Aspire Nautilus 2 flooded coil upon refill

[laurentiu]

Now i certainly know i have to read more.
I passed the two threads from before but i’ll also check the last study you gave me.
My concern is that i’m not that confident on my chemical/physics skills, and that’s somehow of saying that i don’t know nothing.
Anyway, i’m very satisfied that this is going to enlighten things up. I understand now that there are other topics about safe (at most as possible) vaping but i’m going to stick to NET’s. I must be sincere here, i didn’t dug this entire forum for (NET’s) safe vaping but if there’s no other thread about this, and especially sub-ohm MTL like mine is, it can be a thing.

Well, one of the biggest problems with most of the research is that they only used voltages. Most of the studies performed never mentioned watts, or temperatures of the coil or vapour produced.

And not one study looked at temperature controlled mods whatsoever.

That's just bad science, in my opinion.

 

[Grimwald]

With flooding, I often Vape it upside down for a few draws (yes, you will likely get liquid in your mouth). This burns off excess liquid but does not allow more to get into the wick.

You can also simulate the same thing by blowing thru the bottom airholes as you fire it (while upside down).

laurentiu, as Baditude has said. No problems with formaldehyde at those wattages.

It's not really about wattage, Mordecai. Formaldehyde (and other nasties) have been detected at very low wattages, mainly in 1st and 2nd generation devices, like the CE4.

New studies find carcinogens in vg and pg at high temps, even in tootle puffers

I'm just linking the thread because this subject was discussed here rather extensively and not without controversy. So please, don't shoot. I found it to be informative, but everybody is entitled to draw their own conclusions.

If you're really concerned about it though, look into TCR/TC/Temperature vaping for your next mod.

Agreed. It's really about the max temperature a coil reaches. So, newer devices, with more airflow and thicker (lower gauge) wires don't heat up as fast as those old-school ones, which used thin wires that tended to overheat rapidly, even at lower wattages. Generally, the idea is to keep a coil under 420-450 F or so. At least, that's what some studies suggest (including studies performed by Evolv ).

 

[Mordacai]

C4E is an ego style, things have moved on since then and also there was other devices on the market as well. Yet they were not tested and neither was different liquid compositions. But this is the way that can be science can be performed, first bias and then use statistics.

And did you read the Japanese research Punk In Drublic, if you have you would notice that some vaporizers at high voltages produced much less formaldehyde than cigarettes.

And in no way am I promoting vaping to be safe. Even cars aren't safe, yet people still use them and are allowed to use them.

I did read the majority of the article and acknowledged where they stated higher voltages resulted in 4 to 200x increase in formaldehyde, acetaldehyde, and acetone levels. Table 2 does chart 12 different test subjects with different levels of formaldehyde, acetaldehyde, and acetone but does not state what the operating voltages where. If this detail was within the footnotes and or references I did not bother clicking on those links. Although lacking details I do not dispute this claim.

The nautilus 2 is a flooder. Mine did. Screw the top back on slowly with your finger covering the opening of the driptip. This helps a little. But this is one tank i never liked much just for this reason

 

[laurentiu]

I've filled it twice since my last post and didn't got it flooded! Thanks guys!
Now i can't let it off cause it's soooo goood
Definitely the wattage has a strong point here.

That Japanese study is very clear. I think it will be very useful to know what brands are those which have the products that are not generating these nasty gases. How nice will it be if every product will have a label with all those ingredients measured in the same conditions?

Do anyone have the details of the 0.7 BVC coil. I mean, is there a way to know at which temp i'm vaping in different settings MOD works? If i got this right, keeping it at max 200C makes vaping quite safe.

Welcome and glad you joined.
Wattage:
I find that the wattage that works for me is usually a few watts over the lowest watt setting (where i can barely see the vape cloud on the exhale). Lower watt settings lessen the chance of burning the liquid/wick and generates my perceived best flavor.
After I get my Atty (coil and chamber heat up) going for awhile, I will often times turn the power down or up a few tenths of a watt or so to see if I can taste more flavor. I'm often surprised at how much better tasting the vape can be by adjusting the vape temp/wattage.

Hi
I don't understand. So for example this 0.7 which runs between 18 and 23 watts, you'll use at lower than 18 or somehow a little over 18?

You want to find the lowest watt setting in which you can see a thin vape cloud to start out. So you could start out at 14 watts and test for flavor. If not enough cloud or flavor or both, ramp up to 14.5 watts (16 or 17 watts ). The closer you get to ideal flavor/clouds the shorter the test increments. 14.,.7,.8 etc...... . Everyone's perfect setting differs with that individuals taste,equipment,flavor used, ambient temperature,etc.... . Their is no perfect same setting each time you vape, normally I'm around +/- 1 watt for my coil/device.

 

[laurentiu]

I see, so it’s a little lower. That’s what i’ve been doing in earlier but it resulted always in flooded coils.
Vapor and flavor are both good even at 14w but after a while it starts to gurgle cause it’s getting flooded.

 

[My Batt Hurts]

Agreeing with @BrotherBob - start lower and work your way up. Ideally, avoid going past the recommended limit for the coil. If you want to vape at 18 watts or above, keep the airflow open.

Did your kit come with another coil - perhaps a 1.8 ohm? It's a different, cooler vape and uses less power than the 0.7 ohm coil, but you could try it and see how it compares in terms of leaking & gurgling.

If you decide to try it, start with less power - say 8 or 9 watts, and slowly work up to ~12 watts if you wish. The recommended limit for the 1.8 ohm coil is 14 watts.

 

[laurentiu]

Yes, i have the 1.8 also, but when i installed it i was concerning more about the volts and how to keep it below 4. The 1.8 won’t perform good at 4 since is a 4.2-6 volts coil. I found it a little choky at 5.5 to 6 and removed it in the same day. It was 50/50 cause it was low in flavor/clouds and cause all that i read before was about toxins eliminated from vaping above 3.6-4 volts.
Now i understand that volts nor wattage are enough to check safety but temperature is and now i need to figure what temp can my kit generate on the different settings/coil i use.

I didn’t check the 1.6 and i think it works with N2 too. Probably i’ll buy one an see the results.

Again, I would forget about what the coil says about power, and set the watts where I get my ideal amount of clouds and taste.

 

[laurentiu]

So, does anyone know how can i calculate the (probably maximum) temperature my coil can go to?

Nope. You'll need a Temp Control mod and compatible TC coils to do that, and I'm not so sure how precise/accurate that would be.

I really believe you are over-thinking this formaldehyde thing.

 

[laurentiu]

Yeah, you’re probably right.
I think i understand now that it’s about temperature and i can’t control that either than feel it. So, i’ve let that apart for the moment.

Now i have another one
I had some 0 nicotine juice from Drake’s that came with a 20mg shot of nicotine salts. I’ve mixed them and now i can’t vape that thing. Inhaling is a little rush but exhaling it is really bad. I’m coughing every time. It’s very irritating. I’ve then added a half of freebase nicotine shot. Just a little improvement but still bad.
I’ve tested it with a new .7 coil and one 1.8 coil on my nautilus 2.
So, is there a special tank/configuration that should be used with nicotine salts, even it was added to a flavored base?

 

[Mordacai]

laurentiu, you don't necessarily need a special tank for Nicotine Salts. It seems as though the coil resistance just has to be high.

Also, did you know Drake's do concentrates that you can add to PG/VG base and Nicotine.
