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

[TheotherSteveS]

Hi Steve,

I'm using a couple brands atm. I really like the Lightning Vapes 28ss, 36ss(ga) a friend sent me to try. I'm also using MKWS (26, 32 and 28, 32ga) Clapton wire I bought from fasttech. I like them both but the 28ss,36ss LV wire is easier on the batteries
Clapton Wire
$3.69 Authentic MKWS 316L Stainless Steel Resistance Wire for RBA Atomizers - 28/32 AWG / 0.3mm/0.2mm dia. / 9.5ohm / 5m(15ft) at FastTech - Worldwide Free Shipping

Cheers,
Steve

hi Steve,

thanks for that. I will check it out!!

Best

Steve

Sadly, "TheBloke" has not logged on to ECF for quite some time so it is rather doubtful that he'll be providing any 'evidence based reference'.

Sadly Tom bowed out a good while ago and has been out of contact since. Hope he is ok but i fear we won't see him back here

 

[cigatron]

A real bummer. He authored many great posts.

I'd like to think that many of us ventured into the unknowns of exotic wires because of his posts. I surely did not know "TCR" from any other TLA before I discovered this thread. His research into suitable TC vaping wire beyond Ni and Ti is how myself and I'm sure many others discovered NiFe.

Whatever he is up to these days I hope all is well for him.

 

[Mactavish]

Indeed, gone but NOT FORGOTTEN! I've copied and saved many of his posts!

Yesterday on my Kayfun 5 clone that has the twisted 28 gauge SS430 from Unkamen and SE's 430 curve I closed off the juice control and vaped it dry. It worked as expected, ended up no vapor.
This morning I did the same with my other Kayfun 5 clone that has a coil of Crazywire's 25 gauge SS430 and a using a TCR of 0.238. Same results, no burnt taste just no taste, no vapor (well next to no vapor).My live view of the end.

This is for Crazywires 430 ^^^

You're having problems because you're not using SS430. I bought once from crazywire. Emailed them and told them that they must have sent me the wrong thing. Resent me wire but got the same stuff. Using it with the appropriate TCR or curve you get no vaporisation; you need much higher values. This is definitely not SS430.

Sorry but I'm not having any problems with it, you must have me confused with someone else.
The SS430 from Crazywire listed composition matches up pretty well with AK Steels data sheet.
Maybe it's Unkamen's that not the real 430...LOL

Got an SXmini Q class a few days ago. Anyone been playing with the sx450j?

There is 1-2 dedicated SXminiQ class threads.....

I have a RED one. Seems ok. It works.

Been on the thread. Assuming your preference is the dna200 from your comment. Mine is.

I own two DNA75 devices. Besides their inbuilt limitations I don't like them any more or less than my other devices. (actually quite a bit less) I don't own any other DNA devices.

The point I was making is that I find that mostly ALL brands (excepting Sigelei) can/will produce a decent TC vape.

Vape wise the "Q" does not bring much of anything different than a Boxer 350J. I consider DNA devices "unfinished products" as a Winderz computer and some amount of Websites need to be sought for profiles, settings and such.

The YiHi chips (and even the Wismec) will power a wider assortment of builds than the DNA75.

Actually my current favorite setup is nether YiHi or DNA powered.

Wismec Pressa TC100.

I have so much wire that I just ended up shelving the CW SS430. After the Firmware update my SS316L Clapton wire is working great. If I want SS430, I'm just using the Unkamen

Yeah, well, unfortunately I have 200M of the stuff. My wife likes the way it coils because it is not springy. Unless CW decides to replace it with NiFe52 or some 316L, I'll be using it. How can I go against the Head Coil Twirler & Wicker?

@dwcraig1, @jazzvaper do you or anyone else have any NiFe30 from zivipf? I've got some but am having trouble getting it to work right in TC. the only mod I have to run it on has a sxj v1 chip. Others only dna40. Running a single coil 6 wraps 3mm Id comes out to .11 ohms. Using 0.00525 as TCR. set at22j and 500f. Coil hits 500f almost immediately when fired even though wick is saturated. I am also using a contact coil that I dry burned. I've redone the coil. A few times the exact way on 2 different atties, so as far as that goes there isn't an issue unless I'm setting up incorrectly(contact, dry burning). Anyone have any suggestions?? Also, can u use this wire in watt mode as well?

I've always got better results in TC using spaced coils. I have some NiFe70 from Crazy Wire and I'm using their recommended TCR of .005 and it's working fine. I'd give spaced coils a go if it was me.

 

[dwcraig1]

Yep, same TCR
I did contact coils with it and used Steamengines curve for alloy 120....it worked as it should. I didn't really care for it's lower resistance but that wasn't any problem

 

[GeorgeS]

Greetings, it sounds like you have 26AWG wire. (based on ID and resulting resistance)

Contact coils need to be pulse dry burned to ensure that an oxide coating is formed to insulate the coils from shorting out. Carefully ensure that the coil is heating inside out without hot/cold spots.

Other than the above I'm unsure what TCR values a SXK V1 chip accepts and I'll generally start with 200F and slowly work my way up with a new wire/coil/setup.

While TC wire ought to be used in TC mode only with care older mods with an actual VV mode can be used. VW mode should NOT be used.

Finally got a dna75 and trying zivipf NiFe30 again. Dual coils, 26g, 7 wraps each, .15ohms which is what SE predicted. Coils are contact & dry burned. Loaded SE profile for nife70(alloy 120) & nife48(alloy 52) as well. Selected the alloy 120 profile. 35 w & 450 degrees. When I am firing the atty it will work as expected but I can put the mod down & pick up a few minutes later & Fire & the profile on screen has switched to watts mode. Meaning it still has my nife30 profile name at the bottom but the degrees have been replaced by % Example of screen on the left.
0.15ohm. Vs 0.15ohm
450f. 85%
Nife3. Nife3

Any idea why this is happening?
I assume this is battery %.

 

[dwcraig1]

You very well might not be getting the coil hot enough quick enough. Sorry but I forgot just what the numbers are. Try increasing the power and see if it functions then.
And if it does either use a single coil or smaller gauge wire for duals with that wire.
Sorry but I'm kind of guessing here.

Jumping out of TC to power mode on a dna device has only happened to me a few times. Haven't tried nife 70 but one time it was a loose 510 screw and once a loose post screw. A juicy 510 connection on the mod can cause it too.

For whatever reason your dna is not seeing the coil res rise at the rate predicted by the .csv file. Even though your mod displays "nife 3" check your material type in that profile and the tfr's for that material ie make sure the correct .csv file from SE is being used for that material and that you've chosen the correct material for that profile.

Just for fun check the preheat setting in Escribe. The default may be too high for your build. That would explain your device instantaneously reaching temp protection even with a saturated wick. If you're tootle puffing at 35w try a preheat of 50w.

As with others here I typically run spaced coils for tc. The exception is with twisted and claptons.

Yes, the % is indicating battery capacity based on your settings in the display screen tab for power mode.

 

[GeorgeS]

Humm... I must of missed something here.
Coil wrapping

A dual coil NiFe70 (Alloy120) 26AWG, 2.5ID needs 18 wraps per coil to hit the target resistance of 0.15ohms.
