Quick Question about the IGO W6

[primal69]

Hello, i have the IGO W6 and I've notice that it is very slow to heat up, once it starts going it vapes like a champ but from a cold start it takes a good 4 to 5 seconds before it really starts making vapor. those first few second it just kind of smolders, now is that just the nature of the beast, being quad coils that it takes longer to get up and go or is there something wrong with my wires or mod?
i have it on a magneto and am using 24 gauge wire and that comes out at 0.6 ohms.

Are you saying it happens on your quad coil 24 gauge 0.6 ohm on your IGO W6
but not
on your quad coil 24 gauge 0.6 ohm on something else?

Not surprising for a 2.4 ohm 24 gauge coil to take 5 seconds to heat up at 4 volts.
Is it? I dunno; never tried 24 gauge; should happen with 1 coil too.

this is my first quad coil and my first and only RDA that can handle a quad coil, i was just wondering if it was normal to take so long to heat up or if something was wrong.

24 gauge is pretty big;
If you can get a roll of 32 gauge, and use multiple strands twisted together to simulate thicker gauge, you can experiment with getting the best thickness that heats up fast enough but still gives a big coil with lots of surface area.

I would be willing to say this is the legit point of problem... running a quad with 24 gauge coils... at .6... man... bump that up to like 28 gauge, decrease the wraps, still come in at .6 and get a quicker vape...

im actually trying to figure how you can fit 4 2.4 ohm coils of 24 gauge in anything we have now... those sound like some monster coils man...

not 2.4 omh coils......24 gauge coils that come to .6 omhs in the build

 

[primal69]

i'm going to try the 28 gauge and play a lil with the twisted 32 later on, i went with 24 as i was trying to build it from a vid on the net which said to use 24, thanks a lot for the input guys

4 coils of 2.4 ohms each, comes out to 0.6 ohms.
Each of your 4 coils is 2.4 ohm.

At the battery nominal voltage of 3.7 volts; that works out to 5.7 watts per coil.

ok, i'm new to all this and the math of it, i thought that if one coil was a resistance of 2.4
and there were 4 coils that would simply be 9.6, i would imaging since my readings of 0.6
from the addy that that would make each individual coil a resistance of 0.15 providing a
combined resistance of 0.6, if that isn't the case then i am completely confused on the math.

No; the multiple pathways actually add up to lower resistance.
two 1 ohm coils add up to half ohm
three 1 ohm coils add up to 1/3 ohm
four 1 ohm coils add up to 0.25 ohms.
ten 1 ohm coils add up to 0.1 ohms

the actual formula is:
1/r = 1/r1 + 1/r2 + 1/r3 + 1/r4 etc.

ok, thank you, so to get the resistance of the individual coils you multiply the resistance, .6r x 4c =2.4 per coil, and if i only had 2 coils and my resistance is .6 then my coils would 1.2.

 

[primal69]

i tried rebuilding it again, one last try with the 24 gauge but much smaller 8 wraps on a 1.0mm screwdriver 4 coils came out at 1.12 with a total of 0.28 ohms, the thing shot to life right away

Yes; if they are each exactly the same coil (length/gauge).

In reality of couse, each coil is going to be slightly different;

So how about some information overload: let's see:
Let's suppose you make up 4 coils and they're around 2.4 ohms but they're slightly different:
2.2, 2.3, 2.4, 2.5
The average there is 2.35; divide by 4 you'd get 0.5875
Actual coil resistance = 1/(1/2.2 + 1/2.3 + 1/2.4 + 1/2.5) = 0.5862
So they boil down to practically the same thing if there's only slight differences;

Buy what happens if 3 of them have the same resistance and one has some serious difference: let's say half the resistance of the others - maybe some of the wrapps are shorted out:
So lets say we have the following 4 coils
2.4, 2.4, 2.4, 1.2
Actual coil resistance = 1/(1/2.4 + 1/2.4 + 1/2.4 + 1/1.2) = 0.48
Not a huge difference in a sense by big enough for a subohmer to care about.

I was with you up to this point... Here I completely wholeheartedly disagree... in theory the 1.2 coil does not make a huge difference, aside from the additional 6 watts that .1 ohm would make (30 and 36) respectively... but more so the difference in heating time would be insane...

that 1 1.2 coil would be cherry as the other coils are starting to get an even glow... the biggest thing when building multiple coils is to replicate the same coil, the same ohms as best as possible... to give you an idea... merely the length of your leads can cause a set up to fire unevenly... this is a bad thing... you do not want to have one side firing sooner than the other... odds are if you dont know its happening you wont notice it... until you burn the cotton on one side of your set up while the other side is still nice n wet...

just saying... this would be more precise but i got distracted a few times in the course of writing this

Yeah; that's kinda what i said; 0.48 compared to 0.6 ohms is:

[Wickeddeuce]

Yeah; that's kinda what i said; 0.48 compared to 0.6 ohms is:

the point i was trying to make is not a huge difference in a sense... sub ohm or not... one coil being a drastic resistance different than another coil is HUGE, aside from uneven heating and various issues of not having NEAR identical coils... you run a serious issue with running too much current through one coil as compared to the other coil and actually melting the wire, causing the coil to sink, touch the atty and short out... or melt sever connection and possibly form a short... there are any number of various serious consequences from uneven coils... is it to say that it is guaranteed to happen? no, but is it possible and dangerous? yes, extremely...

so it matters to far more than just a sub ohmer...

before i go ahead and post this i am going to add, that while using 30 gauge and creating dual coils, i actually did melt some wire on my first attempt, upon firing the mod, watching them heat up to ensure a good coil, no hot spots, heating from the center out, etc etc etc... the one coil rapidly sank...
