Resistance / Coil gauge / Heat - Newbie Question

[NickJ]

Hi Guys,

I've got a question I was hoping someone could help me with! Please bare with me it may take a second to process my thoughts...

Recently started rebuilding, on the Kangertech subtank rebuildable deck. First time I've rebuilt and have been trying out different resistances uses increasing decreasing wraps etc. Have tried 0.5 up to 1.6 ohms running it on the yihi sx350, using Kanthal 28g. I am trying to hit a sweet spot but I am not completely there yet!

What I have noticed that at 0.5-0.6, I am getting a hot vape and cant really go past the 23W level as then I get the nasty burn taste, at that resistance I am finding 20w works for me, which obviously outputs about 4.2V. I was convinced i needed to go sub ohm to find what I was looking for, big clouds taste etc. As an experiment I've just built a 1.6 coil. And instantly can see the difference, much cooler vape, longer hit overtly more satisfying. I have then increased the wattage and have easily gone past 23W. I am know on 26W and I think I have found to a degree what I was looking for. What I have noticed the clouds produced is possibly better. Now is this due to the fact I can go past 23W on my built of 1.6?

So for the sake of experimentation if i wanted to go past 23W on 0.5 without it burning, could I just increase the thickness of the coil wire?

I know the easiest os just to try put i wanted to reach out and see what you guys think first. I would love a semi scientific explanation how I should be looking at this..

Your help greatly appreciated!

When you have a higher resistance coil you have a longer length of wire. You'll have less wattage per inch so the heat at any one point is less.

23 watts is 23 watts whether it's into .5 ohms or 1.6 ohms. I think you've found your answer in the higher ohm load. This is easier these days with mods that put out higher voltage. In the past when you were stuck with 4.2 volts you had no choice but to wrap a low resistance coil

As far as increasing the thickness of your wire for a 0.5 ohm load, yes, that will make your wire longer (less wattage/inch). Not sure if it's worth messing with though
