My Stealth Vape definitely needs cleaning, like most wires. Only wire I've so far seen that does not is Unkamen and random Chinese stuff from 3FVape (only checked 26G of each.) But I would still clean those too, just to be sure.
@icebat keep it simple to start. 8 wraps of 26G will work fine. Keep the legs as short as possible. Make sure they're as tight as possible under the screw heads. Do you have experience with Ni200 TC? If so, mostly everything that applies there applies here - make sure to lock your resistance (or press fire for the first time, on a DNA 40/200 (clone) when the atomizer/coil is completely cold.
I do not have experience with ni200, this will be my first time diving into temp control.
You can do contact coils with Titanium but keep it slightly spaced to start with, like with Ni200 (though you don't need to be quite as careful to have it absolutely perfectly spaced.)
When the coil is on there and resistance is locked, but before wick is in, hold down fire and confirm the coil doesn't glow or blow up. On a Yihi it should flash "DRY COIL", on a DNA 40/200 it will flash the TP messaage and should show it firing at very low watts. Other mods/clones will be similar.
Very good tips here, glad you told me this as I haven't seen or heard that mentioned before.
Then wick and vape as normal.
What TC mod(s) do you have? If it has a native Titanium mode, that's great. If not, you need a temperature offset. On any mod besides an authentic DNA 40, a range of 135°C - 160°C / 280 - 320°F should be tried first. On a DNA 40, the range is 155 - 185°C / 310°F - 365°F. If you have a DNA 40, check
this graph for the measured correct temp.
I actually don't have any temp control mods at the moment, but I'm planning on picking up an ipvd2 soon which does have a native titanium mode. Just trying to do all the research I can before I take the plunge. Thanks for those numbers though, as I've had my eye on a dna 40 mod for awhile.
If you want to verify your setting, you can always do a cotton burn test with a dry cotton wick in the coil.
Regarding wire type, if you want gauges other than 24 and 26 check out Crazy Wire:
GR1 (Grade 1) Titanium Wire They're also much cheaper per spool, however factoring in shipping to the US they might not be cheaper, depending on how many spools you buy. If you buy several they should be cheapest, especially if you buy five (and thus get the cheapest free.)
Or being in the US you could use Unkamen, whom I know have 26, 28, 30 and 32 gauge and probably 24 as well.
More great info here. Do you have a suggestion for wire size? Would I be best sticking with 28 like I'm used to?
All that should get you started. Most important thing is to build and try that first coil. Then we can help with any more specific questions and difficulties. Nothing beats experimentation.
