Need tips on Mutation dual coil build

[latexyankee]

I've been away from dual coils for awhile, mostly because I've lacked the power to push them. Now running a hexohm V2 so plenty of power.

I'm looking for a good build that will let me push around 80 watts. My current build is 6 wraps 26ga roughly 3mm diameter. This measures to around .35 ohm. It vapes great until around 60 or so watts then its dry and burning even on the first pull, fully saturated. It's not about the watts race, I just want that super warm tasty vapor.

I believe it could be my build, a hot leg specifically. All the build I've seen done on the Mutation v4 have the one leg connected to the positive post that is farthest from the negative post. Basically, instead of using the positive post that is nearest to the negative, you are skipping that one for the next one which is causing one leg to be longer than the other. I'm assuming this is center the coil best.

I wonder if I should use a thicker diameter coil or just work on tucking the legs into the juice well. Any tips would be appreciated. When priming the coil the legs do get a little red nearest the coil but they do not stand out like a true hot spot would look like.

Thanks!

Pick up some 24 gauge, you'll have much better results.

I personally prefer 22 gauge Nichrome 80, but I run low builds in the .12-.18 range.

The reason you're not able to vape your current build is because it's higher resistance wire, it gets much hotter and you saw the results of that.

I agree. 26g is for RTAs or low airflow stuff like a Magma. For a mutation you should be using 24 or even 22. If you did the same build with 24g around a 2mm diameter, you would be at about .21 ohm. This will work, but with all the airflow the mutation allows, it still might not be as warm as you want.

Well I can try some 24 later tonight. However I dont want to go any lower than around .35 due to the safety precautions of the device. Hexohms are recommended to build higher than .3 ohms.

24ga 8 wraps I suppose. Will test tonight

A 24ga dual coil 6 or 7 wraps 2.5 or 3mm will get you right around .3-.35

the reason the "recommended" build for the hexohm is .3 is because the OKL-T/20 DC/DC converter they are using is rated at "110w" at "5.5v" and "20A". In all actuality, that's a circular ohm's law equation that says your "max lowest build at maximum voltage" is 0.275ohms.

I have personally built a few boxes using that chip and I can say that I've actually put some 0.18ohm builds on one and power tested it at 5.5v, which comes out (using ohm's law) to around 170w. The converters are very stable when pushed just beyond their limits.

If you want to go lower in ohms, just lower your voltage as well (unless they have some sort of low ohms protection that I'm unaware of). Hell, I feel the lower I build, the less voltage I need to push to get it where I'm happy.
