Well I think I burnt my last coil from dry burning, I was holding down the button on the vision spinner 2 for like 5 seconds multiple times on 4.8 volts. And then I washed it under water before letting it dry and changing flavors, to my surprise I was getting burning tastes, and this coil was a day old. Any explanations?
Welcome to the forum.
Did you wash the atomizer prior to dry burning? As that will definitely cause the flavor your experiencing at this time. It's mainly due to the residue coming from the coil leaching into the fibers of the silica wick as you were washing it.
The good news is that the wick isn't necessarily burnt due to silica being highly heat resistant. In order to salvage your atomizer, you must wash it again and then dry burn.
When dry burning, only pulse in one second intervals. Then give the coil a bit of time to cool down after about 3-5 pulses. The reason for this being that if you continue to dry burn. Then it will stress the wire to the point to where it will short.
Repeat the first two steps and you will eventually the coil glowing orange. If it glows evenly during that time then your done. However, if you notice that one side is glowing while the other is not, then you have to be a little careful. Since, you can increase the chance of short in your coil. Allow more time for it to cool down. Then carefully continue until the whole coil is glowing orange. If you notice any crud, then lightly brush it with a toothpick or paper clip and blow it off of the coil.
