I have honestly hated this vape since I bought it. I just can't get it working right. Yesterday I had both tanks making great clouds by themselves, but doing them together would make the fuse turn off the vape. I had somebody redo the coils at a higher resistance (ten wraps for each coil, the coils are some unit of measure that states 24) and now both tanks will fire at the same time but even then the clouds are tiny and not thick in the slightest. I'm so pissed off right now. I watched a YouTube video of a guy who had his set up perfect and the vape was making amazing clouds. All I want is for the vape that I paid good money for to work properly and so far this has been ridiculous. I read that the earlier versions of this vape cut off at lower than .4 ohms, but the newer ones (Serial numbers above 100) have a much lower resistance cut off point. My serial number is above 500. Can anyone help me out here?
Just from the limited amount of information I have about your setup, it seems to me that when your coils were re-made for a higher resistance the person building them should have thought to maybe use a slightly smaller wire (perhaps a 26 gauge). What it seems to me is happening is that now you have much more metal to heat up (10 wraps of 24 gauge is a good bit of wire to heat up if you don't have the power to do it), so it's barely getting the coil hot enough to make good vapor (that you would like). Below is an arbitrary example of what I'm referring to:
A coil made from 24 gauge Kanthal wrapped 10 times around a 2.4mm screwdriver would give you about .75 ohms... to heat that coil properly (subjective to my taste) it would take about 50w for just that one coil. So for your setup you need a minimum of 100w or you're not getting those coils hot enough to vape and make a "lot" of vapor (again, subjective)...
If you were to make the same coil @ .75 ohms, only with 26 gauge Kanthal, you could make it with 7 wraps instead of 10, which is a lot less wire to heat. It would only take about 25w to fire that coil really nicely. This cuts the needed power in half just by switching to 26 gauge wire. I'm pretty sure that even with the smaller wire, if firing properly you would get plenty of clouds if that's what you're after.
Hopefully I didn't butcher that explanation badly enough to where it didn't make any sense...
Long story short, try with smaller wire @ the same resistance - or - bring the resistance down a little bit by trying 1 less wrap at the wire size you have.
Again, this is purely intuitive and not knowing much about your setup.
