Cutoff is at 0.8 I believe- mine will fire at 0.8 anyway- I've read where people have for them to fire down at 0.7 but haven't had the chance to try mine that low. I try and stay between 0.9 and 1.1 dual coil

that's the difference between the v-1 & v-2's. the v-1's have a 1.2 shut off but the v-2's will fire as low as .8, but like bronze stated at .8 the max voltage is like 2.9v, at that voltage your only able to obtain like 10 watts so if your after a bit more power 1.2ish will give you the most from the provari.

There has been every conceivable kayfun build attempted and reported on this thread. I tried something a little different and want to chronicle it in this thread as a contribution to the vast knowledge gained and shared with my fellow Kayfunners past, current, and future.. I wanted to see how long I could make a coil last. To refresh, my coil is a 30ga, 10 wrap, 2.0mm (5/64ths) ID coil. I've used primarily silica wick but have also run cotton as well. I built this coil on December 1, 2013 and it is with great sadness that I announce I had to euthanize it tonight. There were two reasons. The primary reason was that it was no longer glowing from inside out as it had been to this point. The glow started on one side and worked its way to the other end. Efforts to re-crimp and repair went without reward. The second reason is I'm getting resistance creep. The coil started as a 2.0ohm coil and it is now worked its way up to 2.4ohms. I'm sure I could get continued use out of this coil, but decided to retire it to the stud farm because building a new coil is essentially effortless, inexpensive, and why settle for anything less than perfect?

Anyhow, thought you'd be interested. Very few people use a coil till the end of its useful life so I wanted to get it chronicled.

Triple twisted 32g 9/10 wrap coil, measured in at 1.6 ohms... Running at 4.5v.

I did an angled coil this time around and went with a S shaped cotton wick.

Massive flavour and vapour, although it almost seems to be begging for more power. A LOT MORE!

dusty I have and still do both orientations but imo I think the angled coil with the S- bend wick is slightly better and is my preferred coil for sure. maybe its in my mind but I feel like its a more saturated vape. as for the tri-twisted 32g, love it but don't use it with my 15watt regulated devices.

I tried cottons and it just didn't work for me. Silica is what works great for me. I keep trying 1,2,3 and 3.5mm silica and they all work. I'm currently using doubled 2mm silica and loving it. With 30g kanthal 5/6 wraps at 1.8Ω with 100% PG.
I believe that silica is easier to build and to get right. one really just has to wrap some kanthal around the silica and it works, if using silica it is not as crucial to get the proper tension around it compared to cotton. cotton is soft and is a bit more tricky to get the proper tension of the kanthal. if one has the kanthal too tight it just doesn't work that well, if its too loose, same thing. cotton expands, which also adds to the equation of proper amounts. either way though, both wicking materials really produce the same results so whatever works for you is the material one should use.

I do this to some extent, bearing in mind that I don't have a torch, I have a lighter; however, I'm a little bit leery of applying too much flame, because once I apparently applied so much that the wire just broke. Of course, that was 32ga, and I use 30ga with the KFL+, so maybe not as much of an issue. That 32ga is so fine, it gets brittle very quickly.

But since I do use 30ga with the kayfun, I may try a little more flame using the needle-nose to hold it *gently* while I flame it, and maybe not need to work so hard at compressing it after it's mounted.

I also informed my husband last night that what I *really* need are some ceramic-tipped tweezers, so I can hold it *while* I press the fire button; they're kinda pricey at $14-ish, but I'm thinking entirely worth it. Especially when I start working more with the 28ga I just got, because that wire is thick enough to be really stubborn, so pressure while firing would be really useful.

Thx!
Andria

actually andria I feel like the 28g is easier to work with compared to thinner wires. for me the thinner wires are much more springy. the thicker gauges seem to stay much better.

I've used both; I only switched because I was having problems learnin to wrap coils and someone at a b&m was cool enough to show me on one of
My kfls he wicked it with cotton and after I saw how easy it Was to thread compared to
Silica I was hooked- albeit if not wicked right and the cotton burns it tasted like used toilet paper.

that's why I use cotton myself, I just find it a lot easier. im always messing with builds, I probably have close to a hundred coils in a container that can snap onto my kayfun in a second. so I just snap on a coil and thread it with cotton. you simply cannot do that with silica as easily. to me it just seems like a micro coil & cotton has a lot more options.

    Sorry but Sterile Cotton is Sterile Cotton to my taste buds. I'll just stick with CVS or WalGreens. No waiting, and If it can be used when I cut myself (again), then it's good enough for me. :facepalm:
    Now if I can only get my darn arm to stop bleeding.:evil:

    Me too TNT , it's cheap and it works , don't fix what ain't broke .

    Thought I was the only one- got bored the other night and decided to start wrapping

    I simply don't understand the obsession with 28 guage. I wrap everything in 30 guage and depending on ID and size. Heck I can go from 0.3 up to over 2 ohms. Torch and wrap. But then I cheat and use a coil winder. (wish I had a pic of it). I got it off Ebay. Not to much cash. Oh heck I'll go find the darn thing. BRB.

    Just get the complete set. Comes with 1 mm, 1.5mm 3mm, and something huge. I used a wire coat hanger to get my 2mm, wraps. Easy as pie.

    Huh? I didn't know anyone wraps wire around cotton. Most people (myself included) make a coil, install it in the atomizer, and then wick it with cotton. When it gets a little funky, pull the old cotton out, dry-burn the empty coil, and put new cotton in it.

    The tricky part is getting the amount of cotton in the coil just right. This is where a consistent pad like a Koh Gen Do makes life easier than generic cotton balls do; I find it much easier cut strips that are always the same size and produce consistent wicks from such a pad than from any other form of cotton that I've tried.

    i have 4 kayfuns and honestly i have done just about every possible set up that i can think of, i just love messing with coils. the thing is that there is not that much difference in all those builds, some are slightly better but not a huge difference. a couple of weeks ago i installed what i believe to be the best set up in the kayfun, its a dual coil with a orientation perpendicular to the juice channels. this is a twisted 32g coil with a total resistance of .9Ω. i have this on my dna-20 mod and vaping it at 20 watts. although it is my favorite, if i vape it side by side with lets say a single micro on my provari the difference is just a little bit better. so i keep building to find something that is wayyy better. along with this set up i drilled out this kayfun to 5/64th's, there again a little better airflow but not that much of a difference.

    me either. the result of too much cotton is, what i stated is a tight coil. the result of not enough cotton would be a loose coil. yes trying a micro coil around cotton would be a great feet for sure.

    what atty do you do a .3Ω coil with 30g on?

    I haven't built as many different versions as you Diver, but I've built maybe ten different ones...gauge, wraps, ID's, silica, cotton, etc.. Truthfully, if there is a difference in performance I wasn't able to detect it.
    agreed for sure. the slight differences I see are mainly how different coil designs handle higher wattages. watt for watt I have found one coil design to be not that much different to another.

    To me, the biggest difference in coil design/performance are those used for subohming in a mech Vs using a 1.5 - 2.0 ohm in a regulated mod.

    maybe worded slightly wrong, I now see why you assumed I micro coil around the cotton. was stating this to someone who uses silica so by me saying the kanthal is too tight, I meant that there is too much cotton in that coil, same thing when I mentioned a loose coil, that was meant to say there wasn't enough cotton in that coil. so in other words you reiterated what I said, getting the correct amount of cotton is the key, and there again this is why traditional cotton is much more tricky compared to silica to get right.
