Yes... I absolutely agree with that... A coil with a wick running through the middle of it saturated in a liquid coolant with air running across the outside :) A stove burner, in your analogy, is not in contact with the liquid inside the pot. It will be much hotter. Try this... Pour the water on top of that flame. I have an idea of what would happen.

Again, not what is being measured. It's the average temperature of the stove burner.

BTW there is some FLIR stuff out there that shows normal kanthal coils reaching 700+ degrees in normal use.

I have a FLIR 420 thermal imaging camera, the next time I re-wick, I'll take some thermograms.

Don't really know what your point is. Bottom line is the idea that coils will plateau at the boiling temp of PG/VG is empirically wrong.

That's what I've been observing with the SXmini. No matter the atomizer or coil build, I am reaching a specific temp where it will stall. The thicker the juice I'm using the higher that temp has been. I don't have a FLIR camera, all I have is my ability to make observations. Perhaps your experience with the SXmini has been different, and I welcome your observations as well.

That said, you shouldn't discredit my observations just because you don't believe it. Would you like me to make a video for you so you can see what I am talking about, with several different atomizers?

I believe my conclusion is scientifically sound... The temperature at which a liquid changes state is not affected by how much heat you apply to it. Once it reaches that temp, while it remains in its liquid form it physically cannot rise in temperature without modifying the atmospheric pressure the liquid is being exposed to.

If the coil can get hotter, I'm certainly not seeing it reach any higher temps than where it plateaus, regardless of how many joules I throw at it. Throwing more joules will definitely make more vapor, but it doesn't have any effect on where the temp stalls out.

Like I said, if you're seeing different behavior, I'd love to hear your observations as well
 
are any of you new m class owners in possession of a device that has a crooked c-frame (the grey/black/pink part). I've heard this to be a problem and I'm seriously considering purchasing one on Monday but little things like this would bother me. i mean, so long as the chip works well ill be fine but i was just wondering

Mine is not perfect, but I didn't notice it until someone mentioned it here. Kind of like the buzzing sound. The grey part of the case is a little bit recessed on one side of the device, and sticks out a tiny bit on the other side. It's barely noticeable, and I wouldn't let it stop you from picking one up. It certainly doesn't seem to have any effect on the performance of the mod

Right, what I'm telling you is that is not because of a physical (as in physics-based) limitation. It is quite easy to "overpower" the coil and we have been doing it since the early days with nichrome and kanthal. The heat transfer from coil to wick is far, far, far from 100%.

You will also see different temperature curves for different coils. Or should, if things are working correctly.

I guess all of our experiences will be a little different because we all make our coils a little different, use different wicking materials, and use different juices.

I've done experimenting with my builds to try to get them to fire higher... For example, the build I am running right now on my Subtank Mini RBA, running the 70PG/30VG juice that's in there, plateaus at around 365F, according to the temp readout on the mod while firing. Even if I set the temp to 500F, it won't go past 365.

Maybe I'm doing something wrong? Could be... It vapes great...

Is that reached while vaping or without airflow across the coil?

What power setting are you on (soft, standard, powerful, powerful+)? Also, raise the Joules closer to 30J and you will hit that temp. I'm using 28g 3mm 6 wraps at .100ohm with my settings at 27J Powerful+ 420F. I'm hovering around 400-415F while I take a vape.

Let your mod sit till it's room temperature again and then reset the resistance and see what you get.

Hey thanx ;)

Yup... To the point where I'm comfortable with the vape anyway. For this build that is around 25J max. Anything more than that and it gets too warm for my tastes. Maybe that's where my issue is, I'm just running it at low Joules...

Sounds like it. If it's good for you then run with it. I have no clue what I am doing LOL. I have been all over the place with temps and joules trying to figure out what I like. Too many variables to play with :unsure:

Dam718,

Check this out it is proof of what you are saying:

Boiling water in a paper cup.

My SX Mini M class has the very low volume hum. It's a total non-issue for me if it is not something amiss in the electronics.

Jstrong,
I've been searching the web for several days and Im on the notify me when available list, on a couple sites, but haven't found any in stock. If you have a link to share, it'd be appreciated

Honest Vapor still has the Silver/Black and Silver/Grey in stock, YiHi SX Mini M Class. They are a highly reliable, long-established vendor with outstanding CS.

Using 70PG/30VG juice my ST Mini with Vapor Shark Ni200 coils reaches the 270° temperature limit I have set nearly instantly at 13 Joules. However, it's a noticeably warmer vape than my DNA 40 set at 13 watts/400° after refinement. :confused:
