I think i keep burning my wick, please help.

I believe it may be due to the liquid getting thicker.
You'll notice that on a fresh tank of liquid, the liquid is thinner and wicks more easily. When you're near the bottom third of the liquid, you'll find that it has become thicker and slushier, hence the wicking issue after some time .

1) use juices with higher pg content
2) add pg when you have the problem.
3) use cotton as flavour wicks.

Try each solution one by one and see which is best for you.

Lowering your wattage IS lowering your voltage. So that's good on both fronts.

You could try adding a couple of drops of water to a small bottle of juice (you saved an empty bottle, right? ) and shake well. This will help thin the juice slightly, help it to wick, and also help cool the vape.

BTW...I have mentioned removing flavor wicks to people if I thought the wicks were being choked off in a Vivi Nova, for example (user made coil). However in your case, I'd guess it's the wattage.

Watts used vary a bit by device too. So there's no fixed rule, although I consider 8 watts on standard coils to be more than sufficient 90% of the time and over that it gets iffy. Fruit flavors and some others often burn at wattages that are fine for other juices too so it also varies by juice.

Okay 3-5 second pulls are fine, just wait the same between pulls.

You mat want to thin that lot of juice with some PG, water, vodka or, everclear, whichever you prefer and, next time try the flavor in an 80/20 blend, it should do better.

PG = max flavor, thinnest, easiest to wick, least cleaning needed, least vapor, more throat hit.
VG = milder flavor, sweeter, thicker, harder to wick, more cleaning, more vapor, less throat hit.

I'm in agreement with the suggestion to lower the watts/volts.

I found that I couldn't go over 4.2v on the Protank without burning taste.

I use 100%Vg and my liquid is thick.

Thank you everyone, these suggestions should prove helpful. Im sure ill get it figured out soon

Just to clarify, you're not actually burning your coil even though that's the generally accepted term. What's happening is carbon buildup on the coil and the wick. That's the black stuff you see on a dirty coil.

For the coil, it insulates the metal and interferes with heat transfer to the liquid. For the wick, it hampers the wicking ability of the silica since the carbon coated portions don't wick very well if at all. For bottom coils, you can also get leaking since the liquid will just roll off of the carbon coated portions instead of sticking to the wick.

And this problem escalates pretty rapidly since the end result is that you tend to fire longer since:

- the heat transfer is inhibited so you need more power to burn the liquid
- there's not as much liquid being wicked up to the coil so you take longer drags to get more vapor

A good cleaning will extend the life of your coil but only up to a certain point. For me, Protank coils only last about 4 days before the vapor production starts to degrade. A clean and dry burn can stretch that up to a week, and at that point I just build a new coil.

I hope I don't offend anyone by saying this, but the voltage should not be the problem here. If you read op's post, he gets the problem only after vaping about 3ml or 2 days. If voltage is too high, he would know it in the first few vapes.
If liquid is too thick in the beginning, wicking problems should be noticeable in the first few vapes too.
Hence, the problem should be occurring near the last ml. But I'm assuming op didn't top up the juice.

Therefore, it should be the juice getting slushy/thicker near the end, which is natural.

Besides the suggestions I gave in my earlier post, you can also lower voltage when you encounter this problem, but at the expense of flavour, vapour and throat hit.

That's true, juice is also a factor. Dark juices destroy my Protank heads unless I do a daily clean and even then I can barely get 5 days out of the heads. I've switched to using top coil clearomizers exclusively for these darker juices.

Very well said. Totally agree.

I've had some of the same issues with burning tastes with some of my juices. I have multiple different flavored juices and always at about the same pg/vg ratio. I've found that some flavors taste burnt and others of the same pg/vg ratio don't at the same voltage. I've learned to just just the voltage on each juice til it tastes good to me.

^^^ This.

So A) Get less-gunky juice or B) clean a lot. Like mentioned above, darker usually = gunkier jucie and more VG = gunkier.
