Hi, I'm sure everyone gets tired of people asking the same questions over and over but I honestly couldn't find a straight answer. My question is what does the different gauges of kanthal mean? I have 28 gauge right now but I'm not entirely sure what it means. I'm also curious on how to sub ohm build... Like I know that's a very general question but I just don't fully understand how everything works. I can wick fine and I know what cotton to use but I just don't understand the concept of the difference in kanthal wire.
