Chances are, you have a short in your mesh. Re-oxidize the mesh and then recoil your setup.
hey all gg friend, my brass button gets hot fast, and i don't know why. I am coiling at 1.0 to 1.2 ohm, using kanthal wire and ss mesh. i mean is this normal for such a low res coiling?

Did you fold over the visible end of the mesh? the end part of the mesh where it has been cut becomes brittle after oxidisation and is a real nuisance as it will cause loads of shorts.

Do you have a multimeter? if you do, run the probes over the mesh and you should get absolutely NO readings and if you are then its not oxidised correctly.I would guess that its an oxidisation problem which is giving you shorts as that usually is the culprit, sometimes your oxidising will go well and its very easy and then sometimes it can be a real pain.

Did you try the cigarette paper method that was previously mentioned?

i cut it so it flush with both side of the end slot of the ceramic, i guessing it might have touch them very very slightly. i will cut it shorter. as for the multimeter, which settings do i set it up? the resistance?

i viewed the video and learn that it just builds up carbon or something? but still unsure what exactly it does for shorts?

Hi Timmy, ss mesh is notoriously difficult to get to work in genesis type atties so dont be thinking that its only yourself that is having these issues!

The tube of ss mesh that you have made obviously will have an end visible on the tube running lengthways along the tube (hard to describe but I hope you understand what I mean) so unroll the mesh a bit and double the end over on itself so you dont have a cut end on the tube and try that because where the mesh is cut will become brittle after burning and cause shorts. Just fold it flat underneath itself so there is no cut end for your coil to touch. Only a couple of mm folded over will do, your only trying not to have a cut end touching the coil.

Check with the meter for conductivity over the mesh tube, you should get no reading off it at all. Yes use resistance settings on your meter and there should be no readings,if its fluctuating then its not oxidised properly.

The cigarette paper trick puts a bit of carbon on the mesh directly beneath the coils thus stopping any shorting so if you are getting any readings off the mesh with the meter then try this trick.

Good luck and let us know if you got it to work.

Right well the good news then is that your mesh is good to go! that would be the thing I would be checking every single time first off because its the most troublesome.

You must be getting a short somewhere, you have checked your coil as you said and you are getting around 1ohm so next try taking a few readings to find where the problem is. If you put a probe onto the connection pin and the other to the body are you still getting the same ohm readings?
