Therion BF DNA75C and Ni200

[William Hawkins]

I'm using a Therion BF DNA75C mod in TC mode (DJLsb's Ni200 profile) with Ni200 nickel wire in a Vandy Vape Pulse 22 single coil RDA.  I've tried two different gauges of wire - 26ga and 28ga.  I'm making my own coils - spaced.  The mod works great with this wire when it's in TC mode - provided the coil build stays below 0.100 ohms.  If I make a coil that reads 0.100 ohms or higher the coil will 'fire' - heat up and glow - on both my tab and mod.  It is my understanding that this is not good, and that the mod will not be operating in true Ni200 TC mode with a coil that can 'fire' like this.  As long as my coil build stays at 0.090 ohms and lower the coil won't fire/heat up and glow unless there's a wet wick in it.

 

Is this normal for Nickel wire?  With such a low resistance value I have to have the power set to at least 60w and the temp to at least 525*F to get a decent lukewarm vape.

Tab - meaning external ohm reader, build deck? If yes, it has no clue what material (wire) you're using, and just firing at its setting. Same thing for your mod if it doesn't know it's nickel.

I've built up to .3Ω Nickel with no issues at my regular 390-420°F. (no longer my regular wire, but not due to it being Nickel. I mainly now use it for Cotton burn tests)

I'd check for a solid connection and build using Atomizer Analyzer, BF's are not a friendly environment.

And welcome

Hi Wayneo.  Thanks for the response and info.  I'm new to vaping, if you couldn't tell.  But I have been doing a lot of self-help thru reading and Youtube watching.  From what I've managed to learn about Ni200 wire, it should never 'fire' unless it senses a wet wick in it.  When I use it on my Therion BF mod, and set it to the Nickel profile, it works as it should, but only if the coil's resistance reading is less than 0.100 ohms.  If I make a coil that reads at 0.100 ohms or higher, and put it on my mod, with a dry wick, it will fire and burn the wick.  Believe it or not, the same thing happens when I put the RDA on my CoilMaster 521 'tab' ohm reader/build deck.  I've tried this on multiple RDAs and multiple mods.  Same results.  I used Atomizer Analyzer to check it.  It looked fine - steady ohm reading.

 

I'm just trying to figure out if I'm doing something wrong.  With coil builds at resistance levels this low I have to crank-up the power and temp settings to near max.  If I manually adjust the resistance setting for the coil to something higher I can reduce the power and temp settings, but I will occasionally get a 'Temp Protect' warning from the mod.  And I'm not sure if it's safe for the mod, coil, and batteries to do this.  Like I said, I'm a noob.

 

Everything is working as is.  I'm just curious as to why I can't properly use a Ni200 coil that reads 0.100 ohms or higher properly.

OK,

Have you upgraded your firmware to the latest version? 2.0 SP8 or 9 I believe?

Daniel's a great reviewer, and some of his comments are time and firmware specific. Any reason why you're using his Ni200 profile?

Any coil, with dry wicks in TC (like your 525F) can burn, because it's past the burn point of cotton.

It's Nickel ........ ohms out low ......... doesn't require much power to reach and maintain temp.

I have the same curiosity as you.

Can you do a printscreen of device monitor with the following ticked. Power set, power, temp set, temp, cold ohm, live ohms.
