RDA Massive throat hit, no vapor

[GoBlue88]

Hi all,

I'm new to RDAs and having trouble getting up and fully operational on a consistent basis. Generally, when I rewet the wick I'll have to take 4-5 drags that produce massive throat hit (making me hack).

After a few of those, I start to get nice clouds with a desirable level of TH. Is this a common issue, and does anybody have any solution?

The coil build was done with assistance at a vape shop with what they called a "cloud" wicking. It's a single coil with the Cotten coming out of either side of the coil then resting under the coil.

Thanks in advance for any advice

When you first wet the wick there is a lot of ejuice on there and a large amount of throat hit will be given.

after you burn some of it off with your first 3 hits it will become weaker and the throat hit will be

more desirable.

Sure, but shouldnt that massive throat hit come with massive vapor? Why is there little vapor production along with the undesirable harsh TH?

Is the cotton touching underneath the coils? That much wick contact, especially if the drip well is full, will likely be your culprit if that's the case. I try to keep my coils clear of any wicking from all angles.

the solution would be to get used to the right amount of juice to drip at any one time.

sometimes if too much juice is on the coil it becomes Flooded and it can slow down the amount of vapor

that you will get.

I agree with both of those and it may provide a solution, but it still doesn't justify why the throat hit is occurring without the vapor. I appreciating the solution seeking but I would also like to understand why that is occurring and how it is possible. The vapor is carrying the nicotine, which is causing the TH. So how is TH happening at an elevated rate with very little vapor, whereas when vapor production increases TH decreases?

By "keeping your coils clear of wicking" do you mean keeping the coils from direct contact with ejuice that ISN'T on the cotton wick? So avoiding the coil from touching still ejuice in the bottom of the well?

Right, if your coils are sitting in your juice or if your wick is stuffed under the coils and making contact, that's the issue. Like trucker said, it's the dripper equivalent to flooding.

As for the reasons behind the TH and lack of vapour, keep in mind that it's heat that vaporizes the fluid, but airflow that produces volume. If your coil is being stifled you're essentially vaping a concentrate.

sometimes you can get a big shot of throat hit and see little vapor with it.

The nature of this type of atomizer ---I drip too-----has sometimes a host of unexplained things

sometimes. I have had lots of vapor and no hit and vice versa. A lot of chemistry and science and

air flow and amount of cotton and type of cotton and type of juice vg and pg and amounts.

many things affect this thing called vaping

So the comment about coils not touching free ejuice makes sense (perhaps it's spitting ejuice itself into my throat?)

But I can't see understand your "concentrated" theory. Say it does produce more concentrated vapor, then shouldn't I just get a more sense dog causing my excessive throat hit? The only way that make sense is if the nic is burning off and the PG/VG are not at this point of contact.

It can also happen if your airflow is simply aligned poorly. I've experienced this with my Pulse dripper, which doesn't have airflow control per se, but more like selectable airflow. If I accidentally set the thing to the wrong hole(s) for the coil(s) I get a really rough draw with next to no vapour.

 

[thetrucker]

with experience you will start to be able to tell what you will get from your atomizer and even then

sometimes it will surprise you with ejuice going fast and slower and one day it will work like a million

dollars and with out doing anything different the very next day it will be funky.

 

[GoBlue88]

Also this is a Sapor "top airflow" (air holes near the top of the sidewalls) if that makes any difference

I've definitely noticed its a fickle hobby/habit

I'm glad I'm not alone with the harsh hit/low vapor phenomenon, but it seems very strange to me. The only thing that really makes sense to me is getting actual unvaporized ejuice kicked to the back of the throat by the issue you mentioned (coils directly contacting juice in the well).

My Pulse is a top airflow design as well. Top air designs have the benefits of being very leak resistant, but overconfidence can have you overdripping very easily.

Think of a low smoldering fire. It's still hot, still burning, but you may need to make some space to let the air get to it.

 

[thetrucker]

yes this thing is very tempermental and sometimes if my tank sets in a warm car the juice will get very thin and

it will leak past the wicks and run out the airholes...even though it was working fine when it was left it the car.

it is something you have to play and fiddle with ...sometimes it is very unpredictable.

That makes sense. I think I'm going to try and lift the coil to ensure no contact between the coil and ejuice in the well. Thanks for the help fellas, I'll follow up if I'm still having issues after some modifications.

I think of this vaping as a pot of boiling eggs as it is constantly changing-----wicks are getting dry or getting wet---wicks

are getting gunked up and vapor production is changing----ejuice is working around oxygen and getting steeped--more and

more and getting stale as time progresses---your taste buds are getting bombarded with the same flavor and you stop

tasteing the ejuice----my menthol tastes weaker and weaker as I keep using out of the bottle.

you hit the fire button often and then maybe less often---long drags and the wicks get the ejuice all vaporized

in a hurry-----next time the drag is shorter and wicks get a chance to gather more juice before you hit it again

and they can keep up with you a little easier on tanks.

voltage on a mech mod is constantly dropping as the battery goes flat which changes the vape.
