Temperature Control SS316L coil

[Beamslider]

Okay, probably a dumb question but here goes anyway.

I'm using a Kanger subtank on a Pico 74W. I made a SS315L coil out of 30 awg wire that is 1.25 ohm.

I have locked the resistance on the pico and set it to SS temperature control. I have also set the wattage in SS to 12W and currently the temperature to 400F which seems to deliver a lot of taste and plenty of vapor.

The question, changing the wattage in SS TC anywhere from 9.5 to 12 W doesn't seem to change anything on output of vapor or taste. Changing the Temp does. So what is the point of setting wattage? Is it the starting W and then the mod changes it to maintain temp.

Basically is there any reason to change the W setting?

Ramp up time

The wattage setting in TC is the initial wattage spike ramp up power to reach the TC cap setting you have set, after the coil is at temp the mod will PWM (Pulse Width Modulate, this many milliseconds on this many millisecond off) to keep the coil at that set Temp. In just standard power wattage mode, the mod just fires at what wattage is set without the PWM and the coil continues to increase in temperature until power is shut off. So TC mode maintains a set temp of the wire to be consistent and sufficient to vaporize liquid to your liking, where standard power wattage mode is just like the Energizer Bunny, it just keeps going and going and going regardless of coil temp, wicking saturation, etc.

Not sure how well a 1.25 ohm coil is going to work for tc

Pico manual says 0.05 to 1.5 ohm Atomizer Resistance Range in TC. It is definitely working well from all appearance. Consistent so far.

Will be changing to .8 ohm or so soon. Have some 28awg stainless on the way.

I've done a 1.4ohm SS316L 30awg 2.5mm TC build at 8 watts and 430F just fine, though it is on a DNA75 control board no problem, just needed to be set to SS TC mode.

Like someone mentioned it mainly effects ramp up time.

With TC you can hypothetically just blast the power to get a quick ramp up and then throttle it at desired temperature once you reach it.

The other way is to use a normal wattage and just have the limiter in the background for the end of the vape / longer vapes.

TC is pretty flexible and has a lot of uses. I never did get my TC to work on pico that well though.

If you find yourself enjoying the TC mode and using it a lot, i'd suggest looking into getting a DNA mod at some point, you can get them reasonably cheap depending what you want.

 

[Beamslider]

Maybe got lucky but liking it so far. Consistently the same vape, prefer it to wattage so far.

Would consider a DNA at some point probably, but right now I have too many mods already.

Is Arctic Fox firmware better than the Pico Firmware?

 

[phirt]

The Arctic Fox firmware is good, but it doesn't change the actual chip behind it (obviously!)

The DNA chip is solid overall. Yihi is another high end chip for TC, as well as the FSK (hohmslice mods).
DNA is the easiest high end chip to obtain usually since a lot more mods use it over the others, so you can find them for reasonable prices.

If you do decide to get another mod at some point, consider trying out squonking at the same time. You can get a vt inbox for about $75, single battery dna squonker. (I'm a huge squonk fan right now!!)

Sounds like the logic is shutting down the coil. Raise the temp.

The wattage you set depends on the coil you are using. I set mine to 10W and 400F with a coil in the .8 ohm range. If the wattage is too high for the coil you are using the overtemp cutoff will kick in before you get a chance to vape it. 9.5w to 12W won't make a lot of difference, but the temp control will. If you raise the wattage, raise the TC setting.

The point of setting wattage is to get the coil up to temp fast enough without overheating the coil and making the temp control logic shut it down. I vape in TC at the same 10W that I vape at in power mode. You might want to check the TCR setting. SS is generally set at 92. My Alien came in set to 120 and the vape was hot. Dropping it to the normal 92 setting fixed it.

Used the coil in TC for 7 days. Thought it was tasting metallic starting today. So figured I would just change cotton. The cotton was still in great shape with no burn signs at all. Even though the juice is pretty clear it is sweetish and the coil was pretty much gunked over with the residue.

Tried cleaning the coil with a brush some but it didn't all come off. So ended up just making another coil and it didn't seem easy to get it cleaned up with the brush. Not a big deal wire is cheap.

I used to just burn it off with kanthal coils but I saw somewhere not to dry burn SS coils. Is that correct?

 

[phirt]

You are safe to dry burn ss just dont go hard. Keep it at 20w, get it glowing slightly, just enough to glow the outside a small amount.


Should be enough to clean them up nicely. You can wash it under a tap as well to help out. I do this on a old pen mod i dont use anymore. Obviously dont get your mod wet!

You can maintain your coils for ages this way. Once it starts not cleaning off like new i just chuck a new coil in.

 

[Kickingthesticks]

Shouldn't be a problem but that ramp up of 75 watts might be a bit to much for your small coil. You can change that to. I run artic Fox firmware on my Pico and it makes it easier to change settings and fine tune on computer.

 

[Beamslider]

Just changed over to arctic fox firmware this morning. Definitely much better than the stock firmware

 

[Carl2]

I've got the original Pico 75 W and also the newer Pico 25 mm 85 W version. The newer version has a lot more options in the menu that makes using SS much easier to use.

Evolv is THE king for temp control heck imo they're the king for everything. The 350j is solid but it's efficiency is what kills me. One 3500 (actually around 3300) 26650 last me 2.5 days (about 9-11ML) on the DNA 75. On the SX mini I go through around two lg hg2 batteries with the same kind of usage.

I've only used dna so was just going off feedback ive seen. unfortunately my 166 is in vape hospital! its definitely an awesome chip.

seems strange that you are seeing that big of a difference, are the cells all around the same use levels? would be really suprised that it is the board being the full cause for that but who knows!

other things i can think of would be a higher cutoff on the 350j or the hgs sagging more if your 26650 is a higher a battery. I easily get over 10mls out of 2500mah batteries on a inbox 75 as well.

what 26 batteries are you using out of curiosity?

Same usage, same tank, same coil, same power. It's just a very in-efficient board. I'm using some MXJO 26650 batteries, I use LG HG2 in my sx mini m class.

Could see a small portion of it being the pretty impressive drop off charts on those looking at moochs tests but no where near what you are saying. pretty big downside the board is that inefficient.

Ive picked up some ijoy 26650s for a mech squonker, looking forward to trying those out.

The batteries? They're capacity is pretty spot on (my VC4 calculates around 3200-3300 mah from 3.2 volts to 4.2). Drop off shouldn't matter, capacity is capacity. The only time drop off makes a difference is if you're pulling a lot of amps and pulls the voltage down.
