RDA Help, burnt/dry hits on rda

[Bearded_vaper]

hey everyone , a friend gave me a rda today that he never got around to using, after many hours of tutorial watching i managed to build a quad coil on it but even tho i soak the cotton i cant get a nice first vape it always end ups burning my throat... Its a RJMod Cats clone
I had to end up drillung a bit bigger holes and using another drip tip because there was barely anny airflow , its a bit better but still getting that disguting hit to my throat after a few seconds... It read 0.20 or 0.19 ohms, tryed vaping it at 100w and 125w as all my other dual coil builds work fine at that. Please help me haha

Too much wick and not enough liquid maybe?

I dont get it though, its literally soaked
And the cotton isnt stuffed. I dont know anything about quad coils but once i got it all wicked up and juiced, when i fire it i can see sone parts of the wire glow faster than anny other, and i think those are the points where i get my dry hits from, cotton hasnt been burned yet either :/

It's very important that all the coils fire evenly from the center out. I have a goliath rda that I've put 8 coils in it took awhile to get all the coils equal. I had to fire and watch, adjust and tighten. Repeat.

Straight in with a quad coil eh. Try starting again small and simple with a dual coil and lower wattage. Perhaps post some pictures of your build.

There is your problem. When you hit the fire button and you see some coils glowing where the other coils aren't glowing that means that you don't have something right. It's very important to fire it before wicking to make sure you have all the hot spots worked out of your coils. I wouldn't suggest going straight into quad coils until you get dual coils down first. Pull your cotton, fire it and work out the hot spots then rewick. Hopefully that will help you get a decent vape.

Ive been working on dual coils for a while and always had it fine at 0.15 ohms with twisted coils on my mutationxv4 and my tfv8 cloud beast rda. On my quad coil, before i wicked it, the coils were glowing almost in perfect sinc. But once its all wicked an juiced, i fire it and see on two of the coils, the wire coming from the center pole glows a bit too fast and all the rest works normal, maybe put more coton so that it covers even the wires that reach for the center post? , ive got a few pics of it but for some reason, it wont let me upload them, says that the file is too large :/

Hot spots. Try spaced coils.

Those are hot spots. Have you made sure your screws are tightened down good? That could have happened when pulling the cotton through if your cotton was tight. It could have moved the wire and made a hot spot.

Like Jace75 mentioned, try spaced coils. With spaced I like to wrap coil as normal then grab both sides of coil and pull apart then push back together. That will pull them apart and squeeze them back and they will be spaced just right. I would try that and see if it works out for you.

What wire are you using and what gauge?

I tried a quad vertical coil in a inde duo and it felt like I needed to shave my trachea. Unless someone inhales cigars I don't understand how it's enjoyable.

sorry, that didn't sound very helpful :/

 

[Don29palms]

What about this one then?

That looks like it took a lot of patience. Stainless?

Yep. 26g 316l. To be honest that this is just stupidly ridiculous. It's fun to play with.

It's a Vicoous Ant Goliath clone. It's a 30mm diameter.
