Make them anywhere from just <.2 and up to 26AWG. Always try to leave about a min of 20% headroom in the batt. But these are s t r a i n wound and such tensioned
Kanthal closed or contact coils run very on spec, efficient. That is to say, cooler. An optimum of power is delivered to vaporization. It's not that this is coming from the ether, it's that a lot of waste comes from inefficient contact (to wick and wire-to-wire). If you read some of my stuff on strain and symmetry I think this will help.
Next comes…how do we get there? Two ways: hand and drill winding, once you gain some experience just how much strain is needed for a given gauge. Strain in the end is stretching not much is needed but it's more than just pulling on the wire and
must be consistent. Then you see a behavior quite the opposite of what most folks believe is optimal — they do not fire inside out! They mostly fire end-to-end and it does not require compression (squeezing) to get there. The deficit of forcing wire together is that they tend to return to their original unforced state (like coiler winds). A tensioned microcoil tends to constantly pull in after heating to it's natural cool state or the symmetry originally achieved when it was strain wound.
The take away? More actual vaporization at whatever res you're winding. Coils last much longer. The symmetry most often surviving the life of the created ceramic
alumina layer created electrically pulsing these vs. turned or formed coils. The effect is what appears to be a
cooler output at the same mech res. Which is to say, more effective vaporization. A side advantage is less battery stress/life as you can get an often better result at a higher res. Or, drop it on a variable and get very impressive vapor density for even less wattage.
Tensioned Micro Coils. The next step.
Protank MicroCoil Discussion!!
Start with a straight wire 23 AWG at about .25-.27Ω (18650) and you'll see. The parallels are for more contact surface area for the wire mass (max output).
Remember you would be building a higher vapor density. You can take this greater production and amplify volume by adding air flow at atomizer (inlet) or through the DT and draw used. Best of all worlds really.
LMK if I can help.
Good luck.
