Kanthal & Ni200 for TC

[danjabu]

Is it possible to build a TC coil from kanthal and Ni200? I've read somewhere someone apparently did it with a K & Ni twist but I don't get how that would actually work... Or am I just being dumb?

Also, not one single coil I make for TC works at all haha. I've tried gauges from 22 to 30 Ni200 and also tried titanium still had no joy there. I'm most likely doing something wrong, like possibly ohms wise I think..., but I don't know what !!

Any help would be much appreciated!!

Thanks

it is possible to twist Ni200 with kanthal and many do! The idea is that kanthal provides some mechnical stability to the coil, as Ni200 is kind of soft. Because Ni200 has such a much lower resistivity, the kanthal doesnt figure in the equation as the current will follow the path of least resistance!
Doesnt sound like your problem will be solved by doing this though. To help we need a bit more info

what atty you using?
what mod?
what builds are you trying? Ni or Ti??

i will stay tuned!!!

Twisted messes and the 13heaven9hells atm, but I've tried with the dog and goblin as well :-/.

I will attempt one tomorrow and post a picture or two

With the following information, we might be able to diagnose the problem:

1. Description of the way(s) in which your builds don't work (doesn't fire, too cold, too hot, bad taste, low vapour, burning etc. etc.)
2. Coil information (material, gauge, number of wraps, spaced/contact, coil diameter, resistance)
3. Picture of your wicks (overwicking is a very common problem for TC builds)

 

[danjabu]

I know about over wicking so I've made them with increasingly loser cotton stuffing.

The coils have been 22/24/26/28/30 gauge Ni200 and med gauge titanium. I've tried between 6 and 14 wraps on single and dual coils, with spacing and without spacing (contact coils) I've also tried various different spacings and nothings sempt to have made a difference. Also tried from 1.5mm up to 3.5mm for in spacing.

The builds either do not register/register too low, or register high enough to fire but then dry burn and set alight my cotton even at 250/300℉.

I will attempt to post some pics here later when I'm home and show you what I've done and see if anyone can see where I am going wrong.

If the mod is underestimating temp, then my guess is it's either a calibration error or a static resistance problem.

Can you give full details specifically for one build that overheats - a pic won't help, I want to know if the resistance of your build is abnormally high compared to theoretical (this would support a static resistance problem causing overheating). I have this problem with my Kayfun 4 and cannot use it for TC, I'm thinking you might have something similar going on.

Did I miss what mod you're using? I know there's a few rouge evic mini's out there, I know, I'm stuck with one.

Right so I had another bash at this last night and again it failed :/.

I've tried this on my IPV 3 Li, DNA40 and my XCUBE 2 and not one of them has worked as it should

I tried a dual coil 6 wrap 22g Ni200 build, resistance was low and i mean really low, so re wrapped for 8 wraps a coil and it came out registering at 0.12ohms, set the coefficient 0.006, tried a spaced build, and nothing, just straight burns my cotton.

Tried again with the same build pinched, same result. Tried a 8 wrap spaced with 28g and resistance came out to 0.21, set the coefficient again to make sure it was correct, and again dry hit burnt cotton.

I really don't get what i'm doing wrong, i have tried raising the gauge to see if the thicker was the issue, i've even tried to a properly spaced coil and it's not making any difference.

Bit annoyed now as i've spent 20 quid on nickel, and i cannea use any of it! haha

8 wraps of 22 gauge ni200, dual coil and the resistance is 0.12. Did you wrap them around a drain pipe? Lol

I'm doing 2 x 10 2.5mm wraps with 30g NI200 to get a 0.1 dual coil build in a Zephyrus. If I try with 28g it's too low, but I think it's the coil spacing that causes the issue. If I do a very tight coil the resistance is always way too low as it's bridging. I don't dry burn NI coils either so it's harder to tell what's going on.

I can get down to 28g in the Bellus as it has the room and I have a good performing 3mm dual coil build in there at the moment.

Using 2.5mm coils with 30g in a TFV4 dual coil deck too.

danjabu are you changing the settings for your X Cube II on the device or using the app? When I first got mine the changes on the app didn't stick a few times so I do everything on the mod now. Latest firmware is a lot better with TC than the one it shipped with so worth upgrading if you haven't already.
