JAC Vapour Series-B DNA 75w

[Bronze]

Use a spaced coil, not a contact coil. make sure that the coil is near room temp when the mod takes the first ohm reading. Set the maximum wattage on the mode just a little bit higher than you would use for power mode but not a lot higher. Start off with a low temp around 370F, you may not even get vapor much at that point and gradually increase temp until it is what you like.

If you are using a dna mode, you can use escribe software to change the increments for Temperature from the 10 degree default to either 1, 2, or 5 degree increments. Much more control of temp than 10 degrees at a pop.

My TC wattage is set 5 watts above what I used in power mode. Enough of an increase for improved ramp up time but not enough to blow my head off. Though there are days (like today) I wouldn't mind if my head blew off.

When you folks are talking about using the 'same' watts on TC as Power mode ... are you using the same type (SS, NiFe, ??) wire and ohms on both your 'Power' and 'TC' mod. I've only used Kanthal at about 1.5Ωs on 'Power' mods. So if I use SS at around .5 with TC, do I still start out around the same watts?

I use SS316 at around .5 ohm and set the wattage in TC to between 20 and 24W.

You need an appropriate wattage for the coil not what you used for 1.5 ohm coils.

One way to gauge what a good wattage range to try would be is check what steam engines says the coil you wrapped would be using. Or simply use the SS coil in wattage and figure out what works well for you in power mode and just up that a few watts.

Yes. Watts is watts regardless of wire type. Volts, amps, and ohms can float around all it wants but watts is the number vapers care most about in power mode.

Well there really isn't a lot of reason to switch style of vaping if you are happy with what you have.

TC can be finicky until you get it figured out with your specific equipment. I use it all the time because I can get a consistent vape and never worry about a burn hit. Even if the juice runs out it just throttles the wattage and nothing come out and no burnt wick. Generally better to lock ohm after you find it working well to avoid hiccups if it rereads the coil while it is hot.

I use SS coils in the .5 ohm range which seem to work very well as long as they are spaced coils. While the mods say they handle TC up to 1.5 ohms most of them. I don't think it actually works very well in any SS coil above 1 ohm and works better in the .7 ohm or below range with SS.

I don't use NI but it probably works better with TC than SS. But this would be even lower ohm. I have tried TI and while it works very well just don't like the idea of using Titanium.

SS is overall probably the reasonable choice because you can always run it in POWER mode if the TC doesn't work out for you.

Everything in this post mirrors my experience as well. as matter of fact, I haven't done a nickel build in my latest RTAs and it's time I did. I love nickel but there is a stigma about it, and I have to Chuck the coil with every wick, and if the mod decides to lose its mind I've got no wattage fallback.
When I decide to do simple, I use the 0.7 N2 coil in a Vika and put it on a stick battery.

i really can't use the Jac any more. i'm so sad.
it doesn't read the correct ohms on my tank. and the ohms jump around like crazy and then it flashes that my ohms are too high. my .5 ohm coil will read .63. i put the same tank on 5 other mods and they all read .53

i don' t know whats going on but it makes me uncomfortable using it. i double checked that the tc was off and it is. I'm not sure yet how to use TC as far as locking in the ohms so i havn't messed with that today.

i'm just sad.

Did you check the 510 pin well to make sure no liquid or dust? Maybe the pin is a little short on the tank. Do other tanks do the same thing on the Jac?

When vaping in power mode we mess around with our mod settings to achieve the same vape from puff to puff. But there are a few other variables that cause the vape to actually change from puff to puff. One of these variables is how long you hold down the fire button. That will impact the characteristic of the puff. Also, how warm was the coil when you began your puff? Was it stone cold? A little warm? Or have you been hot boxiing your mod and it's pretty hot to begin your puff. In our quest to have consistent puffs we compensate by toggling the fire button and/or how long a puff we take.

Bronzed One, I don't mess around with my mod settings. I MAY (very occasionally) turn up the heat, or turn it down a tad, but that's not a usual experience. I don't ever worry or think about how long I hold down the fire button. I take a hit, and with all my setups now, I'm extremely satisfied with each puff.

You are warped. Kat's not, but you are!

Oh, but she IS...

If you keep the same build as in wire guage, wraps, id, i would start out with the same wattage and increase or decrease as needed. If you built the same your wire mass would not change and only the ohms. hope that makes sense

it appears to only happen with my uwell tanks. both the original and the mini.
doesn't do it with the baby beast, or the NRG, (they are both on the same coil) but i don't really like the baby beast.

i just have no luck.

also a question, when you let go of the power button does the volts and amps disappear immediately? my other mods, the info will display long enough to read it. on the Jac only the ohms stay.



edit to add, the NRG coils are .4 ohms. reading at .44 and not bouncing around.

the uwell coils are both .5 on the Orginal and the mini (different type coils) and they bounce around in the .6's.

Same here. Normal for the JAC.

 

[Ladiekali]

ok, i think the Jac doesn't like .5 ohm coils.
my .4 uwell coil is doing fine.

is anyone else vaping .5 ohms on the Jac? curious if it's just my Jac or all jacs.

I vape 26 gauge, 316SS at .44 ohms. No problems here.

I'm using the 0.5 ohm Uwell Crown coils on my JAC. No problems at all. After a week or two the resistance reads 0.6 - 0.7 ohms. This is normal as the coil ages.

I'm using wattage mode. Not a fan of TC. I've used the 0.125 nickle coils in TC mode for the Crown, I just prefer the SS 0.5 ohm.

 

[Ladiekali]

my coils are fresh
what wattage are you at?
maybe it's because i'm going higher watts lately?
i've been pushing 50-60 on some of these newer subtle juices i just got.

up untill a couple days ago i was 38-42 watts max

I vape 30 - 40 watts.

 

[Ladiekali]

maybe the jac just doesn't like .6 ohm coils over 50 watts??

 

[Ladiekali]

ALSO wanted to say thanks about the TC info. i havn't done it yet... i been busy with other vape related nonsense. but I always wondered how to set temp with out knowing what temp you are using. i think i'll start at 370 and go from there. when you type, i read, even if i don't have a chance to respond i got kids and my puppy was just spayed yesterday, and this morning hubby left for deployment yes that's a happy face... cuz mama can play the nintendo switch for hours while chain vaping without interruptions!!

as Bronze says above. WATTS do indeed matter in TC, they can make or break it. You still need to set the Wattage somewhere close to what the coil would use in power mode or there will be too much throttling of the power and you will end up with mediocre vape for it. If you are using a coil that needs fast ramp you can set a ramp up wattage in most mods to handle that. But the main wattage should be in the area that the coil would use anyway.

Use a spaced coil, not a contact coil. make sure that the coil is near room temp when the mod takes the first ohm reading. Set the maximum wattage on the mode just a little bit higher than you would use for power mode but not a lot higher.

@Beamslider: Just wanted to extend kudos for your recent TC related posts. Your comments and tips are simply put, clear and on point.

I’d probably have to use at least twice as many words to say the same thing.
