You will probably need to play with the power, temp and wire TCR value until you get it dialed in. The Drag is a little odd with it's TCR value and I think Anthony had to turn it up to 500F in his review.
Using a dripper is the easiest way to learn. Build a simple single coil, saturate the wick, vape till dry and the Drag should cut the power before the wick starts to burn. If the TC is not working properly you will get a dry hit, if the temp is too low it will cut power before the wick is dry.
If you are not getting a decent vape at all with a temp of 450F or higher it could be that the TCR value is too low and will need to be increased.
Also make sure the build vapes perfectly in power mode. It wouldn't be the first time trying to figure out why TC is hitting protection too soon, just to find out that there is a wicking problem and the coil isn't getting enough juice.![]()
I followed your advice and checked the TC on my Drag this morning. After rebuilding and juicing up the Wasp I vaped on it for several minutes. Eventually I noticed the amount of vapor starting to to drop off to almost nothing. Never did get a dry hit and when I removed the wick it was almost completely dry. Here's what it looked like
I'll have to remember to get some 0 nic juice the next time I decide to try out a mod's TC. Talk about nicotene overload!
