Are hotspots wick related? Is flavor wick related?

[bizzy511]

I have been doing some research on building coils, more specifically a micro coil, and I was wondering, are hotspot problems wick related? It seems like every time I read a problem or watch a video about a hotspot, the wick being used is SS mesh.

Will hotspots also appear when using a cotton wick?

My second question is, is the flavor based on the wick material? If I made a micro coil with the same ohm, but one used SS mesh and the other cotton, would they taste identical?

which SS mesh is recommended? 400 or 500 ss mesh?


Thank you

Hot spots can happen on any wick material I think you just see it more with mesh because its conductive. Regardless of wick material you want your coil to light up from the middle out and light up evenly, if its not doing that you can poke around with it until it is.

Wicks and taste vary from person to person. I like cotton and use it on pretty much everything but I have used mesh and silica, to me the cotton tastes a little cleaner.

When I use mesh I normally use 400 and it works well for me.

I like ekowool for my wicks, but have just started thinking about trying cotton. The ekowool is definitely better than the stock wicking in my PT 2 coils.

I rewick with a 100% cotton yarn.
It's the best I have found for taste, ease of use, rinsing out to change flavors, and absorbing juice.
Cheap too. It's also a lot easier than trying to twist one out of a Q-tip or cotton ball.
So ... another vote for cotton

awesome, thank you both for the input.

Sontu, how often are you replacing the cotton?

Hot spots can occur when coils are uneven or loose

Will hotspots also appear when using a cotton wick?

When used with micro coils, hot spots will rarely occur. The issue then becomes wicking potential. If your cotton densities are not correct, to tight or not enough, then juice can't be wicked adequately and can get dry hits which gives the same vape as a hot spot would.

My second question is, is the flavor based on the wick material? If I made a micro coil with the same ohm, but one used SS mesh and the other cotton, would they taste identical?

Flavor is influenced by wire, wick material, ohms of build and watts vaped at and in which atomizer.

which SS mesh is recommended? 400 or 500 ss mesh?

Which ever works best for your builds is best. This is subjective and is dependent many variables.


Thank you

hope that helps.

I replace it when I change flavors. In my drippers that's usually once or twice a day, tanks may go 2 or 3 days. I mainly use micro coils so its just a matter of pulling the old out and threading in a new one. Its not that it needs to be replaced but its easier than trying to clean them plus I picked up a 2,100 ft cone of cotton yard from Yarns - Cones | Peaches And Creme and a couple of bags of cotton balls so I'm set for a very very long time on wicks.

any good information is helpful and greatly appreciated. THANKS!!

Ok nice. its good to know that replacing cotton does not require a rebuilding of the coil.

thank you

Hot spots can be wick related if you're using mesh and you haven't formed a proper oxide layer. Most of the time it's from kinks in the wire, maybe non-uniform coils, un-evenly spaced coils, or coils touching, and there's probably some more reasons too. Flavor is more coil related, and having the optimal hold on the wick where it's not choking it to slow the wicking rate down, and to not have it too lose where in the process of creating vaper it becomes not in contact with liquid at parts or throughout.

Most people like 400, and people that tend to use high VG ratio like 500, or so i've read... but there was a interesting post by a user with the name Boden who recommends i think 500 for all ratios... The post is somewhere in the multijillion posts found on this forum, but Search might help... might.

With microcoils, all the coils should be touching creating a larger surface area, and heating from the inside out. You're less likely to get a hotspot with a microcoil as long as you keep everything uniform and the coils are touching. Also try and prevent the leads of the coil that go into the positive and negative terminal kinkless.

This is an excellent video (from one of our own members Superdrifter I think) all about micro coils. He explains how to eliminate hotspots with them (at 3.25 he has a hot leg on his coil) and shows exactly how to put in a new cotton wick - it takes literally less than 30 seconds.

You don't need to use the coil jig he is talking about in the video... but look at that thing, it is a work of art.



Finally this is a build for a bottom feeding RDA, but you can use the same method for making microcoils for pretty much any device.

thanks dude. I am definitely a visual learner. I appreciate the link!
