Alright guys. So it is possible for my 0.3 ohm coil to vape at 30-40 watts without getting burnt taste? Only if i rewick it right?
Yes it can handle higher wattage. What gauge kanthal are you using? It looks like 24 considering the resistance and the number of wraps.
You want to make sure your coil glows evenly without a wick, that ensures you don't have any hot spots. Make sure your coils are not touching the sides of the chamber either, it can cause a short.
Once your coils are glowing without hot spots, you want to wick it snug, but not tight. RTA's are a little tedious with the wicking, so make sure you have enough to just get into the tops of the liquid channels, you don't have to fill the channels with wick. Once you're satisfied with the wicking you can prime the coils with a few drops before you reassemble the tank. After you fill it you'll notice some air bubbles rising through the tank, that tells you that the wicks are working well. Once you let it sit for a minute it should be good to go. It takes practice on the RTA's.
