RDTA Cotton.

[Benjamin899]

afternoon all,

Made the jump to an RDTA, Geekvape peerless. Flavour is amazing and I should of got one ages ago.

My question is and forgive me if it’s a bit of a noob question.

When burning off the e juice like when you swap out flavours how come the cotton doesn’t burn like traditional tanks?

I see loads of people mention when changing flavours just burn off the juice, which I do no issue but for me wondering why it doesn’t burn and destroy the cotton like a normal coil would?

Thanks

Um, if you are talking about letting a saturated wick "burn off" most of the liquid, well, I'd imagine for most people they stop the process as the vapor production eases off, if you kept "dry burning" it, the wick probably WOULD burn eventually.

It's a method to remove most of the eliquid from the wick, not every last molecule etc., or at that point, you would in fact be setting your wick on fire.

I use a rayon wick and have also heard of the method of "rinsing" one's wick with distilled water. I have indeed tried that and it works equally as well. Not sure how cotton would fare with that method, but rayon does pretty well. Etc.

is the tank empty? if trying a flavor/switching, i dry burn with wick absent, then re-wick

Same here! I buy cotton pads and cut it up into several strips for wicks, so it only takes a second to put a new one one. I get about 7 wicks out of one pad.

You using TC maybe?

anna Pretty much summed up what I was getting at.

Removing the juice without burning the cotton, just wondered why can be done with rdas and not so with a normal tank.

Normal either burn or just taste horrible when switching

They can’t. I think something else is going on. Hence the question about TC

The point I was making is you see a lot of people on YouTube and such when you hange flavour on a rda just firing to remove excess flavour before changing, so I was asking why this doesn’t burn the cotton like if you just vape a normal tank when empty.

Because you don't actually vape it dry (unless you are using TC, then you can kind of do it because the coil's temp will be monitored and if it exceeds "burning" (I'd assume whether the tank is connected or not, although I don't know how that might change things w/r/t the coil) well, if you are using TC you can pretty much vape your cotton dry (without any access to the build even) and then change flavors (just refill).

If you are doing the "top off" vape dry method with or without TC, I'd imagine you'd have to stop before ALL moisture is gone from the cotton. So, you could get some, and possibly enough to make some difference, but I'm not sure I'd hold my breath on it. I don't use cotton either, so there's that.

It will, if you overdo it. I think most of the time, what they do is they remove the cotton and just fire the bare coil to burn off any gunk that has built-up since last cleaning. This is usually followed by a rinse and/or scrub, then another dry fire, and finally, a fresh bit of new cotton. If you dry-fire a coil with cotton in, then unless you're using TC (temperature control), you're likely going to burn it. Unless you're watching old old videos, with silica wicks? That stuff don't burn. You can dry fire the heck out of a silica wick. Which is a good thing because, I hear, they don't transport juice to the coil well at all and are extremely prone to dry hits because of this. Probably just stick with cotton (or rayon, same thing basically) and change wicks often.

Re wicking isnt that big of a deal for me. I would never dry burn a coil with a wick in. If youre changing flavors, remove the wick, take rdta apart and rinse everything off really well in hot water. Rinse out as much of the old flavor that you can and then dry everything and put it back together. Re wick and there ya go. Which reminds me, its time to clean out my limitless plus.

Don't worry about it Benjamin, we were all noobs once too

OK, so you're leaving the wicking in the coils and burning off some of the juice. I use wattage mode always lately and do that sometimes too when I want to change to a new flavor and don't need to get all the old juice out first. If I want to get rid of all the old juice I remove the wicks, dry burn the coils and re-wick.

If you're in wattage mode on the mod, once the wicks dry out to the point that the coil temperatures get hot enough to burn juice, well it's going to burn juice. It doesn't matter what atty you're working with, there is no way around this issue.

If you're not burning juice the wicks are still too wet to allow the coil temps to go up too high at the watts you have set. There is no mystery here, it just is what it is.

If you're running in temperature control mode instead of wattage mode, and TC is set up cool enough (TC accuracy counts big time here) so your wicks don't burn when they dry out, you can get rid of almost all the juice on them without burning a wick because the TC will lower the watts to keep the wicks from burning.
