@KayOhBe ...to answer you first because when I gave away my RDA deck to another vapor that managed to break his I only have the OCC heads to rebuild and I started out with the exact same build as you, maybe except for a different ID....and I had the same wicking issues....I vape the stock heads on my VS rDNA40 (kanthal heads, not nickel...I don't have any nickel, temp limiting is not something I am big on, it's a nice toy but it irritates me, but that's for another story another time,) anyways the build would come out to just below .7ish....like .67 or so. And I would feed what felt like almsot too little wick so I would let the wick stick out the holes a bit then cut it figuring it would work just fine...then I would basically flood the coil assembly with eliquid, put it in my tank, wait a few minutes, take a few unpowered primer puffs and and then start vaping....and the first few hits would be awe---sommee! and then....dry hits of doom and I would have to suck on the thing unpowered for several primer puffs again and then I would get a great vape for a few more hits and repeat....all at the amazing high power of about 24.5 watts....
Sound familiar?
The OCC chambers are a "Bermuda Triangle" or sorts and don't play by the rules so you can't either...if what you're doing solved the problem then great, keep going with it....what I found that I ended up doing that works for me is I pre trim the wick so they are barely long enough to get to the juice inlets...this took a few tries to get the right length. Then I gently take a couple fingers and run them down the length of the wick to make sure all the strands are going the right way as much as possible and then I put a single drop of juice on them and fold them up....just one drop so they will stay together but they aren't soaked enough that you can't fluff them again inside the coil. I fold them up so once I pull them down into the coil I can push it against the roof of the chamber to straighten them back out. Then I take a toothpick or a 20 gauge needle and work them into place so they're still running straight as possible around the juice inlets making them as fluffy as possible in the center...then I poke the center of the damn thing with a needle to make a hole in the center for liquid to rush to the inside as well...I kinda have been working on this and it's more a beta type thing but I started taking a needle to the center of my stock coils and fluffing them and I don't get dry hits at all up to 25 watts....when I've mastered it so it works at 30 without a dry hit I'll make a better "hot to" guide...it's not as hard as it sounds...it's just hard to type out descriptively with out it sounding hard
@Xavierrr .... welcome to VU bud
Everyone here is doing our best to help you but you need to calm down a bit, and relax...we will get this figured out but we need a little more information and pictures if possible to help explain what's going on with your tank. I will start off by saying that your tank comes with three different coils as you know...they are all different, none of them are the same...
There is a .5 Ohm OCC coil that works good set from 15-25 watts.
There is a 1.2 Ohm OCC coil that works good set from about 10-18 watts.
There is a RBA deck with a pre-wound .5 ohm coil that has much smaller juice inlets and works a little different than the other 2 and your wattage settings may vary but again 25-27 watts is probably the max for that little coil.
Now, if you just screw in any one of these heads and crank the power up to 30 watts or more and start ripping away at these coils they are going to burn out fast, the RDA one you can rewick and possibly save but the other's will have to be rebuilt more than likely.
You say you primed your coil? Did you put a couple drops of juice on each juice port on the sides of the coil and watch them soak in?
Did you put a couple drops into the top of the OCC coil heads or directly onto the RDA coil before you closed it up and watch it soak in to make sure it soaked? Once you screwed your tank together did you let it sit standing up straight for a couple minutes and take a couple unpowered puffs to make sure your coils were completely ready to go the first time you put a new one in?
Did you start your wattage lower and work your way up to a higher wattage to break the coil in or did you just crack 'er up and let 'er rip?
Are there any chips or cracks in the glass of your tank or any small leaks around your o-rings?
I am asking all of these questions because depending on your answer it will help us be able to tell you what's going on with your coils and your tank. In the mean time if you have a vape shop near by I would go down and buy a single .5 ohm coil if they have them and prime it like I described above and then start it off at about 15 watts and work it up to 25 watts and just vape it there for awhile and see how it behaves....again, this will help us and you figure out what is going wrong so you don't have this problem again in the future or can fix it if you do.
We're here to help you bud, we will get to the bottom of this...we just need a little more info
