Temperature Control Question (iStick 60W TC)

[falcor]

I recently got an iStick 60TC, because I liked the form factor, and partially because my previous MOD (a Cool Fire IV) doesn't have TC.

I also got eLeaf's MELO 2 atomizer tank, and some TI 0.5ohm coils. My other tank is an Aspire Atlantis 2.

I've been interested in TC for a while but still haven't figured it all out yet. I know TI coils are meant to only run in TC mode, I think. But what I can't figure out is the temperature setting relative to wattage.

That is, the iStick 60TC allows you to set the wattage when in TI TC mode. It defaulted to the full 60W. I tried running it at 45W with the same temperature setting, and got a cooler vape. Maybe that is to be expected, but I don't understand, is it all just relative? Shouldn't temperature of the vape be the same when the temperature setting is the same (e.g., 400F, 450F, whatever)?

Or is it all relative? In the end what is the best setting of watts while in TI TC mode, and what settings does the average vaper vape at?

By the way, does anyone have thoughts on the MELO 2 vs. the Atlantis 2? I got the MELO 2 for the TI coils, but then realized they work in the Atlantis 2. The MELO seems quite a bit airflow-constricted, but is easier to refill than the Atlantis, which requires taking apart.

I'm also curious about whether there's a difference in the TI coils vs the standard stainless steel Atlantis coils, other than temperature control. Titanium vs. SS when TC is taken out of the equation.

The watts you set basically just control how fast your coil reaches your desired temperature. Higher watts will make it ramp up quicker, lower make it slower. I kept mine set around 50 watts. I liked for it to hit temp protection after about 2-3 seconds. Also, make sure you lock the resistance of the coil while it is at room temperature. That is very important for TC to work properly.

I can't compare the Melo 2 to the Atlantis 2. I did use some of the Atlantis coils in the Melo 2. I noticed they had bigger juice flow holes, but worked about the same in my opinion.

I haven't used stainless steel yet, but a lot of people say it gives a cleaner taste. You won't be able to use TC mode with stainless on the TC60W, but you can run stainless in wattage mode.

Thanks for the info. Regarding locking the resistance, why do you do that?

It seems like to me, since room temp is going to fluctuate depending on where you are, you would want it to be dynamic and adjust itself. Is that not right?

BTW, the first TI coil I put in the MELO is a 0.5ohm coil but reads at 0.62ohm on the screen. Does that just mean the coil wasn't manufactured very well?

Temperature Control works based because the resistance of metal increases with heat. Some metals, such as titanium, have consistent and predictable rate at which the resistance will increase. This is called the Temperature Coefficient of Resistance (TCR). The mod will actively monitor the resistance of the coil while firing and adjusting the watts accordingly to achieve the desired temperature. By locking the resistance of a coil at room temperature, you are providing a baseline for the mod to compare to.

It's normal for coils to not read the exact ohms they are supposed to be. You could try cleaning your 510 connections and the base of the coil and tank, where they make contact if you want.
