I see a ton of threads and posts around the web with people having issues with their TC mods. I want to address some of these things here. This isn't an end all be all guide to TC, more of a post with FAQ's
I've seen, more than once, people having issues with their mod firing TC coils. This can be attributed to a number of things, but usually it's caused by a few common problems. The first is the ohms of the coil are to low. This causes a mod to fall to fire. The average mod out there can only fire a TC coil with a resistance of .08 or higher. (the Sigelei Fuchai, and some others, can fire as low as .05) This is what brings about questions like "My 5 wrap 22g nickel dual coil build doesn't work. Why won't it fire?" Well it's because in order to meet the .05 ohm threshold, the coil would need to have 25 wraps with an inner diameter of 3mm. That would be a huge coil! Also, that doesn't take into account that the coils need to be spaced, not compressed, making the coil even longer.
This brings me to my second point. Compressed vs. spaced coils. TC coils NEED to be spaced, any contact will cause the coil to short and throw off the resistance as well as make the coil heat unevenly.
TC coils CAN last longer than kanthal, but there are a few things needed to ensure this is true. When re-wicking a kanthal coil it's pretty common tip dry fire the coil until it's red hot, then dip the coils in water to clear the gunk. You should NEVER do this with nickel. It's much more effective to brush the gunk of the coils gently. Dry burning nickel can be toxic in extreme situations, and if that's not enough it also weakens the wire causing it to not lady as long.
One of the most alarming questions I see asked are coming from people who are excited that they just picked up their first TC coil heads or they just built their first coil with TC compatible wire. It usually goes something like this, "I just got my TC coils, but I don't see what's so great about them, my mech mod worked way better when I used regular kanthal. What the problem?" This is alarming because firing a TC coil on anything other than a TC mod is unsafe. When TC coils, nickel specifically, is heated beyond a certain point it releases harmful gases that are absolutely unhealthy to inhale. So please, only use your TC coils on a TC mod.
