All my batts are 3.7v as I only use AW IMR so I purchased the new COV DCA 1.5 ohm, the Joye 1.5ohm & a 5 pack of the regular size 1.5ohm DC Cartomizers.... should be a good starting point I hope....
I love the DC 1.5 oHm cartos in my UFS. Tons of vapor and flavor at 6.4v. Not nearly as finicky as an atty can be, especially for the UFS newbie.
The following is the way I do things. (I'm describing me using a DC carto at 1.5 oHm and at 6.4v). You may do it differently and that's fine but if you're a UFS newbie give my method below a try because at least it's a starting point and from there; adapt, improvise, and overcome.
I would recommend this route for newbies. Go carto first.
- Pre-fill carto with juice, insert into UFS, close juice control by screwing counterclockwise like you were removing that part. It will stop though when it bottoms out against the carto, effectively closing that section off. Close air control by screwing clockwise until the control ring stops. You have now covered the air intake holes. Juice and air are now "turned off".
- I always work with the UFS unattached from my GGTS or other mod. I do it this way so when I'm ready to attach the UFS I can do a final inspection by looking for leaks.
- Assemble UFS to either GGTS or other mod, open air intake by unscrewing the air control ring. I open mine all the way. Open yours consistent with how stiff or loose you like your draw.
- Vape your head off and enjoy. Leave juice control turned off right now because if you open it prematurely, the juice has no where to go since the carto is full of juice and you will flood the UFS.
- When you start to get that dry carto taste, open the juice control and watch for bubbles. Open juice control a little bit at a time and dry vape (taking a vape but not hitting the fire button) until juice is fed into the carto. Sometimes a little turn goes a long way.
- If you have the air control wide open and the juice control wide open and are dry vaping and are not getting any juice into the carto most likely you have a vacuum lock issue. Simple to remedy.
- FIRSTLY, close down the juice control all the way then open up again slightly, maybe one half turn to start (as you are learning). Then remove mouthpiece, remove the new top cap, and unscrew the top tank cover about two times (revolutions) and look for bubbles. If no bubbles unscrew a few more times. Typically you'll see bubbles now. Close top tank cover, re-seat new top cap and mouthpiece then try to dry vape. You should be OK now as you've broken the vacuum effect inside the tank and the juice can now flow.
- The reason I said to close the juice control and then open slightly is because if you left it open it will have let in too much juice and the UFS will have a heavy gurgling sound when you vape on it. This is the sound of a flooded UFS. Don't worry, alternate between dry vaping and hitting the fire button as you vape and you'll pull that extra juice into the carto and it will be vaped up. I've had a lot of success in this method.
You can practice your juice control this way until you have an understanding of the "mechanics" involved. Cartos are more forgiving if you open the juice control too much as you can dry vape the juice into the carto (and thusly into the carto batting) and then when the gurgling is (mostly) gone, fire away and vape.
Remember that all cartos and attys are different and you most likely will have to manipulate what I've said to suit your vaping style and even your altitude.
