Help with heat!!

[bris1974]

Hello experts!! I have two RBAs that are too dang hot of vape. The first is a dripper set up at .7 ohms with 28 gauge kanthal, the second is a tank with 500 ss wick and 28 gauge kanthal at .9 ohms. I have 1/8 inch hole in each cap lined up with the coil. Problem is the vapor is too stinking hot to vape. burns my throat pretty bad. i'm using 8mg nic in approximately 20/80 mix.

Any suggestions for a cooler vape with same set up? would an even bigger air hole help?

Thanks in advance!

I may be wrong, but that sounds alot like your wick is not wet enough with a high wattage vape. That is, if you're sure it's not hot spots. Maybe try tilting more when you take a hit.

Edit: well, at least as far as the genny setup. The dripper, I'm not so sure. Are you adding a goodly amount of juice?

for the genesis device, when the tank is full and the top cap is off and you fire it with the mod vertical how long will it vaporize without the coils glowing?

If I tilt it first to get wick saturated, then place vertical and fire, it will fire about a good full second before I can see the orange coils. starts vaporizing immediately, but a second or so before the glow.

that may be part of the issue. I've been experimenting with the genny, and if I tip all the way horizontal on each hit, then seems to be cooler. Maybe the wick is a little too dry...?

Ok. more playing and fiddling. I definately think it was a dry wick issue. I really soaked the wick on the dripper and now its hitting like a champ. no heat issues at all as long as it stays good and wet. with the genny, same issue. if i turn it horizontal a second before hitting it, it stays nice and cool as well. I guess I vastly underestimated the proper wick wetness with these low ohms.

Thanks a ton for your guys help!! I'm in vape bliss now!

with a good wick & coil you should be able to hold it upright and fire it till the tank runs dry without the coils glowing, well maybe not that long but when I vaped ss mesh I did low resistance coils, under 1 ohm, and with all that power I was able to vertically fire it with no glowing easily for 30 seconds. so its definatly a problem with your wick or coils. maybe the wick isn't keeping up good enough or your coils are to loose.

definitely cannot do that. I'll try a new coil. Very well could be a little loose as I had to fiddle with it quite a bit.

Thank you Sir!

I always had great luck with the 500 mesh, and like you I use 28g at resistances below 1-ohm. what length of mesh are you using before rolling? sometimes at these higher watts using more mesh is better. personally I used about 100mm for a 1/8 wick and oxidized it. what mod do you use for the genesis?

Try a silica hybrid. Wrap a piece of silica in the mesh, leave a good sized tail sticking out into the tank.

I'm vaping a short SS mesh wick (extends about 25% of the way into the 3 mL tank) with 0.8 ohm coil and I have to tilt more to keep the wick wet. Otherwise, definitely get harsh vapes.

I will try that. thanks for the tip!

I am using 500 mesh, but my wick is a bit smaller than 1/8. I can't tell you the measurement, because when I first started RBAs at higher ohms, it seemed really easy and any size wick i tried worked. Since then I just started "eyeballing" the mesh size. I will definitely measure my next go at it. dripper is working beautifully, but still trying to dial in the genny.

That sounds dangerous... Quite a load for your battery! Please be careful. Anyway SS cable is way to go on a genesis. Wrapped in mesh on top then ribbon wire. cable flows juice like a dang faucet. Just make sure there's some play in the wick hole, don't choke it. Most of the juice travels on the outside of the cable, different than mesh.

its been 4 months since vaping ss mesh, only use porous ceramic now. when I was doing the mesh, believe me I always knew what my batterys were doing. I did and still do use hi quality batterys with high amp limits. still with even that amount of mesh I didn't have to sit there and hold that fire button any longer then any other set up out there. in fact with using the porous ceramic now, the heat sink with these is more then with the mesh. haven't vaped a cable but how is the heat sink in that?

It does seem to absorb a little more heat, but not too noticeable. When I pick it up cold, it usually takes one hit to warm it up, then it starts really cooking. I run them about .7-.9 ohms, on an ac9 and an agat+. I can't remember these ever hitting dry.

sounds about the same as a 1/8 porous ceramic wick, I also run those with either 26 or 28g with an average of 3 wraps in the .7 range. I believe the ceramic uses the same principles to your cable wick, although it might wick some I think most of the juice gets to the coils via tha outside of the wick.
