Need advice. How to remove uneven spots when dry burning coil

[Alphantor]

So I have a problem when I try to dry burn a new coil before using it gets really hot on one of the coil loops but the others don't. For example if my coil has 4 loops (don't know proper name) 1 or 2 get red very fast the others get hot but they don't turn red.

It's making me lose flavor and my coils burn out faster. What do I need to do to prevent this?

Also using wotofo 0.28 coils is it best to spread the coil loops and space them out or leave them touching together how they came out the box?

Thanks

I haven't done it myself @Alphantor because I use spaced Stainless Steel coils in TC mode, but I've read up and watched it done often enough.

You'll need ceramic tweezers, coil installed with wraps together and just enough wattage/power/voltage to make it glow ever so slightly.

Then you rake the coil while briefly firing, so that's scrape along the coil with the ceramic in both directions alternating which way your scraping.

I've even seen some squeeze the wraps of the coil together a little on the odd occasion while doing this.

The result you're looking for when it's right is that the coil will glow from the middle and spread outwards towards the ends of the coil or coils, depending upon the atomiser you're building.

I hope that this is of some use to you.

I heat the coil up a little then gently scrape every part of the coil I can get to with the blade of a small screwdriver. Just be sure to not push the power button while you scrape. The glow should even out pretty quickly after you do that. It helps if the wraps on the coil are all touching. You can heat it up a bit and squeeze the coil with tweezers to pull it all together. Again, don't give it any power while you have the tweezers on it.

Thank you to the both of you gonna try following these steps next time I have to change coils. Sucks cause I didn't know these details before and had to toss 3 coils back to back because they had no flavor because of this
Thanks

Lack of flavour can be down to wicking @Alphantor.

What are you using for wicking?

Wick and Vape Organic Cotton. It taste great when I properly dry burn the coil.

As has already been stated, gently rake the coil as needed until all hot spots are gone. I apply low power to a coil, release the fire button and then rake. That works nicely for me.

I prefer spaced coils in my RBA's.

When dry burning a coil I never use high wattages. We do not want our coils glowing bright orange or red. A dull/dim glow is more than sufficient for a dry burn with any type of wire.

Thank you I appreciate the help. Def gonna follow the steps you guys suggested. It sucks cause I ruined 3 coils today because that kept happening.

I was dry burning at 20watts which I now believe to be too much. Do you suggest I go as low as 10 maybe?
I am using Centaurus M200 and Wotofo 0.28 coils

I would give 10 watts a go. You might be able to go lower, all depends on the coil mass. I'm not familiar with Wotofo coils.

You can do dry burns at 20 watts, but you'll only want to hit the fire button until your coil reaches a dull/dim glow. At 20 watts you need to pulse fire your mod (about 1 second pulses, depending on the mass).

With 26/36 SS316L Claptons, I dry burn between 10-12 watts. More exotic coils with greater mass will require slightly more wattage.

When I use 26g simple round wire I dry burn between 5-7 watts.

And also you don't need to bin a coil if you don't get it right first time, you can just do another dry burn and raking @Alphantor.

But with using cotton it swells when wet so if you're a little too tight through the coil/coils and or haven't got the tails quite right, too long and or too much in them. It'll choke the flow of liquid getting to the coil.

As Mordacai said, too much wick inside a coil can (will) mute the flavor.

General Rule of Thumb with Cotton Wicking: Not enough wick = flooding/gurgling. Too tight in the coil = dry hits and/or muted flavor.

Ideally, you want your wick to be tight within the coil, but not so tight that it moves your coil when you move the wick side-to-side.
When I say tight, I mean you should feel some friction as you move your wick side-to-side. You do not want a wick that moves freely, or loosely, within a coil. Wicking is a total "feel" thing.

I don't know what RBA you are using. If it's one that has juice wells that you place your tails into then each tail should just be touching the bottoms of each juice well.

If you are stuffing the juice wells with cotton, then you need to trim some of the cotton off of each tail. Wick tails overstuffed in the juice wells can also mute flavor.

Wanted to give quick update. Now I know all this sounds dumb but I am new to vaping with pre built coils and RBA.

I tested dry burning with a new coil since the last one also had no flavor. I set this one at 10 watts. Put it on the RBA still no flavor so I tried with a new coil at 22watts same thing again tossed it and tried at 32 watts with the new coil. It did get a little hotter/red but this time I can actually taste the sweetness and flavor again.

So it seems that for my set up dry burning at 32 watts seems to work the best

 

[Mordacai]

Ah, getting more useful information so more ideas.

What ohms is your atomiser reading on your mod @Alphantor?

As that's another thing that won't help with vapour and flavour production, if you have the wattage set too low.

If you've got an android device I've found the "watt calculator" app to be very useful in giving you a workable range for wattage including an optimal setting.

I've used my mod between 35 and 40 watts for the past 5 months albeit using the same 0.28ohm coils. Have had great results good flavor and they last a while no complaints in that regards. My ohms on my mod reads 0.25

 

[Mordacai]

Okay @Alphantor , at 0.25 ohms this is what I get from "watt calculator".

So 42 to 70 watts, with an optimal of 56 watts. So you can go up some if you like.

I can't vape that high anything that passes 42 It loses flavor and becomes harsh

 

[Mordacai]

Hmm, could maybe use a higher ohm lower mass coil or coils then @Alphantor.

This is all part of building atomisers, each one ends up with a different build because of airflow and your preference. And it takes some trial and error.

That watt calculator is a bit of a joke!! I vape a 0.28 ohm coil at 23 watts, if I went that high it would be a terrible vape!

Well yes hehe I understand but I've used these coils for 5 months and they are great! The OG post was in regards to how to properly dry burn. But yeah these coils and that wattage has worked great for me tons of flavor and they last a while too.

100% Mate!!!

Don't need no silly apps to "tell us" what wattages we "should" use.
No app or website can tell someone what is right for them.

Pop a coil in an RBA, adjust the wattage until satisfied with the vape. Done. Simple.

I'm a big fan of KISS . . . Keep It Simple Stupid. IOW, "Common Sense Vaping".
