Yes, you can't aim for a target resistance of 1.8 Ohms dual coil. Check out the example I posted above.

 

ok, i just noticed, so the i will get 0.40 on the mod?

 

Per coil. 0.2Ohms dual coil with that example, approx'.

 

ok, you i try to get my head around to this steam machine, so when i select the ohm target that is for coil, so if my atty has two coils i need to multiple times two?

 

Dual coils will halve the resistance of the equivalent single coil, so two 1 Ohm coils will provide a 0.5 Ohm final resistance.

 

Sorry you lost me now

 

If you install a 1 Ohm coil in your atomiser, the resistance on your mod will read 1 Ohm. If you install a second 1 Ohm coil, the resistance will read 0.5 Ohms. I hope that makes sense as that's all I've got.

 

If it’s bending when you are putting the cotton through it, it might be that you are using too much cotton. It shouldn’t be too tight.
