Kanthal gauge explanation

[matthew2478]

I am still experimenting with wire.

Currently using .6 flatwire and .30 gauge wire.

I have a question on how many wraps to go subohm using .30 gauge. I have used 28 gauge but it seems to be no different. On the .6 flatwire 3 wraps usually getting about .4-.5 ohms. In enable to get that low how many wraps should I use to get that low on a .30 gauge or should i just purchase .26 gauge to get around what I'm going with the flatwire thanks.

I use 27 gauge Kanthal with a 3/4 wrap on a 1/8" drill bit and get about 0.6 ohms in a Genisis. I would try the same gauge wire with a coil less to get about 0.45 ohms in that rba. If you're making different diameter coils the numbers change. 30 gauge wire will require fewer wraps and almost certainly give you burnt hits.

What battery are you using for this build?

I am using a AW 18650. I seems when i do a 4/5 wrap I get .8-.9 ohm.

If it's the AW 2000 mAh the amp limit is 10A and you'll be right at that 0.4 ohms. The 1600 mAh AW has a 24A limit, so you're good to go. Do you know know about battery safety for vaping?

OK, that 4/5 wrap is with 30 gauge wire, correct? If you reduce the number of wraps to shorten the coil length for less resistance, you'll have too much power on the wire surface area. You need to go with thicker, lower gauge wire to solve that.

For an idea of how much difference wire gauge makes to resistance, have a look at the first post in this thread. It's the second item under the Ohm's Law Calculator. There's also a lot of information on sub-ohm vaping there.

I know somewhat if battery safety. And thanks I will try going with a thicker wire? Do you think getting some 26 gauge would be fine.

I also have an efest 18650 1600mah that that has a limit of 30A

26 gauge will allow you to make coils in the resistance range you want. In the end though you have to experiment yourself to find what works for you.

You didn't say what AW battery you have. Be careful not to put too much current draw on the battery. If you do it will start heating up and if it gets hot enough it will vent. Once that starts it can't be stopped and that can become dangerous
