Evolve DNA 40 clone temp control - first look :)

[Deleted]

In an optimised set up the DNA 40 should maintain the set wattage and not go above the set temperature throughout the whole length of draw.

If you set the correct wattage for a coil and get the wicking and airflow right, TP will only kick in when the wick is getting dry .

From John brandon: 'The only time you should be hitting a high temperature is if there’s something non-optimal about your system.'

Also remember the boiling point of juice is around 380-390f

The only probllem is we dont know how accurate the setting is, especially on the clones @scooby. I go with 450 for everything now.

Thanks robby, that's good to know.

I think that's the sensible way to treat it, the exact temp probably varies by atty, but setting to taste would still work well even if the base line is a bit off as the margins are so fine.  If your bored one day you could scorch test some dry cotton to see how close it is.

Maybe I can help a little.

Using virgin dry (never wet before) rayon on a authentic dna 40, set at 390F and 40w, you get a tiny streak of light brown on the wick. I wouldn't say scorched but rather "affected".

Obviously the rayon will never display any mark once wet even when you vape it till no vapor is produced, not even at 410F.

If you repeat my experience on a clone, you can judge pretty accurately if the settings are off and which way and work with that.

Hope this helps

Tony

My Ni200 and free Muji cotton came today from stealthvape, and fro practice i proceeded to single coil my magma,
NI200 32AWG 0.2mm Tempered
3mm coil diameter
12 wraps
ohms: 0.17
set temperature @ 430F with a set wattage of 18watts (not 24 as in the pic) which for me gives a warm vape without the temp protection kicking in too soon
I am astonished by the flavour from this single coil, just one question though, temp protection

I haven't read all through this thread robby so may have got the wrong end of the stick, but the point I was making was that so long as everything is optimised ie coil, power setting, wicking and airflow, TP won't kick in until the wick runs dry.

Example, I'm currently vaping at 17w set and a temp of 400c.  The temp at the end of a 5 second draw is 400-410c with no TP.
I've changed the temp to 500f and the result is exactly the same, temp reaches 400-410c no TP. There will be a difference if I came to the end of a tank though!
Edit: 17w maintained in both the above.

I know that we differ as to whether the device is variable temperature controlled, so the temperature that's set controls the power. Or a variable wattage device that has temperature protection. It makes a vast difference in the way one sees things, don't you think?

Just thinking out loud now, say you have 4 kettles,  2Kw, 4Kw, 6Kw and 8Kw all boiling and at 100c, none will go over that temperature unless it boils dry. (then they have thermal protection )
Supply enough cooling juice and air and the sky's the limit.

Basically, the way you wicked your setup allows the coil work at 17w while the wick provides enough juice to the system to keep it naturally at 17w. No problem there.

Problems might arise if you're powering your coil above the flow the wick can provide (hence drying out) and tc will kick in. That's the purpose of tc.

I can vape at 40w and 410F and the coil doesn't go over 400F because the wick can provide the juice... Another question that arises is... Do I want to vape at 40W? If I don't, I'll reduce the W and just vape at the setting I want. Once the tank hits empty, tc will go off anyway.

Exactly my point tchavei, mine is optimised for 17w. and yours for 40w, the temperature set is only there to protect from dry coils.

You will be getting much more vapor than me, and the kettle example shows why. The 8Kw will be producing vastly more vapour than the 2Kw but they all never go over 100c

[stax]

Can anyone tell me , please, where is the bottom of voltage protection of the clone? What voltage clone, if at all, says "weak battery"?
BTW after waiting FC to restock nearly a week I end up ordering from 3fvape the new model with USB port. Paid a Epacket to UK for £3 to speed up the delivery a bit.

If you  are getting 410 degrees your TP should be coming in at 400?

Not really a good anology, in "wicking" terms the kettle at 8kw (maybe a 1 ohm element) is 4 times better than the 2kw kettle (would be 4 ohms), for example the kettle will take four times as long to boil all the liquid in the 2kw kettle.

The point I was making in the original message was that we dont have reliable evidence that either the evolve or the clone are accurate in temperature accuracy. It has been posted elswhere that an Evolve chipset tested was 30 degrees out (tested on a thermal imager). I should point out also that my mindset has been based around almost totally dripper use. Even at 450 setting I get no burning of the wick whatsoever. After a couple of weeks getting used to the device it is clearly a normal mod until the wick gets dry. It really isn`t complicated at all. Temperature control/protection doesn`t do a thing until you reach the set point.

Have you got a link to the thermal imaging test you mentioned robby?
