temp control really that good?

[coilburner]

Whats up Ohmies, . I just picked up my first temp control mod yesterday and I have found temp more to be more useful to tune the flavor of your vape more than anything else. Depending on the air flow and the temp setting you can really get the most out of your juices without burning the cotton. Its awesome, I love it.

i had my doubts about TC-not being a dripper or using rbas and/or rdas inever had a dry hit with the many tanks and coils i used in the past. so you never get a dry hit with TC, big deal, i never had one before anyway. being curious and a compulsive gear buyer i bought a TC mod to try and see what the talk was about..well, i am a total convert to TC for one simple reason-the ni200 coils taste so much better than the kanthal coils- i never knew there would be such a difference!i just thought i was enjoying my vaping with the old coils until i tried my favorite juices on the new ni200 coils-no more metallic taste and just a pure, smooth vape through the entire tank. to me, TC is worth it for the difference in flavor alone. any other benefit is just icing on the cake. as soon as i experienced vaping with an ni200 coil i knew i would never go back to the kanthal coils i had been using and thought i was enjoying- TC has shown me what great flavor and great vaping is really all about and, of course, YMMV.......

....try titanium.

 

[peterforpats]

how does ti differ from ni as far as flavor goes? i know it is all subjective but specifically what makes it better than ni IYHO? thanks....

 

[Ardy]

I still get a slight metallic taste with nickel that I don't get with Ti.

Better taste, firmer wire to work with, can be re-wicked without deforming.

I've read through this, and there's much being missed about TC, at least where the Evolv product is concerned;

When you use Kanth and non a TC chip, and you set the device to 25 watts, it fires at 25 watts period, no matter how cold or hot the coil is;

With an Evolv TC chip and NI or Titanium wire, there's a pre-heat phase that powers the device to its limit (40watts in the DNA40 and settable parameters in the DNA200) until the wire nears the set temperature, so your vaping at your desired temperature much quicker and then at constant level.

You can't come close to that capability without it.

the first reason counts but the last two don't matter to me-i only use pre-built coils .so far, there is a lack of ti prebuilt coils so my only choice is the ni200 coils which are readily available. until they make ti coils i will just have to get by with the ni200 coils. luckily , they taste so much better than the kanthal coils. the evic vt has ti coils but i haven't ordered any betond the single coil that came with the device- i didn't notice enough of a difference in taste to order more ti coils- the ni coils taste just fine for me and those are what i am using. i appreciate the opinion that ti tastes better but i don't get that so the ni remains good enough for me. if and when they come out with ti coils for the subtank or atlantis then i will try them and see if they are better- until then ni will do just fine......

12ml. 25w. 450F

That's a single LG HG2 (3000mAh)in a VS DNA40

Appreciate the effort to answer my question.

There was a reason to quibble about the differences between a watts or temp mod when TC cost a couple hundred dollars but now it's just a no-extra-cost feature. So the next time you buy a regulated mod just be sure it has competent TC on board give it a try and use it or don't use it. Speaking for myself, I'm hooked.

Drippers are fantastic in TC mode. Usable at last!

The KangXin Mini VF works well in Wattage Control. Of course it's the voltage it's really controlling,
the amperage results from the coil resistance and then that with voltage determines the wattage.

If you turn on TC it continues to work as before but when you hit the target temp it backs off the
voltage/wattage to maintain the temp. If I set the wattage to 50W and temp to 390F it's a pow-bang
up to temp, then it hunts. It can put out more vapor if the watts are set more like 25 watts so the
arrival at temp is smoother. It's a sophisticated feedback system so the hunting around the target
temp isn't just an on-off. Airflow plays a big role. It takes some trial and error, but it's wonderful
to have more control.

On the Mini VF anyway, the wattage doesn't default to anything in TC mode, it's one more parameter.
It's not an either-or, TC is added to WC, and as the firmware gets better, it will integrate the
different modes with auto-sensing different coil materials.

The box mods with no TC capability will be obsolete literally within a few weeks now.

The TC capable mods all seem to do buck/boost, so they can step voltage down as well as up.
You can get very low voltage/wattage when you want.
On the Mini VF down to 1 volt and 1 watt.

I'm not sure about Nickel, if it's as safe as Kanthal, and hopefully the least toxic metals will prevail.

I was thinking of buying a 60 watt SXK Vapor Flask clone. It has both Temp Control and a "Nickel Purity" adjustment.

Question: If I am using a Ni200 coil, and I am in the Temp Control mode with the temp control set to lets say 450F, does it make any difference what the watts I have previously set in the device?

I was thinking that once operating in the Temp Control mode, the voltage applied to the coil will be adjusted only by what temperature you set in the device and [not] by whether or not you have 5 watts or 50 watts set in the VW power adjustment.

Confused ...

Except, the Evic-VT for some reason feels the need to blast 30w on first use of the fire button in wattage mode. That's more than 3 times the wattage I normally use, so if i decide that TC just isn't for me, that mod is useless, and I need to sell it.

The way wattage works in temp mode is letting you decide how quick it gets to the set temp.

coilburner ... thanks for the reply

And I understand that I can't use the Temperature Control mode if I am using lets say a 1.8 ohm coil made from 28 AWG Kanthal ?

Correct...it will not fire in TC mode with a coil that high as it will assume it is kanthal. For TC to work it has to be a wire that varies resistance with temperature (Nickel, Titanium, Stainless Steel, though the new DNA200 is the only one that can run stainless natively, but many now can run nickel and titanium).

 

[Fernand]

They vary. The Evic VT as I understand defeats the user wattage setting entirely in TC
mode. The Mini VF always works in WC mode but adds the temp limit if in TC mode.

I think in time they will recognize coils they can derive a temp on,
not by base resistance but by behavior. Give it a pulse and if the resistance
varies a certain way, derive a curve and aim for the preset temp.

A good design will do it invisibly, no need to tell it what metal.

But for now they are evolving. Look for the TC design you prefer.
The "manuals" are useless. The programing will be developing very fast,
you gotta try things out, see what it does.

I built these two coils a week ago on two Tobeco Kayfun V4 Svoe Mesto clones, using Japanese unprocessed cotton, for my 95% VG 0 nic "Macaroon B" juice. The 5% is PG from flavoring, water, a few drops alcohol. B stands for Banana ;-)

The first more densely packed coil is Kanthal 28 AWG with a 1.1 Ohm resistance, operated in WC mode, wattage 8-25 watts on a Mini VF, or on a Mechanical SMPL.

The second looser coil is Tempered Nickel 200 28 AWG with a 0.1 Ohm resistance, operated in TC mode on a Mini VF with a 390-400 deg F limit setpoint; wattage varied from 8 to 25 watts. In all fairness the TC coil was used about twice as often.

There were no dry hits. The taste was great, the vapor perfecto. What's interesting is that the amount of "burning" is still significant in TC mode. The way I interpret this is that the controller can only react to the overall or average resistance of the wire. If one section of the coil is much hotter but other sections much cooler, the overall temperature appears to be cooler than that of the hot spots. The controller can't tell. I have since taken to wind Nickel coils packed together, more like the Kanthal coil here, to try to prevent big variations in the temperature.

Ideas?

 

[BlueridgeDog]

Take the cotton out and wash it...I bet there is no burning. Juice will accumulate coil junk in TC mode just like wattage mode. There are substances in the juice that do not vaporize, but instead build up on the coil.

 

[Stinkytofus]

just tried ni200 today, flavor is better, not as muted as kanthal, tank stays much cooler if my room temperature is not hot, but outside in 80-100 degrees it gets pretty hot still at 375F

i might go back to kanthal when tfv4 gets to my house though =)
