Okay, so I have a Vapor flask DNA 40 on the way; very excited!
But I am just trying to educate myself about TP before it gets here. The main thing I am trying to wrap my head around the Wattage regulation in TP mode. I know (or at least I think I know!) that as the temp increases to the threshold set by the user, the wattage is bumped down to keep the temp within the boundaries of what's set. What I am wondering is; why wouldn't you then just leave the DNA 40 up at 40 watts, if all it's going to do is regulate it down? Is it because the temp will increase up to the threshold much quicker than if the wattage is set at a more reasonable setting? AFAIK the DNA "preheats" the coil by temporarily increasing the wattage anyway, so why not just set it high to begin with and let TP regulate it down when it's time?
Pardon my noobness; TP is totally new for me (as it is for most everyone), so I am just trying to get some info on it before it arrives. Thanks for any info you can give me!
You absolutely can. The only disadvantage to doing so is that if you have a build that can't sustain very high wattage then the flashing tp message might get annoying.
Basically here's the thing. There are those that run their temp set point much higher than the temp they actually want to vape at and crank the wattage down to achieve that. To me that just doesn't make a lot of sense as you're not taking full advantage of what tp mode can offer as well as introducing other possible issues.
The dna40 when it first fires ramps the wattage way above the set wattage to try to get the coil up to your tp setting. So if tp is way higher than you want to vape, you're going to get a hot "burst" at first. Then since the wattage won't sustain it, the temp is going to flux all over the place based on the draw. Draw a little faster and it cools down, slow the draw down and the temp starts to climb. Etc.
One of the great advantages the dna40 has to offer is a completely consistent vape from start to finish.
To do that you need to set the tp to the point where you want to vape at. Let's say I find that I really enjoy a certain juice in my orchid at 390 degrees. If I set tp to 450 and crank wattage down so it only maintains 390 during a draw then at first it tries to ramp up to 450, then it's going to be all over depending on my draw. The only advantage I'm getting from the dna40 is that it won't burn my wick.
On the other hand, if I set the tp for 390 and wattage above the level required to maintain that temp, then as soon as I hit the fire button it dumps high wattage in until it hits 390. Then it cuts wattage to maintain that temp. If I draw harder it applies more wattage, if I slow my draw down it cuts wattage. It will always maintain 390 degrees and keep the vape perfect and consistent no matter what.
I personally find the temp I want to run a build/juice at, then I set my wattage slightly higher than needed to maintain that temp. The best way to do that is to vape and see if the tp message shows up. If it does then decrease wattage a bit until it doesn't. Then if it shows up again I know my wicks are getting dry. But my vape is always exactly the same.
