I'm not sure where you get this from but it is completely wrong, I've never experienced any burning of the wick from preheat and preheat should not exceed the set temperature anyway. I use preheat set to 100w or 75w on the DNA75 and have it set at 6 which is the middle of the range.
A correctly built atomiser should give extremely stable temperature - as shown below

I have noticed that SS316 is less stable on the graph but the experience is fairly consistent

When setting up your new DNA device take the time to check all the settings and to download all the wire types you're likely to use on to your mod, ensuring you clean out any duplicate entries for material types (I get rid of the standard profiles and replace them with ones from Steam Engine), Once youve done that take time to ensure you've got each of the 8 vaping profiles set how you want them and once you're sure everything is the way you want it upload to the device and save it as a "Standard" mod profile (BTW I always save the profile that the device comes set with as "Default
modname profile".
Once you've done all that then providing you've built your atomiser correctly and connected it when cold then everything should work perfectly - time after time, day after day - I know I've vaped almost exclusively TC since the DNA40 came out, and have 5 DNA200's and 2 DNA75's...
