ipv4 temp control question

[benearl1]

Hey everyone

Im wondering what the resistance limits are on the ipv4 for temp control mode. I've read .05-.1+ but I'm not sure how accurate this is. What I really want to know is if id be able to fire a dual coil 26 gauge ni200 build with it? Or should I get 28 gauge instead?

I normally use dual 22 gauge kanthol coils and would prefer to try temp control with the thickest wire for a dual nickel coil build.

length = overall resistance per gauge thickness

Simply make your wraps correctly for the required Min./Max.

Standard Resistance: 0.1-3.0 Ohms

Joules Resistance: 0.12-1.0 Ohms

* NOTE - the Thicker the wire, the more power used to heat said wire and the slower the cooling time.

So I have to build above .12 ohms to fire a nickel build on the ipv4? Can't dna40s fire .1?

You do realize you are talking Hundredths, right? Unless you have a VERY Expensive Meter, your not going to Nail any setups that Low.

*** That .02 is irreverent - You are talking about using Temp control and have 100w to work with.
Remember - Regulated Mod - NO Voltage Drop

Yea I know. I think I'm just not ready to bump up to a pretty thin gauge wire as I'm so used to how sturdy 22 gauge is.

I really just wanted to know if something like 26 gauge nickel wire would be doable for a dual coil... in an rda like the dark horse.

Should not be an issue. Calculate and build each at .3ohms or above and enjoy.
If you can find 24ga. you might prefer that.

Gauge thickness should not be a bother. Once built it is a stationary item anyway and Strength is irrelevant.

I think 24 gauge might be a stretch. Maybe a single coil if your lucky.. nickel wire is non resistance so it takes a lot of wire and wraps to get up to the requirements. It would be hard to fit such long coils in an rda.

That's why I was hoping to see if anyone was able to fit dual 26 gauge nickel wires In an rda and be able to get a .12 ohm reading.

just take your wire say 2/3 strands instead of one and twist it in a drill then wrap your coil.

i have experimented with many different builds w/my DNA40's lower resistance does not mean better, have discovered that a single coil between .23 to .28 gives a much better vape.....and you can get these resistances twisting strands in your drill.


edit: rite now i'm using a single .29 coil on my IPV4 and it's rockin

Should be no problem firing it as long as it doesn't go below .1 ohms or above 3.0 ohms.

Nickel builds below .12 work fine on the IPV4. This particular build shows as .078 on the SX Mini M Class. I think the limit is .05, at least the first build I tried was below that IIRC and it would not fire.

My other nickel build shows around .2. But every build I do on the Lemo comes out way lower than the ones I do on the Lemo 2, even with the same amount of wraps. This is 8 wraps of 26ga Ni200, BTW.

Huh, pic won't post. It shows .08 on the IPV4 display.

I have fired .06 nickle builds on the ipv4 although i prefer the builds a bit closer to .12 ish anyway for TC. But it will fire down to .06 for certain.

I have a twisted 28g ni200 single coil, it's at .06 and is great. Was having a hard time getting dual coils to reach a high enough ohm to use, was getting "resistance too low" alot so I gave in and went single coil. BUT- with the twisted 28g, .06 build,I'm only at 35 joules and °350. Thats alot lower than alot of people I've seen,which are maxing their mod out at 50 joules at °450-°500. Cotton burns at around °410 (I've read) so I'm liking being down at °350.
I was SURE I wanted a dual coil setup,and gave it about an hour of tinkering with different wraps, spaced not spaced,etc. Finally went single coil and I'm SUPER happy. Oh and by twisting the wire,it made it MUCH easier to work with,and I can really cramp down on the leads,they don't break as easily. Hope this helps, it took me a week or two t figure this out lol.
