RDA Help with Magma! - Ni200 build

[Spizzel]

Airflow is a big factor in keeping the temp limit in check. Obviously the more air you have passing around the coil will keep the coil cooler. I had a horrible time with my KFL+v2's hitting temp limit too fast, mainly because the airflow is really tight and wicking is not very good. The experience on my Lemo's has been terrific in comparison. The better the wicking and airflow is, the easier it is to stay under the temp limit. If you are using a tank system, then you should know it's limitations as far as watts go. The KFL+ for example has a wattage ceiling around 16 watts, anything more and you will be vaporizing more juice than it can supply. I can chain vape my Lemo's at 24watts/410F without issue.

As I said above, I tend to chain vape and as long as your atty has a good airflow and can keep up with the wicking (at the wattage you are using), chain vaping will not factor in to TP.

You can set the temp well above the flash point of your cotton without burning it, but as soon as your wicking falls behind either because it simply can't keep up or it runs dry, it will burn. That point varies with different types of cotton, but anything under 420F (some to 450F) and you should be able to burn it completely dry without any noticeable scorching. If you want a warmer vape than you can get from cotton without going over it's flash point, you may want to look into wicking materials that have a higher one.

Awesome thanks for answering my questions Randy, huge help. I know a lot of it was common sense but just getting the affirmation that I'm on the right track is great.

So it does seem though that I may be still having some issues though. The only way I can get my mod to fire more than say 6 seconds is I HAVE to set the temp to 450. I have a feeling though this may be due to my more restrictive air flow? I have been hearing people vaping at 410 degrees like champs though so that leads me to believe I still have some work to do. Even set at 420, with the rda top off to make sure it vapes after my builds I get TP pretty quick.

I have noticed that my gunk build up is a little lopsided on the coil too. It starts from the middle then has more build up towards the right. Is this an indicator that something is wrong on the side with little to no build up?

You shouldn't be hitting TP that quick at that low of wattage, you likely have a hot spot some where. You will get thicker vapor with higher wattage, but you can't do higher wattage unless you have the coil dialed in near perfectly. On the Magma it is pretty easy, just put a 2nd wire through the hole with the leg. Take a small piece of the 28g and put it through the side where the leg comes out, so it is flush on the side where the leg went it, lock it down tight and snip both wires.

Fire the coil dry with TP on and make sure the glow (which will be brief) is in the middle and not on a single wire or leg.

This is the current build on my Magma, 26g 12wraps .11 firing at 25watts/410F and only hit TP when I need to drip. I take 5/6 second drags.
