Green flame.... should I be worried?

[painkiller0007]

So I'm about 3 months into full on vaping. I have been rebuilding the protank 2 head now for about a month and tonight I had an odd taste in one of my tanks. So I broke it down pulled my organic cotton out and dry burned.....this is where I noticed the green flame. When dry burning the coil I was getting a green flame and if I'm not mistaken that means there is copper in the wire rite?
It is 28guage kanthal from lightning vapes I bought on amazon. I'm using a vamo v5 with stacked 18350's. 9 wrap micro getting a solid 1.2 ohm reading on the vamo. vaping at around 10-12 watts and this tank has been using Mt baker vapor menthol 12mg 50/50 blend.
Any advice on this?

Just noticed it was getting hot near the head base/coil so I checked to see what mode I was in.....at some point in time I went back to mean mode. I just switched back to RMS

I'll keep my mouth shut on certain opinions I have.
I think your way to low on the OHMS for the mod your using and need to get it up to around 1.8 +. I've used some micro coils that were as low a 0.3 ohms, on a Reo Grand. If I ever see a flame on anything, I'll tear it apart and do it again. YMMV, and this is just my

How hot were you running it when you dry burned? You may have just set off a fire burning the crud that was built up on your coil.

No need to keep your mouth closed I asked for help/opinions. Lets hear what you have to say. Why would I want to go up to a 1.8 coil vs a 1.2 coil?

Pretty hot. I did notice the coils were heating up fast but I'm guessing its from being in mean mode.

I'll give you my unfiltered opinion. I think that's probably too much power for your typical kanger style coil, and too low resistance also. But, hey, if it tastes good...no worries, what do we know anyway? I generally vape much lower than that on my Kanger coils...usually in the 5-8W range with a 1.8 (and sometimes higher) ohm coil.

I wouldn't be inclined to think it's copper, it's probably just the gunk burning off. Sometimes you can see a little fire from a dry burn, it's rare but it does happen on some juices. Maybe you didn't completely clear the cotton, too...which could produce a little bit of fire, too. I wouldn't worry about it too much, myself. Just reload and vape on!

Awesome that's the kind of answer I was looking for. I'll try hitting lower watts and see how that goes. That's for the advice.

Going up in your resistance will give a lot more options in your adjustment. IMHO.

I do try to wrap mine to about 1.5 ohms, but I accidentally forgot a few wraps once and made a very beautiful, fully functional, .9 ohm coil once and went with it. I just tried to make sure not to blast it with too much power and it worked great. I never saw flames, but I did have to change my wick more often. Makes me wonder if you have some contaminant in your juice or coil wire.

 

[painkiller0007]

It seems I don't get that effect while in RMS mode. And it was only with the one coil. Here's a video of a working one I made.

E-liquid is flammable and might ignite when dry burning, not a big deal, just blow it out. I don't know if it is suppose to be green though, never noticed the color of the flame.

Imho the resistance of your atty does not matter at all as long as your vamo allows to fire it. At 1.2 ohms, you are close to the limit.

10 watts is fine if you ask me as long as it wicks properly and that it does not burn through the rubber insulator.

Doubt this is your problem and I hope it isn't just some info on stacking batteries Just info thats all. YMMV

I will ask why you would want to stack batteries? What do you wish to gain?

Nearly all battery experts always caution NOT to stack batteries:


"Stacked or unstacked? In some devices, you can fit two 18350’s when the device is configured for an 18650. This boosts the voltage output from 3.6V to 7.2V which means more vapor. Yay. BUT, you should never do this... ever. Unless you are familiar with matching batteries, you are only endangering yourself and others.

You may think, “Well, shucks, laptops have multiple batteries in them, why can’t my ecig?” Laptop batteries are specifically designed for stacking and are paired for use at the factory. When using unmatched batteries, they will discharge and provide current at different rates. This means one battery will continuously take more of the stress than the other.

You may not notice any trouble at the start, but as the batteries age the problem will become more severe. Push the batteries a bit further and now you’ve entered the realm of thermal runaway. Downside being that one battery entering thermal runaway will push the other battery into thermal runaway. Now you have two small, flaming explosives only inches from your face. Save your teeth, don’t stack batteries."

If you decide to ignore the above warning, do NOT ignore the following tips:
Never stack an old and new battery together
Never use a damaged battery
Test your batteries after charge to make sure they aren’t overcharged
Test your batteries after charge and then a rest for a couple days. Make sure they are holding the charge.

Sometimes, just because you can, doesn't mean you should. There are ECF members who do stack batteries, but they either ignore the risk or are super diligent in the methodology required to do this with some relative safety.

I've encountered flame frequently when dry burning coils, and not once have I seen a green flame. I don't want to worry you, but that doesn't sound normal, and your initial assumption of some type of metal seems very reasonable.

Copper will burn green, and I believe brass will as well. Is the 510 threading on your vamo brass? I know it's brass on the gunmetal ones, I've heard the 510 portion is brass even on the stainless version but I'm not certain. The protank's base (with 510 connection) is plated brass too, right?

This is actually something that's made me paranoid for a long time on 510-fed air systems. When you screw your atty on and off the device, you will grind down some of the metal into a fine dust. When sucking air through the 510 connection, you are going to suck this dust up into your atty.

I suspect that small amounts of brass dust are getting sucked up into the protank and coloring the flame green. There really is no other explanation, other than some ingredient in your liquid burning green. That would be easy to figure out, burn some of your juice, if it burns orange you know that's not the culprit. I suspect it isn't though, never seen coils or liquid burn green before.

I have seen the green flame when torch-cleaning my braided ceramic wicks. However, when I do this, the green flame comes off only from the locations on the wick where there are crusty burned juice bits, or from the wick's freshly snipped ends (dirty cutters) or from the sections that my unsterilized fingers have lingered upon. I am thus inclined to believe that this is simply oils and solids burning off -- perhaps containing some metals -- and not necessarily continual toxic contamination.

I guess the question then becomes: If after you see the green flame, does it eventually go away and not return once your coils are clean?

 

[Dampmaskin]

The percieved color of a flame depends on lighting, and on the color of whatever is in the background.

And copper is not the only thing that burns green. Here is an article about it: Why Are There Blue and Green Flames?

 

[NonCorp]

Sounds to me like you ignited the rubber grommet that is part of the coil head assembly. Way too low hms for a protank, unless you're really sparing on the power you're putting in, you are bound to melt the rubber grommet. Don't know about you, but I wouldn't want to vape melting rubber!

 

[painkiller0007]

Not sure what it was and I never could recreate it. If it ever happens again I will try and snap a picture of it.
