Does SS increase in resistance while firing?

[Frogzx]

Just noticed that my quad core SS fused claptons jump in resistance as I am firing, usually by .3 to .4 max. A little freaked out as I never paid attention to it before..

Could there be something wrong with my coil or is this normal?

 

[Myk]

Yes. That's how it works in TC.

 

[Frogzx]

Yes. That's how it works in TC.

I'm in VW right now though, still normal for that?

 

[flavourchaser]

can you lock the resistance with your mod? That's what I do. Also make sure the legs of the coil is secured tightly

Yes. It doesn't care what you're in, it gets hot the ohms go up predictably.
Some mods may not show it.

If you can lock in the cold (room temperature) ohms you should. *And even when locked in some mods show the change.*

I'm on the Pulse 80w, I don't believe you can lock the ohms? Or if you can I don't know how to. If it's normal though I just wont worry about it!

Yup, the resistance always increases as SS wire gets warmer. That change is what TC circuitry uses to gauge wire temperature. It's perfectly normal

I vape SS in VW mode with various mods all the time and it works very well. Don't worry about the resistance change. It doesn't matter as the VW circuitry will still keep the watts you set.

I don't lock the resistance if I'm vaping VW. I am not even sure if it would make any difference in VW mode, it really is a TC 'thing'.

It's normal.
The bad thing is some mods read the resistance when you press the button (why locking the resistance is good) (and some mods lock the resistance in the background). So if you press the button twice to take multiple puffs in a row each one is seen as a higher resistance.
The worse thing is some mods poll constantly so it will change during the puff. (I've only had that long ago.)

I don't lock the resistance if I'm vaping VW. I am not even sure if it would make any difference in VW mode, it really is a TC 'thing'.

It may. It depends on how the mod works.
At least with SS it's not completely bad if you know what's going on and how to manipulate it. It can work like hotboxing a cigarette.

0.3 to 0.4 Ohm jumps seem a bit high for SS. Idk, maybe check the post screws?

That's a good point Zakillah. I originally read the OP to mean the resistance changed from 0.3 to 0.4 ohms. The coils used are going to be quite low resistance to start with, so if they go up by that amount there is something else going on.

@Frogzx, a bit more info might help here. What is the cold resistance of the build? What atty are you using? Is the resistance going up by 0.3-0.4 ohms? Have you checked the build connections in the atty? Have you have used another atty on that mod and is the resistance more stable with it?

Post screws are secure. I even put another coil in with the same results. I also think I misspoke, its .03-.04. So for instance this one is jumping from .37 to .40-41

That clears that up. It's normal for SS

Ain't nothin'

Yes.. resistance changes for All metal when heated or cooled.... this variation is what allows for Temperature based regulation.

NOTE all regulated mods are Variable Voltage..
VW and TC are user input schemes to determine the algorithm to be used for calculating the voltage to be output to the coil.

That's only a .03 to .04ohm increase. Not .3 but .03. From .37 to .40 is a .03 increase. I doubt that while vaping you could even tell the difference

Does SS increase in resistance while firing?

Actually, ALL Coil Wires Resistance Increases when they are Heated.

It just that Some Alloys Resistance Increases more than others. And that is what makes TC Possible.

No, that's totally normal. Mods these days are intelligent enough to deal with that in watt mode. I use SS because I exclusively use temperature control mode. The mod senses the resistance change and calculates the temperature of the coil from it. Now nickle or titanium changes much more drastically. I was using nickle for awhile a couple years back. If all you do is watt mode then you can use Kanthal. As it is you could switch to temperature control mode if your mod has it and set it to SS and use it that way.
