Does wire's heat up time depend on amount of material or resistance?

[johnlikestovape]

Let's say I have two coils, both (let's just say) 1.2 ohms. One is made with 30 awg Kanthal and the other 32 awg Kanthal. Obviously the 30 awg will have more material than the 32 awg. Will both of these coils heat up at the same rate? Or will the 30 awg take longer because there is more surface?

Just a question I've been dying to have answered. Thanks!

It is the resistance the determines how fast they heat up so they should both heat up at the same rate.

Thanks Manimal! Appreciate it

I've been hoping this was the case.

I've found that the heavier gauges heat up a little slower, but the difference between 30 and 32 AWG isn't much at all, it only becomes noticeable at 26 and above.

 

[danny4x4]

I would say it does make a difference for me. I've tried 28,30 and 32 gauge.
28 seems to take perceptibly longer. Hence I stick with 30. But bear in mind it's just my opinion. You may have a different preference. Only way to know is to try them all.

Happy coiling!

With microcoils, it seems that the lower the gauge, the longer it takes to glow. Just may be me though. I think it has to do with mass. Good luck and have fun!

Surface area plays almost as large of a role in heat up time as resistance.

Both your coils would produce the same wattage, but thermal dynamics is a completely different subject.

Even the space between the wraps of the coils will change the thermal dynamics.

what would be a ''good'' spacing between the wraps of a coil?

 

[Jazzi Mike]

2-3mm or so. The space between coils is often determined by the size of the RDA and the number of coils you are trying to wrap.

 

[dice57]

A lot is dependent on your coil design too. For instance my 2.5ohm 13wrap micro or nano coil will heat up much faster then my 1.8ohm 6 wrap genesis coil. With the micro coil being 1/16" or less in diameter, and wraps almost touching each other, I have almost instant vape. On a more traditional wrap with larger diameter wraps with wider gaps between wraps, there can be a 2-4 second delay before the coils are up to vape temp.

what will happen if the wires touch?

Depends ............

There is no one correct answer, for example if you are making a micro coil there should be none at all. I even pinch & heat my micros to make sure there is no space at all. The wire has to be oxidized if the coils are going to touch.

Sometimes trying to make an Inference about two things that are Very Similar can be Difficult to Conceptualize.

In the Cause you described, would it be Easier to think of One Wire being Very thin and a Foot Long. And the Other wire being Very Thick and an Inch Long?

 

[zoiDman]

It is the resistance the determines how fast they heat up so they should both heat up at the same rate.

So a Very Thick Short Wire heats up at the Same Rate as a Very Thin Long Wire when Both their Resistances are the Same?

there is too much to consider when vaping, ego..2.4 and go. I don't want to think that much!!
