Using titanium wire with any TC Mod: Ni-Ti conversion chart
Titanium TC? Yes you can! - even if your TC mod only supports nickel. Use the charts below to find the equivalent temperature setting for Ti when running in Ni-TC mode.

------------------------------------------------
Edit: There is a better online calculator for this now from Dirk Oberhaus (aka Obi, German youtube reviewer). Also note that the temperature coefficient of Ni200 in the vaping range is more like 0.0053 than 0.0062 (most often quoted value), or 0.0064 (the value used in charts below).

To use Obi's TC conversion calculator, enter the temp coefficient of the wire your mod is calibrated for in the "Koeffizient 1" box, the temp coeff of the type of wire you want to use in the "Koeffizient 2", and the desired temperature as "Soll-Temp". Hit enter and the recommended mod setting will be displayed next to "Einstell Temperatur".
------------------------------------------------



Temp coefficient data sources:

Edit: Detailed data sheet for Ni200 suggests less discrepancy between Ni200 and Ti than the above tables indicate by about ~40F/20C near vaping temperatures.

Now we just need Ni200 mods allowing to set the temp that low ;-)

Most if not all of them do go down to 200F/100°C.

Oops. Swapped some numbers/columns while reading on my mobile. Nevermind

I'll try that. Maybe it will make Titanium not suck so badly in my K4. I was about to rebuild it with Ni200 because it's too hot.
KF4 Leaking? For a more secure seal, replace the o-ring #16 with one that is 1.5mm cross section. SKU 1536606 or SKU 1536607

Maybe. A typical KF4 will run hotter for a given temp setting than a dripper because it's got significant internal resistance. With a higher resistance titanium coil the internal resistance should not affect the temperature measurement as much.

But you'll still have to make some allowance because Ti also responds less strongly to temperature change than Ni, which negates the advantage of the higher resistivity of Ti to some extent. A Ti coil at twice the resistance of a Ni coil will have about the same error in temp reading as the Ni coil due to atty/510 internal resistance.

Cotton dry burn test is probably the best way to find the correct setting - as long as the mod has resistance lock instead of a resistance randomiser like mine.

Naw...I tuned my 316L K4 up before giving it over to TC. It's very stable. I've never bought into the hater bullshit. The K4 has a tiny chamber so it has different requirements from a typical dripper.

This definitely works just fine, so simple to just reduce the numbers (once you know what they should be)

Awesome. Good to know but I'll let my chip do the figuring out for me.
Guess atm, Ti is the way to go.

BTW, is tht chart good for all mod?
Sure is so far off between temp set vs temp target.
