Sorry for the noob question, but I've searched and can't find a satisfying answer.
Say I build two different coils of exactly the same resistance from, say, 30ga and 28ga wire and run them at the exact same wattage, what would the difference be in performance?
Is there an advantage to one or the other?
I know I could try this, but currently only have 28ga wire.
I'm currently stocking up for the Vapocalypse, and I don't want to buy anything that I don't absolutely need until after August 8th...
This actually Isn't a noob question at all. Although the Answers you get May Not be what you are Expecting.
Go to this site and put in all the Parameters (Wire Type, Gauge, Coil Diameter, Ohms, Watts) for a given Coil that you have used and Like.
Coil wrapping
Now change the Gauge of the Wire and leave Everything Else the same.
Notice how the Heat Flux and the Heat Capacity changes? Now Notice that as you change the Watts alone, that the Only the Heat Flux changes.
In very Basic terms, you can think of Heat Flux as the amount of Heat a Coil produces. And Heat Capacity as to How Quickly a Coil heats up.
Thicker Wire, of the same Alloy, take Longer to reach a given Heat Flux. ie: they have Slow Ramp Up. Where as Thinner Wires have Faster Ramp Up. This is also true for Ramping Down. Thicker Wire take Longer to Cool Off than a Thinner Wire.
So what are the Advantages? That's hard to Say. And a lot depends on if you are using a Mechanical Mod where you can Not Change the Voltage. Or if you are using a VV/VW Mod where you Can changes the Voltage. Which resultantly, changes the Wattage.
What many people do is Find a Coil set-up that they like at a give Wattage and then Look at the Heat Flux as a Baseline Number. Then they try Other combinations of Gauge, Wire Type, Ohms, etc, keeping that Baseline Heat Flux in mind. And then compare what the effects on Flavor, Vapor, Wicking are.
Hard to say what the Advantage of a 30ga is over a 28ga wire for you. Because I don't know what type of Hit you are looking for? Or if you are Using a Mech or a VV/VW Mod?
For Me, using a VV/VW device and wanting Flavor over Clouds, Fast Ramp-Up over Slow, I build leaning toward Thinner Gauges vs. Thicker Gauges.
