Good Titanium Wire Sources

[Croak]

Finally, any time you are working with temp control, you need to be working in low resistance ranges. There have been some mentions here of coils in the 0.3 to 0.5 range, which is way too high for temp control. As the wire heats, the resistance increases and there is no headroom. Personally, I wouldn't go above 0.15. I speak from personal experience. My first build came out way to high (0.23) and there were dry hits and erratic heating/cooling. Stay low and you are good. If you are having to run in Ni200 mode to compensate, your Ti build is too high.

I disagree. Lower ohm builds have no margin for error. Being a bit off on the resistance reading is much more of a problem on a 0.1 ohm (or lower) build than it is on say a 0.3 ohm build. Plus, battery life is better on the higher ohm builds, often substantially so.

As for headroom, many mods on the market today support as high as 1.0 ohm in TC mode. Even on the ipv D2 and its published 0.3 ohm limit, it's a non-issue.

My titanium wire of choice is 26ga, and with the dual coil builds I prefer, they come out to 0.23 or higher, and it works just dandy on my ipv D2 in Ti01 mode.

Most likely, any issues you had were directly related to that particular build, but NOT the resistance per se. Too much coil mass can be a major source of issues, which is why I dislike low gauge titanium. You're probably just having an easier time getting solid builds with smaller coils/fewer wraps with that thicker wire you have.

I dont want to question your personal experience, but for most others this is just not true for all the reasons @Croak states.

I had bought some pre-wound coils which had 0.15 and 0.2 on the side and once figured if it was good enough for the factory built stuff, it was good enough for me.

Yeah, I read that 0.3max thing to. However I'm currently sporting 0.34, 0.36 and 0.98ohm builds.

I seem to recall something like the higher the initial resistance, the larger the resistance range and more granularity of resistance and thus temperature measurement.

What do you mean there is no "headroom." I am using a ~.3Ω coil and it is vaping right along just fine on my IPV D2.

And I am vaping, at this moment, on an rda (Tugboate v2 clone) build which is 28 guage Ti, 1.0 ohm starting resistance, spaced, in temp mode. It is working just as I would like (Kangxin mini). I've mentioned before, the reason for the higher ohm build is for battery life. It seems the same as my 1.5 ohm kanthal builds. The only point I can see for going to lower ohms is to enrich battery companies.

Lower ohms don't affect battery life. Wattage does. If you want longer battery life, turn the power down.

When I was vaping .15 ohm nickel coils I needed 40 watts max to get the results I wanted. With a 1 ohm nickel coil 20 watts max gets the same result. Lower ohm coils drain the battery faster for the amount of heat produced.

What gauge wire were you using for the .15Ω coil? And what gauge wire for the 1Ω coil?

Building a 1Ω coil with nickel must be a PITA. Even with 32 gauge wire, you need over 30 wraps around a 3mm bit.

I use 28 guage in all cases. nickel has lower resistance than titanium. 1 ohm coil is not practical with nickel. 1 ohm Ti = 28 guage, 3 mm, about 13 wraps I believe. When that 1 ohm Ti coil heats to 480 degrees the ohms rises to 1.8-2 so it's working very efficiently.
