I've been using vaporshark dna40s almost exclusively since the release.
In kanthal mode any mod can give you a dry hit. That's more an issue with the atimizer, build, juice and how you vape.
All I can say is set at 400 with the same atomizer, build, juice, and how I vape, I'm not getting dry hits on the VS like I do the iStick. I know it's designed to work with nickel and won't sense the temperature with the kanthal but it is different or I'm perceiving it as different :)

You must be perceiving it or something else is going on. Temp limiting doesn't work with kanthal. You can set it, but if you look the output should be in volts not degrees.

Remember that the resistance changes with heat in tc mode. So it might be 30a cold but it is going to change very quickly as the coil heats up. I don't know exact amounts but I know it is not just a few .0x it is .x

Except, you know, TC builds are, sorta, like, um, well, sub-ohm. Still a respectable amp draw, can exceed 30a on the SX350J if you build as low as 0.05 and push all 50j through it.

That said, the way we vape on a regulated box is really a pulse, not continuous, when you consider the applications these batteries were designed for and how they define pulse. 30-90 seconds falls in the pulse range.

From the ariticle: The likelihood is that in the new Evolv temperature-protected mods the wire poses much less of a hazard as it will not oxidise as quickly or be pushed to ignition temperature

After reading that article and information I don't think I will be trying Ti anytime soon. But to each his or her own.

I have tried 28 Gauge Grade 1 titanium on my DNA 40 and at lower temps it does work pretty well but I definitely wasn't getting the same flavor as I'm getting from the NI200. Plus it seems to make the juice heat up strangely and crackle more than the NI200! I have yet to try it on the SX Mini but from what I've heard it seems like the DNA40 is more suited to TI.

I just can't do the titanium thing, I'll let others play with that particular metal :)

Titanium wires for vaping

I started a thread on Ti and safety so take a look maybe. The stuff mentioned in this link is largely BS as it is almost certain that the wrong grade of Ti wire was being used. Ti wire is coated with a thin layer of TiO2 which is what makes it chemically inert. If you dry burn all to h3ll it will end up with a crust of further oxidation. With sensible use, I doubt it any more toxic/dnagerous than Ni (Ni oxide is far more toxic than TiO2 btw..).

Anyway its an individual choice. Works great for me. I have done a lot of research on this and I am happy the risks are no greater than using Ni (and probably Kanthal for that matter)!

Kinda confused here... I tried a twisted 30AWG Ni200 build on my dark horse.

dual coils, 8 spaced wraps for each coil, all posts firmly attached. Steam Engine predicted .11 Ohms. I read .08 on my meter.

SXmini reads it at .056... Hmm

I've checked for shorts, and don't see anything that sticks out like a sore thumb.

Any ideas? I know we're working with super low ohms here, but is that kind of discrepancy between the estimated value, the metered value, and what the device reads usually this far off?

I'll try again with just 30AWG and try to wrap it around the heads of the post screws rather than through the post holes. I don't think it would survive getting clamped into the post holes of the dark horse without some reinforcement, they're pretty massive

Right behind you...
What ID are you using? 8 wraps in a dual 30ga setup should put you around 0.07-0.08-ish, just like your meter showed you, so methinks you read Steam Engine wrong, or input the wrong values.

Did you actually try firing it? Sure sounds like a short on one of the coils to me.

As for the post holes, one trick is to use a piece of Kanthal in there with the Ni200 legs.

EDIT: Missed the "twisted" part. With twisted 30ga, you're going to ohm out closer to 27-28ga, so guess what? 0.05ish. Yihi does not speak with forked tongue.

May be you forgot to click Dual Coils under set up.

I ran these numbers:
Nickel 200 round,twisted/parallel
Twist pitch 1.0mm
Number of strands 2
Dia. of wire 30AWG
Set up Dual Coil
Target resistance 0.056
Inner Dia. of coil 3mm
and got 8.34 wraps.

It's a 3mm ID... Sorry, forgot to mention that

Just figured out where I was messing it all up... I had Steam Engine set up for a twisted SINGLE coil, instead of dual coils...

I took out one coil, and BAM I'm right at .11 ohms, which is what I was aiming for. So steam engine was right on the money. It was me that was all jacked up :) No shorts in the coil, just a short in my brain

And yes, I did fire it... LoL, as dangerous as it seemed, I was pretty certain the battery could handle it (LG HE4), so I wanted to see if it really could fire a coil that low. It actually worked great. The SXmini got pretty warm, as can be expected, but it worked like a champ.
