To touch or not to touch?

[Lethalp]

That is the question . The belief use to be that coils "can't touch" loads and loads of info out there saying that. I thought they were not supposed to touch, and that if they did that would cause a hot spot or some other danger.

Enter the micro coil, now not only should they touch but u need to steal your wife's tweezers to push them together? I do understand a lil more why that is.

So, do they need to touch or should that not? Is there any danger involved in either way?

Could a mod move this to a proper rebuildable thread please?

Your coils can touch each other, no problem. There's no danger as long as you check for shorts and keep your amp draw within your batteries safe operating range (on a mech mod). If you're using a VV/VW mod it should have built in protection for shorts and amp draw so you'll just need to keep your resistance at or above 1.5-1.8-ish and adjust your power.

With the microcoils it kind of makes the whole coil a hotspot, and since the coils have a smaller diameter and more wraps it creates more surface area to contact the wick, thus better preformance.

Coils touching or not you should be fine either way.

I use micro coils in drippers and 'regular' coils in RBA's on SS wick. I get the micro coils as close together as I can. My understanding is if they touch, oxidation will quickly develop on the wire and they do not short. Whatever actually happens, it works fine

Using non-touching coils on SS wick works too. I try to keep these coils separated but I have had coils touch with no apparent issues. I imagine it would be hard to keep them all touching because getting rid of shorts would be tough.

In any case, the worst thing that could happen is a short between two coils eliminating the wire between from the circuit with a resulting decrease of resistance.
