Coil Help Please

[Heath54]

I am new to making my own coils. I would like the know the difference between spaced coils and touching coils. Also the advantage and disadvantage of both. Thanks to all who reply.

Hi Heath...

Some say that Touching Coil yield better Flavor. It's all kinda Subjective to me.

I think the Only way to know for you what you Like Best is do a little Testing.

A lot of opinions on the differences, I haven't noticed much when it comes to flavour or vapour production. Touching coils are more rigid and therefore easier to rewick, but can be difficult to get to function properly in temp control.

I tend to go with contact coils in RDAs and spaced coils in RTAs and that works well for me.

The correct term is "standard coil"(spaced) and "micro coil"(touching).
If depends on the viscosity of the e-liquid you are using. If you are using a VG heavy e-liquid then use a standard coil as it will not gunk up as fast, but it will produce less heat mass. A micro coil will produce more heat and vapor, but will tend to gunk up faster with heavy and sweet e-liquids. Most pre-made coil cartridges are standard coils, this because it can accept a wider variety of e-liquids and manufacturing tolerances are more easily met as they are churned out like a machine gun and also today with dual and quad coil attys there is isn't a whole lot of space for standard coils in those attys especially when using larger gauge wires.

I've never heard of a spaced coil referred to as a 'standard', coils are either contact or spaced. Micro macro etc. are semi-redundant terms used by some to refer to the approximate size range of a coil.

Macro - 3mm or larger
Micro - 2/2.5mm
Nano - 2mm or less

Thanks for all the information. I guess I will do some testing.

I know it is personal preference, but any specific reason you think you lean towards using contact for RDA and spaced for RTA's?

 

[sonicbomb]

I'm led to believe that spaced coils gunk up at a slower rate, I am less inclined to rewick a tank than an RDA. I also think that spaced coils have a slightly lower heat flux making them better suited to the small enclosures of an RTA. All this is pure speculation, it's just what I have found (I think).

Contact coils heat more rapidly than spaced coils due to the radiant energy being spread throughout the coil more efficiently. Contact coils also tend to gunk up whereas spaced coils don't. The only wire you can't run as a contact coil is ni200, every other wire type can be used for contact coils, you just have to dry burn them to build up a non-conductive oxide layer.
