Being kicked from TC to Wattage mode

[GeorgeS]

The two popular things that many mods will "kick you out of TC mode" are:

• to high of a cold or hot resistance
• wire resistance does not change according to known curve

Up until sometime last year many/most mods would switch to power mode automatically if the coil resistance was higher than 1.0 ohms. Joytech (and their partners) changed this to 1.5 ohms. Personally I've not gotten 'kicked out of' TC mode on Joytech mods with cold coil resistance of 1-1.5 ohms. (YMMV) My DNA75's will 'kick me out of' TC mode if the hot resistance is higher than 1.4 ohms.

"The curve" is what provides YiHi chips the 'dry coil protection' on the one end and what 'kicks you out of TC mode' on the other end. (YiHi chips won't do this)

If the coil heats up to quickly IE acts like there is no juice+wick acting like a heat sink the high end YiHi chips will cut power and give a 'dry coil' error message.

Similar but on the other end of the spectrum, if power is applied to the coil and the resistance is not changing or changing as much as the mod "thinks" (built in curve or logic of some sort) then the mod might assume that non-TC wire is in use and switch automatically to Wattage mode. One of the primary reasons for this is poor connections causing the mod to read the cold resistance of the coil higher than what it really is.

IMHO: building very low resistance coils with very low TCR wire compounds the possible effects of errors in resistance.

Personally, I vape on the other end of the spectrum with higher than TCR=300 wire and resistances greater than 0.3 ohms. YMMV.

Yeah I have had the RX300 for a couple weeks now and I was using my goon on it and I wanted a bigger RDA so I ended up getting on here asking people their opinions of larger RDA's and someone mentioned the 27mm Mason. I looked it up and ended up pulling the trigger on it and glad I did. I love this thing. Big enough to build large aliens and massive airflow so you can crank up the watts. I have a dual 7 wrap SS aliens over 4mm and have a bit of room still. This thing can chuck the clouds. Also able to lower the airflow for flavor. I would like to use it in TC so I'm gonna play around with this and the coils I build and see if I can get it to work and stay in TC.

How's the overhang?

@Yaroon, I'll try that today. After I get home from work tonight I plan on building a coil under .10 and see what happens.

Building that low will most likely exaggerate the problem rather than stabilise the mod. Lower resistance means less increase in resistance with temperature increase, making it harder for the mod to regulate correctly. If you've only tried complex coils I suggest trying coils of regular single wire.

Good idea. I'll try that first.

Nice. Wasn't sure with the 510 placement how something over 25 mm would look. I still think it could have been back a bit more for the 30 mm tanks out there.

Just built a dual fused Clapton on the limitless classic... 6 wraps on a 3.5mm ID at 0.14ohm... Once again it kicked me back to VW.
So it ain't the Aromamizer plus, It has to be the wire
Perhaps I should buy a different gauge

Or, I guess SS is just not for me and should stick with kanthal

This is the only thing I'll try now. I love exotic coils such as fused claptons, alien, juggernaut, fused staple staggered etc etc. it surely gives this extra little boost with regards to flavor and clouds on kanthal, so I was hoping it would do the same on SS

I have some SS 316L 26g wire.. Just a simple single wire.. I'm guessing this would lack the flavor and clouds like the fused Clapton SS can give,..

Are these premade prewrapped Claptons? Rather than shooting for such a low resistance, how about a dual 7 wrap 3 mm ID and get the resistance above 0.25 ohm? There is no advantage to lower ohm builds in TC. In fact it can essentially be ignored so long as you fall into the operating range of the board/mod. It's not like a mech. The TCR is pretty low with 316L and you're only making it "harder" for the mod to perform properly in TC mode. You might not be getting kicked out to power mode if you're around 0.3-0.5 ohm, and the vape will be the same.

As you see in the pics it does overhang just the slightest little bit. I have a silicone case in it right now till I get my wood skin from Wüd and you can't even tell with the case on it. I wanted a 30mm until someone showed me the overhang of a 30mm and this person had a 27mm Mason and I asked about overhand and he sent pics to me similar to what I sent you. I knew at that point I didn't want to go over 27mm. I would have thought with all the real estate on top of this 300 that Jaybo and Wismec would have thought about customers that had or use 30mm or bigger RDA's and RTA's and they would have backed the 510 closer to the center. I mean if they would have moved it back 1/8" to 1/4" you would have been able to put the larger RDA's on top with no overhang. Not sure why they didn't do it that way.

Making the coils myself, never used premade ones

3mm @ 7 wraps... Will try that tomorrow

My 30mm Aromamizer plus has little overhang,... But it isn't annoying at all. When my fist is around the rx300 and the finger on the fire button it cannot even be seen. It would have been nice if the 510 connection would have been moved just a few mm towards the middle, but it isn't that much of an issue at all for me

When using a 40mm atty I'm sure it would start being awkward though

So I was playing around tonight and look into my wire box and found some 26 gauge Ni200 and figured I'd see what happens. I build dual micro coils 8 wraps on a 4mm. Ohms out at .14. Put it in Ni mode and she seems to be staying in TC. Next I'll put some 24 gauge SS316L and wrap a dual micro to see if she stays in TC mode. Figured I'd give y'all an update on my end.

FYI that was on my 24mm Buddha

Well I lied. I only have Ni80 in 24 gauge. I'll have to put an order in for some SS wire. I thought I even had 22 gauge SS but I was wrong about that one too. Only Ni80 ‍‍

Just did 7 wrap 3mm with the SS wire, 0.12ohm
Lower in ohms than expected

This also kicks me back to VW

If the wire is indeed ss and not something else you have a connection issue somewhere or your build is unstable.

I wonder why my build I didn't last night on the 200s works but yours doesn't. Something isn't kosher with your builds. I'm not thinking it's the mod. My build worked on both the 200s and the 300. Throw more wraps on a coil and try to get it up around .2 or so and see if that works.

Weird that the Mason overhangs on your RX300, but when I sent you pics of it on my RX300, there was no overhang at all.

Remember?

It didn't hang over at all? I remember you sending me the pics but I don't remember exactly if it hung over at all? I know it doesn't look like it hangs over until you look at it at a certain angle like the pic I put on here. At that angle it looks like it hangs over a bit but not bad at all
