I've been vaping and doing rebuildable a for a while now and on a few occasions I have had a problem with my coil that I'm not sure what is or why it happens. All I know is that I have figured out how to prevent it but I am much more interested in the why.
So occasionally when I build a coil, (and this has happened all the same at different ohms and resistance wires) after I'm done reading the ohms and making sure it is safe I put the atomiser on my mod and hit the button to run current through it for the first time so I can begin to put last minute touches on the coil and make sure it heats evenly. Well when I hit the button it glows very hot and the coil will basically curl up and disfigure from the heat. The way I have solved this is to hit the button a few times and let it slowly heat up until the wire hardens a bit and stiffens an then is good to go.
So my question. Is this "coil sag" as I have heard, why does this happen? And what exactly is happening.
I'm by no means new to vaping or electronics but I'm eager to learn more everyday
