Resistance Wire - Kanthal/Nichrome

[JeremyR]

Well I was speaking of the sense of power your getting out of it. I vape strictly tobaccos. I do not run it at 5 volts all the time just saying micros give better performance, many times people are going lower ohms to get better performance. With micros you can be much higher in ohms and get similar or better performance all around. (The number in my head is half, 3ohm micro = 1.5 ohm in certain aspects) In other words if your wrapping regular coils to 1.5 a 3ohm can give you that performance your looking for. I have been doing 32g kanthal because it's all I have had, so I've worked with it.. But I'll have budget soon for some 30 and 28 g Nichrome.

Air flow plays a large role in performance of hotter coils. Micros are a lot of mass heating up.

I wrapped 3 coils today. The first turned out a little too high for my liking at 3.5 ohms. I used it for a few hours and decided to try for the mid 2 ohm range. The other two coils ended up at 2.4 ohms. I just did not like the 3.5. Since I use twist batteries at work, I need something a little lower. The 2.4s might be as good as it gets for my evod heads.

HazMatt,
Have you done micro coils in the EVOD/BCC yet? I did one in a Protank II but, was afraid to dry burn it as I heard that it would burn through the rubber insulator on the bottom that seperates the ground and firing pin...any thoughts on this?

 

[HazMatt]

I am wrapping micro coils with cotton wicks. And I dry burn every time I change flavors.

I dispose of the old wick, rinse the tank thoroughly, dry with paper towels, dry burn the coil, then replace the cotton wick.

I dry burn with the power all the way down, 3.2v on a twist or 3v on my vamo. I pulse the fire button for about 2 or 3 seconds at a time. I keep pulsing until the coils are glowing nice and clean.

I was going to ask a similar question. It looks like I found part of my answer. I need a lower awg size. Maybe 28 awg.

I have started rebuilding my evod/protank heads. All I currently have is 32awg Kanthal a-1. This seems to work fine for rebuilding to a stock coil style...4 to 6 wraps spaced evenly apart. This has been giving me 1.5 to 2.3 ohms.

However, I want to try some micro coils in my evod/protank heads. I would like to make coils with 8-12 wraps (depending on what will fit in the head) so that I have more surface area. 4 wraps of 32g mashed into a micro coil is ridiculously small. I want to keep the resistance around 2 ohms because, I use these on twists and spinners while I am out and about or at work.

I am also going to purchase my first rda soon. Probably an Igo-W. The 32g wire should work fine for my intended dual coil builds. Building two coils at 3.6 ohms each should give me the desired 1.8 ohm resistance if, I am correct in my thinking. The reason I want higher ohms on my rda is so that I can use it on my SiD or Vamo.

I know, this is not as sexy as sub-ohms on a mech. But, this is keeping me satisfied and off of the stinkies. And, I don't own a mech or dna20 mod...yet ;-)

You can accomplish what you are going for by doubling up your 32ga kanthal and twisting it, should result in a resistance close to 27-28ga.

Thank you. That was awesome information. I will keep it as part of my notes.

I have what is hopefully a quick question about wire gauges. Is there a reason why the commonly used gauges are even numbered (28, 30, 32 etc)? Are odd numbered gauges not a good choice?

 

[pdib]

Odd numbered gauges work great. Not quite as readily available, mostly found in Kanthal. Come to think of it, I've never seen odd in Nichrome. Sometimes it's just what you want to achieve the # of wraps and resistance you like best.

I have created a coil resistance and size calculator for Microsoft Excel which is attached. Give it a try and let me know what you think. I am also working on an application to do the same.

in case you would need it while :
- traveling or so...
- willing to convert between different metric system

more will come shortly

Ok, so I'm starting to think about getting into rebuildables.
Looking at the chart, it looks like the thicker the wire the less resistance?
For example:

30 awg (Ω/in)----- 0.7
32 awg (Ω/in)----- 1.2

The 30 awg is thicker than the 32 awg? I thought a thicker wire would more resistance.

 

[Dusther]

think of it as a highway that electrons flow on.. the thicker the more lanes they have so less restriction on the flow.

 

[McCordRM]

Nice analogy, thanks.
Now to figure out what rebuildable I want. I don't do dripping, so I need a tank. Preferably a 3-post.

If I want to make mostly .2-.4 ohm dual coil RDA builds, what gauge Kanthal A1 should I go with? 24,26,28?

Edit: Yes, I am aware of battery safety. I have Sony VTC4s and I know not to overwork them. Just wanted to say this in advance as I know you all are great guys and will want to look out for me!

 

[pdib]

twenny fo' . . ..

 

[pdib]

Oh, btw; kanthal REALLY starts to show it's weak side down there in the fatty range. It's slow and kin'a limp. A 26 Nichrome build (=25g Kanthal) at .4-.5Ω may prove more satisfying. . . . . .definitely will kick harder/faster. Not sayin', just sayin'

You can get Vaper's Tool box for £0 maybe just have advertisement supported, I'm well aware of time taken etc but launching an app even at 50p when there is already one available.

 

[pjmarkert]

Like mine, it's free: see attached

Why would 32ga. be better than 28ga(My go to gauge) for lower ohm coils. I build .4-.6.7ohms with regularity on a 5/64th bit w/ 7wraps of 28. on a dual rda.Nimbus,Igo-W.
