Pretty good round up of points here ID…
… If you are not changing, or cleaning your coils often enough (can be even a daily chore if you are using juices that gunk badly), the crud can give a pretty harsh burn…
Especially rich tab's, dark, sweet and complex juices. Some may require changing organic wicks daily just to maintain flavor if they don't just stop the vape altogether.
The re-wicking also made me think about some of the problems I have had in the past with getting just the right amount of wick in a coil. Too much wicking and the wick became too tight and wouldn't allow the juice to flow quickly enough resulting in dry hits which were quite harsh…
Great observation on what often causes drying out the build, constriction. I call it
getting ahead of the vape. It can happen too with too wet a wick (if you apply too much power to clear it). Better to blow some air into the atty. The increased airflow velocity will speed up or enhance vaporization. Airflow and increased power must match.
To little wicking and it wouldn't give me good coil contact and/or vaporize too quickly drying out the wick and give me harsh dry hits and the occasional scorched wick. Yuck!
Also getting ahead of the vape. Think this is one of the most common problems as peep's seek cloud production and mistake this for
density (actual vaporization). Up to a point, getting as much media as possible in a wind (for that coil diameter) is a good thing. So long as it's not too much flow for the heat you should be able to graduate power up to that flow. With a variable, easy. But possible too with variations in wire gauge for a given diameter. And coil length, don't forget that. More turns require and deliver more energy to the wick. The greater the mass of the coil, the more wick needed. But too little media and you quickly overpower the wick producing more diffusion than actual vaporization. You go hot and dry, and quick!
…There is a chance you were just starving your dripper set-up and getting a harsh vape…
Just as hard as finding the right balance of wicking for a build is learning how much flow an atty can handle. I think squonkers make that a bit easier but it's still a learning curve. The point is you really don't want to flood but you prolly want to be as close to that as possible to keep all turns wet enough. Otherwise, a wet coil with a turn over-heating and the other possibility,
just plain straining the battery to reach vape temp, can be one of the harshest vapes there is. You'll run into it too if your batt drops to a voltage that's not enough for the build. Even regulated can push batt's this hard. If your vape's full and rich, vape on!
Great post ID. G'luck.
