheat currently at 45w, punch at 5.5, and watts at 21. It hits 520 and the watts stay fairly steady at 18-19 to hold the temp.

The device inputs the coil resistance from it's initial cold coil measurement. I didn't do it....I'm innocent. (of that)

Seems like the Steam Engine curve makes the numbers look more sensible. The vape doesn't seem to change much if any at all. (as far as my partially dead tongue can tell).

If Stealth Vape doesn't come back with 0.0035 as the slope of a nearly linear curve they are going to give us something to talk about for the next month or two.

I'm not into Titanium but read a bit here.... FYI Evolv has not set a Ti TCR in the DNA200.... the curve shown as "Custom" is just for reference and they link Steam Engine in the graph shown in "Custom" wire in EScribe (click on "Custom Materials").... Evolv and others, as you know, have been working with Steam Engine.... just wanted to point this out so miss-information is corrected....

 

[tchavei]

To be fair, I couldn't find any mention of Ti in the escribe software.

The custom curve with the 3.5 value at 800F is shown in Profile 2 when someone selects "default" settings in Escribe I think. That's the reason I called it a default setting.

Correct. Ti is not mentioned. Profile 2 has data but no name. At first glance the data look like the Steam Engine data. so it's easy to assume that the data reflect that required for Titanium.
