0.7Ω 28 awg vs. 0.7Ω triple twist 32 awg... Not the same?

[Shiryo]

So for the past few months, I been vaping 0.7Ω with a triple twisted 32 awg Kanthal-A1 4/4 wrap. Today I just got 28 awg Kanthal-A1... wrapped a 4/4 coil and chucked it in my IGO-L and AGA-T2.

I was expecting the same vape experience however I notice that the 28 awg does not produce anywhere near the same vapor. It's almost like i'm vaping a 1Ω coil with the 28 awg???

Thoughts?

Surface area probably.... Never tried triple 32, but it makes sense...

More surface area = more vapor.

Yeah... That's the only thing I could think of... And that makes me sad... I tried spacing out the coils to get a bit more surface area... no effect.

I think he means surface area of the wire not the coil on the wick. The same thing adds to the appeal of flat ribbon compared to round wire.

I also tried to use 32ga twisted to lower it's gauge

it will unravel eventually the wire naturally sags as it is heated
drill twisted heated to hold shape= fail


btw it is a factor loss of 3 gauges so a triple wrap is actually a 26 gauge wrap

the 28 gauge wrapped @ same ohms is a pure
the triple will jump all over the place and may even go lower

use correct gauge wire or get coil burn hotspot nasties
eventually having to rewrap over and over.

twist wrapping, its only good for the legs and commonly used in industry that way..

I'm using double 28, every step in the spiral just touching each other, 4/5 wrap @ .45 ohms. great vapor on a new batt (I'm using a liquid with very low VG though)

Yeah, I know. Was also saying I tried to space the coils out more to cover more wick area and hopefully gain more vapor. No dice.

I've never had a twisted wire unravel itself on me and I run my coils pretty hard... Never had hotspot issues with the twisted wire either, not any more than using 28 awg at least.

Yeah... I'm thinking of trying a twisted 28... Which would bring it down to a 25 awg. Going to order some 22 awg as well. Or triple twist a 28... lol.

I'm not twisting though. Two wires running in parallel next to each other from the negative to positive post. I tried the twisting already but prefer full contact throughout every contact point on the mesh

Trile 28 may get you into sub .3 ohms, that's certainly pushing it.
