Help! Temp control has gone crazy!

[MikeB]

I think the preference of SS is based on several features. You can use it in TC or wattage mode, making swapping mods quite easy if you have say a small mod that doesn't do TC well (or even a mech or VV setup). You can build spaced or contact coils, and even twisted, Clapton, or whatever other fancy build you might prefer. You can dry burn it.

I agree those are the reasons people are using SS, but for me personally I can reject each point (my opinion)

SS works in TC or wattage mode, but after trying TC, why go back to wattage? I tried, and vaping with flat power just doesn't compare to the smooth vape you get with TC. For me, TC is a clearly superior experience.

SS does allow fancier coil builds, but you can still do a lot with spaced coils and twisted wire is still an option. Besides, the whole point of a coil is to heat the liquid, and that can easily be accomplished with the builds allowed by Ti. A fancy coil is not a necessity.

Finally, Ti can be dry burned with a custom TCR. Oxidation is not a problem under 1000f, which is more than enough heat for dry burning.

I can see the attraction to SS, but for me and my vaping, Ti is easily the best choice. I think if I'd read up on it and started with Ti, I would have saved myself a lot of headache.

I'm glad to see things are looking up over there.

To be honest I don't really understand why SS is so popular compared to titanium. I suspect most people just don't look any further after trying it

My first TC mod didn't do SS so I had no choice but to try alternatives or I might have gone the same route, who knows. I've tried SS a few times since and it's not bad but I prefer Ti greatly.

I'm curious about that Temco wire though, someone send me a spool please

Agony, (or anyone else) have you tried any twisted Ti coils?

This 7 wrap coil is working well, but I've been running it at 520f to get the warm vape I like. Trouble is, it's disintegrating my wick.

As a spaced single wire coil, I don't think it has the mass or surface area to heat the incoming air without cranking the temp. I've tried cutting back the airflow but it's not giving me results. It produces a ton of vapor at 470f, but it's cool. My thought is a twisted 28ga coil would fix that, but it would halve my resistance. It'd be around 0.3+ ohms I think. Higher starting resistance seems to make TC work better, so would cutting it down to 0.3 ohms be bad? If so, I have some 30ga I could try twisting instead.

What do you think? Played around with any of these ideas before?

Yeah, it's pretty much all I use, twisted 28g Ti1. What are you using now?

I started out with 26g but felt it retained a bit too much heat, my juice kept boiling a little too long for my liking after I released the fire button with twisted 26.

Mine usually come in around 0,4ohm, but 0,3 shouldn't be a problem. I vape between 390 and 420 of your Fahrenheits usually, I have gone as high as 460ish but that was a little too hot for my liking. I prefer a cool to mildly warm vape as you can probably tell, so the temps you are using are out of my experience-range I'm afraid.

I've never used 30g. I have tried some 29g but it was from an unknown brand and it had a bit more metallic taste then the brand I usually use (UD, the little orange spools) so that didn't last very long. After that I just stuck to 28g since it's been working so well for me.

Excellent. I'll give it a try then.

Right now I'm just using a single strand (not twisted) 28ga Ti coil. I do 7 wraps and get about 6.0ohms.

I'd prefer to be in the 450f-470f range, and I think a twisted 28ga coil will get me there.

0.6 sounds about right, I am still using that single wire coil I mentioned a couple of days ago and mine comes in at 0,59ohm @ 7 wraps

I think you will like the twisted 28, it'll give you denser vapor and a more concentrated flavor compared to the single wire coil you are suing now. With a little luck you'll have to crank it up a little less high too to get the results you're after.

I just received another Kayfun clone by the way, I think I'm going to try a single 26 in that one, been a while since I used that.

 

[MikeB]

Temperature is a funny thing. Using TC I've learned so much about what my coil is actually DOING.

Say you like a certain "mouth feel" and temp, as we all do, for your vaping experience. There's so much more than the temp of your wire, and I don't just mean airflow. There's the temp of the ambient air, the airflow volume, how the air hits the coil and flows around/through it, the temp of your atomizer (did you just pick it up, or have you been chain vaping), as well as the mass and surface area of your coil, and finally don't forget your wick. That's a ton of variables, and consciously or not, we are manipulating all of them with how we build a coil, wick, and set the device and airflow.

The coil doesn't just produce vapor, but heats the incoming air and the atomizer. It also blocks and changes the airflow in the chamber. It finally makes sense to me how I run a small coil hot and close to the air port, and a big coil cool and farther from the air port, and get similar results. I suppose it's obvious to most of you. Maybe I'm just slow on the uptake. Lol.

I'm jealous of you and your wall of Kayfun 5s.

I'll send you a roll of this soft Ti in trade for one. Lol.

Too be honest I never gave it that much thought. I was lucky enough to stumble on a build that gave me the experience I was after pretty shortly after I started building my own coils, so for me it was a very simple path with only a little fine-tunning along the way.

Making a juice from ingredients I didn't have a sensitive reaction to was the challenging part for me personally, haha.

But, I'm only up to four now..

But that's a deal, lol

I have a stainless SXK mini (still holds a little over 4ml) I can part with. I think you'd like it, it gives a much hotter vape then my full size versions at the same settings.

I use 24 awg Ti on my KF5. No problems with temperature control and titanium running a 0.200Ω. I actually run lower than that(0.140Ω) with one of my dual coil tanks, with no problems.

One thing about twisted wire is, less contact surface under those small screws.

Haha. That's very generous, but it's not a fair trade. You can trade about 5 bucks to Temco and they'll send you a roll.

I use 24 awg Ti on my KF5. No problems with temperature control and titanium running a 0.020Ω. I actually run lower than that with one of my dual coil tanks, with no problems.

Is that decimal in the wrong place? 0.02 ohms? Must be 0.2 ohms. Still, that is impressive that it doesn't make the TC sloppy. I'll have to try it.

Yea, good point about the screws and twisted wire. I noticed on my twisted SS coils I have to really be sure the wire is fully trapped under the screws and the screws are tight.

 

[OhTheAgony]

I think Temco wants a lot more money to ship it to me but I haven't checked myself to be honest. Ordering from the US usually gets expensive over here once our customs starts to stick it's nose in so I only do it if there are no other options to get what I want.

But yeah, even without customs shipping would probably take the fun out of a trade.

I still think you'd enjoy that SXK though, they sell 'm at Fasttech as well as at 3fvape

Ah. Yea, temco gives free shipping to us here in the US. I didn't realize where you were located. Lol. I still think it'd be worth making an order. Just get like 250 feet so you won't have to order again. It's supper easy to work with.

And I'll check out the SXK. I'm loving my K5, but it couldn't hurt to try another.

 

[Eskie]

I've got to say I love Temco. But that's in the US. No idea of shipping costs from them to overseas, but it's hard for me to imagine there is not a similar company in the EU with shipping that has to be cheaper than from the US. These types of wires are pretty common for industry to use.

Isn't Temco sold under the name VapoWire from some vendors??

@MikeB I think I know what you meant in your first post about that scorched hit! A while back I was using some sub-ohm tank and it was vaping fine then one hit felt like Scorched Fire. Swapped coils, didn't think to empty out the e-liquid for new, and the e-liquid tasted scorched. So after cleaning the tank out, and a another new coil it was fine. I think it was one of Joyetech's tanks lol

Looks like you have gotten some great advice here!!

Yes I have gotten some great advice here! Just went back and read my first post, and wow -- I had no idea what I was doing, Lol. I feel like I've really come a long way in my understanding of how all this works and like I can trouble shoot problems on my own now. It's all thanks to this wonderful community (and the stubbornness not to give up. Haha.)

Edit:
Oh yea, and I hate that scorched taste. If you catch it fast sometimes your wick/coil can recover from it. Most of the time I'll just change them both out though.
