About a week or so ago I received my Cobra 5ml rba. It came with 1 piece of 300 and 1 piece of 400 ss mesh and unknown wire. I also ordered some 304 ss mesh and Kanthal A1 32 gauge wire(this was all that was available at the time I placed my order). I've used up the unknown wire and 400/300 mesh and some of the 304 ss mesh and 32 gauge wire trying to get this thing set up. I've used loose wraps tight wraps, drill bit wraps. I'm using a mini cooks torch to oxidize. I'm dripping juice on the oxidized wick and burning it off.

I've followed PBusardo, as well as others I found on youtube for making the wick and coil. When I can get it to work I'm getting a nasty metalic taste. Also can't seem to keep it working for more than one or two fires, before it starts shorting. I'm putting this on a ProVari.

When I have the coil's made I check ohm's. I get anywhere from .9 to 2.5ohm. Haven't had any do major jumps but there have been jumps from 2.3 down to 1.5 after messing with the coils to try and get them to burn properly. Also getting very little vapor production.

This thing is driving me nuts.

Yes I know I could have gone with a cheaper version like the aga but I have a problem when I go into something I like to go all the way and get the best I can.

Any advise would be greatly appreciated.

No replies. Let me try to explain what I have experienced.

Let me start off by stating that I have not used any genesis type rebuildables, but I imagine the principles are the same for using ss mesh.

The metallic taste is caused by the short, a "hot leg", loose coils, or the wick is not capable of feeding the coil with the liquid it requires. In my experience, most shorts occur on the seam of the mesh. Try folding a small piece over before rolling the mesh, then roll towards the folded section. The wick hole might have an effect on shorts, but I have no experience with the genesis type rebuildables, so maybe someone else might have some advice on the matter.

The tension in the wire is crucial to building a coil. When the tension is too tight, the liquid has a difficult time making it up the wick, and its possible the coil can remove part of the oxidation causing a short. When its too loose, the mesh will not heat up properly, and will also cause that "hot leg", which usually occurs on the center post. When you get the tension right, try pulse firing to build up that oxidation under the coil. Also, make sure the coils are evenly spaced and not touching each other. Try different methods with different gauge wire, which will provide you with the experience to develop a preference to what type of vape you enjoy. Once you find what you like, start perfecting the method.

Wick variations can improve the supply of liquid to your coil. Try different wicks [ solid, hollow, thick, thin ]. I like to use a hollow wick with thin walls and tilt when necessary. The liquid flows down the center of the wick for a quite satisfying vape. The solid wicks take a little more time to wick, but will hold more juice for consecutive pulls.

From my experience with ss mesh, I have found this to solve all my problems. Like I stated earlier, I have no experience with the genesis type RBAs, but the principles are the same. Hopefully someone else with more experience can provide a better understanding.
