Temperatures limit of the wire

[Yarits Urfan]

I know that Kanthal SS and Nichromes can be vaped with both TC and Power Mode. With TC there shouldn't be a problem. But with Power Mode there should be a limit right? Like how much I can increase the wattage/heat below the limit before their materials vaporizes and become toxics.
How am I suppose to know that I'm still vaping below the limit? And also in theory the size should be affecting the limit right? Because the smaller the size of the wire the less heat it can hold.

metal vaporizes when it becomes a liquid... or when massive amounts of electricity pass thru it in microsecond bursts ( as in shorting out a 5000 uF cap at 10,000 V with 22 ga wire)..... most metals we use for vaping have melting points above 1100 F..

just stay below 1000 F degrees and you will be okay

Hello Yarits
In power mode the power is limited by the mod which won't exceed the amps limit on your battery. If you try to push it higher on watts the mod will cut down your voltage. Practically speaking the power is normally limited by the quality of the vape. Too high and it doesn't taste very good as you begin to scorch the cotton and get a burnt taste. I don't think anything is toxic at that stage but it sure does taste bad and would cause you to cough a lot. The smaller the diameter of the wire the higher resistance it has to the flow of electricity. The longer the wire the higher the resistance.
I'm sure someone will reply and give you some links to info you can read and better understand the process.

A mod has absolutely no way of knowing what a battery's amp limit is, that is on the user to understand and use the appropriate battery.

Nickel is used for TC not Ni-chrome.

Nickel, titanium, SS, NiFe30, NiFe48...and some more.

I thought the mod measured the voltage sag from the battery to determine if the amps were surpassing its limit thus triggering the battery warning.

Some (many?) might be doing an adequate job of using sag to trigger a "weak battery" warning, but repeated attempts may still be overstressing the cell, and the mod has no actual way to know if you popped in an aged 20A CDR, a 25 or some fresh 7A rewrap.
It's not a function I want to rely on with a mod next to my face... my pretty, pretty face.

The amp limit is a separate feature to protect the board's circuitry, generally around 25A.

Regulated mods do have maximum current draws that they won't go beyond, but if the mod has removable batteries, it's up to the user to make sure the battery(ies) they put in it will deliver that amount. In other words, you don't want to put a 10A battery into a mod that will draw up to 20A and then try to use it at its limits. The mod will still try to draw 20A at its max setting, so you need to make sure you use at least a 20A cell, if not a 25 or 30A cell.

OK got it, thanks.
