I've done a triple wrapped with 28G. Can't remember what it came in at, but it was an OK build that's straightforward to make. The nice thing about a SS coil of whatever complexity is if you lightly dry burn them when rewicking (mild orange glow not cherry red light up the room) they last months. I'm down to my adv builds lasting 3 months or so, my occasional use tanks just for a change in pace go even longer. I spend way more time wicking every week than the 5 minutes of mounting a new coil every few months.
Can You Explain Temp Control Vaping to an Old Fart ?

I've been playing with dual twisted 28ga SS, just to get a little more metal in there to bump up the heat capacity in smaller space, but my eleaf devices think I'm warmer than my taste buds do and they're throttling. Which makes me think either the TCR is different with twisted wire or the mods' TC logic is off. Or maybe my taste buds are wonky.
@PapawBrett you should set the initial wattage to or just below where you think it should be absent temperature control. If wattage is set significantly higher than the sweet spot, then the chip's logic makes it apply the full amount of power as soon as the resistance reads below the threshold. It's kinda like asking a jet engine to maintain to maintain a certain speed with only full throttle and idle for choices.
If wattage is set too low, the coil never reaches the set temperature.

Back again...
So I think I have finally read the directions enough to set up this little Pico (although I didn't really mind running in VW). I locked in my coil resistance, set my wattage and desired temperature...
and it doesn't regulate the temperature, it turns off power to the tank !
I was under the impression TC was a controlled limit - once you reach the limit the electronics prevents the coil from overheating. But instead it is a shut-off.
Have I got this right, or is this just a feature of the Pico ?
EDIT - 0.7 ohms, dropped from 11 to 10 watts, upped temp to 420. Still shutting off.

What do you mean by shutoff. The Pico actually turns the power off with no screen on?
If so that isn't right. Something very wrong.

If the wattage is too high, the Pico will flash a lot of protection on the screen resulting in a very lousy to no vape.
If the ohm reading is off by more than a few tenths, it will cause issues too. Make sure the coil is at room temp when first starting out. If you have another tank with a different coil, stick it on there hit the fire button take it off and return the tank you want to use. This will cause it to reread the ohm.

Is it off as in no vapor production when it's saying temp protect it is it the temp protect screen that you're concerned about? That screen in and of itself is not an error, it's telling you TC should be working. If the vape falls off that's another matter.
I'm not much for xplaining, but try this (what can it hurt)
don't lock your coil (for now)
set your TC Watts at 25w (to start)
set your TEMP to 250°, then climb to a happy temp limit
much truth in spaced coils for TC
just the way it goes about REGULATING is PWM (off/on-off/on)
TEMP PROTECTION just means it is working as it should (like a REV Limiter)

Now it appears to be firing as the "Temp Protection" flashes on and off. I have turned the wattage down further to 9W, not the vapor production I would want but it is acceptable...
Good that is working for you. But try a spaced coil. I get great vapor and taste out of spaced coils around .5 ohm in ss316 on a pico and other mods
What he said ^^. When it says temp protection it means you hit your temp and it backs off and holds it there. But it should continue to produce vapor.
That's what I thought it would do, but at whatever wattage you wanted.
Maybe once this kayfun is empty I will try a spaced coil (that will be fun, feeding cotton wicking through a spaced coil without pulling the coils together)
Same here. 0.5 Ohm SS316L spaced coil in my Serpent Mini. It's a winner and my 26-year old daughter covets the whole setup.
Pop, if you twist the section of wick tight just before it enters the coil it wont grab and drag on its way thru. Simply untwist it once it is placed where you want it.
That or I just cut my length of cotton of the pad, peel off the skin, fluff, and roll one end really tight. Pull it through to the center of the strip in the coil and cut to fluff and tuck the tails. The part I rolled tight is simply cut off and all I have left is happy fluffy cotton wicking.
Unfortunately, I have not tried the Pico and every mod goes about TC differently. The "temperature protection" on the screen although a poor choice of words is the mod doing it's job. The room temperature atty will increase in resistance as the amperage runs through it and when it gets up to the resistance that corresponds to your set temperature the mod will show that screen. When the resistance falls because the coil has cooled below the set point the mod should begin to fire again. The best mods will lower the voltage anticipating thresholds and provide an even sustained output. Theoretically, the power setting in TC mode should be the max power you want to make available and also perform as a function of ramp up time. Obviously 80 watts will heat a coil faster than 20 watts. Here's where my knowledge falls short. I don't know if the Pico works exactly that way. Again in theory, you should be able to set the power as high as you want and the mod will regulate it. Set the power to low and it will take a very long time or never reach the temperature set point. Sorry I have nothing definitive to assist you with other than theory.
