Uneven coils

[Scr81]

I can't work out what's going on. One coil fires much more than the other. They're wrapped the same number of time, they're wrapped around the same thing and I've tried to get the wicks the same.

It gives me a rotten dry burn sometimes and it's 3 separate coil builds I've done now so I must be me.

I'm using a Hana clone and a big Dripper on the top.

I've built the coil using 30awg wrapped 8 times to get around 1.3 ohms.

I generally run the Hana at 18w which is showing up at 4.9V.

You'll see that to one on the right is already showing to be much drier.



Any suggestions are welcome!

Well get the coils working the same DRY.. Then add wick. Then if the issues still happens looks at the airflow and the wick again.

Did you dryburn before wicking?

 

[Scr81]

Yes and they heat evenly and at the same rate. Squished them into micro coils too.

then maybe one wick is tighter than the other.

I never have an uneven coil problem

Single coil

What I do when something like this happens is make sure the coil legs are the same length leading to the posts, and also make sure the wick isn't too tight within the coil.

 

[Scr81]

I've rewicked it as I think one side was a bit tight... Fingers crossed! Thanks everyone.

Are the coils correctly aligned to the air holes. The dry one could be getting more air.

So the op must have figured this one out??

I have a Big Dripper as well, and for me, the problem was placement of the feeding hole from the tank to the coils - it's slightly off to the side, so one coil gets wetter than the other. When I'd fire my naked coils, they were fine. After vaping a while, I'd notice the wick on one side was constantly darker as though it were firing unevenly. After doing some digging on the internet, I found others having the same issue. When I build on my Hobo V2 this doesn't happen. Do you have another RDA you can do a test build on to make sure it's not your technique?

When wicking your BD, try running some wick from the dry side to the wet side.

Cause the big dripper pretty much drops over one coil you're probably not squeezing enough. Juice out to wet both wicks
