Confused about using Stainless Steel wire in my Sapor

[Disturbance]

Hi, Ive been vaping for a year now and have been through various mods and tanks.
Right now I have an X Cube 2 with Sapor RDA
I was using Kanthal at first but now have some SS 316L wire so that I can use the temp control.
However I am confused in regards to weather or not its ok to heat up those wire when building the coil.
I have seen some posts exclaiming that under no circumstances must you allow the SS wire to glow red, however there are plenty of YouTube videos showing plenty of people heating up that wire till it glows... so yeah, I'm confused.

Any advice please

Nat.

It's just kind of a general rule of thumb to never glow TC wire, so SS often gets looped into it. Ni/Ti will produce dioxides if heated to much, and will melt if glowed constantly. With Kanthal, you can just keep applying power, but SS you have to Pulse. Kanthal can glow and cool constantly without becoming overly brittle, but SS is the opposite, the more it's glowed and cooled, the more brittle it'll become (same principle as case-hardened steel). So yes you can "glow" SS, but not under constant power, but by pulsing (and shouldn't be done often, just build, pulse, adjust, and be done with it, don't keep playing and pulsing it)

Thanks
Im more worried about poisoning myself than making the wire brittle.

Because of the inherent nature of SS (Various alloys used to create it) it has the potential to release toxic fumes. Different SS mixtures will contain different amounts of certain alloys. Some mixtures may contain Nickel, while some don't. This is why it's better to be safe than sorry with SS. Unless you now for absolute certain that your particular type of SS wire has no potentially toxic alloys in it, then it's just better to not glow them if you don't have to.

Hmm ok, so, and please forgive my ignorance... how do you build a coil without glowing it then? If you dont glow it then you have no way of knowing if its heating up evenly no?

Spaced Coils, as long as there's no wraps touching each other, there's nothing to short on / no hot spots, so no need to check them, it's the same thing for Ni/Ti coils as well. Same amount of wraps, same wire gauge, same ID, just make sure it ohms out high enough for your mod to fire it and you should be good to go. Here's dual slanted 7 wrap, 24ga A1 in my Avocado RDTA, you can see none of the wraps touch. TC is a little harder though due to the fact of it's super low resistance, meaning you need more wraps around a smaller ID in single coil to achieve higher resistances (dual coils will half the resistance, usually causing it to ohm out too low)

Great, thankyou
