What a load o' shit.
1. Clean the coils, and you won"t be storing particulates. Round wire, flat wire, square wire; use what-the-fuck-ever shaped wire you fucking please.
2. Choose a gauge that fits your mod's capabilities, and provides the vape you desire. Some folks like to space their coils. Some don't. Try both ways, and see which you prefer.
3. Wrap coils at whatever diameter fits your atty, and gives you a good vape. 1mm or 10mm...if you got the space, the wire, and the amps, build whatever you damn well please.
4. Unless you're using titanium, feel free to dry burn new coils. You ain't hurtin' a god damned thing.
5. Starting 10W below recommended is fine. Increasing power in 0.1W increments will require 100 steps to get you to the recommended wattage. Time to change your batts.
1W increases are fine. 5W is fine too.
6. Set TC to whatever temp you bloody fucking like.
7. Nope. It means your chip is overheating because you either have a short, are pushing your mod too hard, are using shitty rewrapped 10A batts with bogus labels claiming "50A" & "5000mAh", or you're using a Wismec mod with a POS 510.
EDIT: Depending on the mod, it can also mean that the Temp you've set has been reached, and the mod is throttling the power to maintain that temp.
It DOES NOT mean the "atomizer nest-assembly(whatever the hell that is) is overheating".
8. Where the hell does that butt-nugget come from? Oh yeah, your butt.
There's no way for 99.9999% of vapors to monitor the temp of a coil. Only the Hohmtech FSK chip can perform TC on kanthol, and it's not even monitoring temperature. It's reading the rise in resistance of the wire as it heats.
FOH with that shit.
9. You can dip your coils in cat piss as long as you dry burn them after. I'd probably rinse with water too, though. 'Cause, you know, cat piss.
10. You almost had this one, but you had to get all parenthetical. Just don't pit oil on a fucking atty. PERIOD. Unless you've got some kinda ghetto-ass wrought-iron homemade shit, oil is completely unnecessary.
Those are my observations of your observations. Try not to take it too personally, as it seems you are kinda green, and I'm in a foul fucking mood. But that's some seriously stupid shit.
