This term is normally used in short circuit conditions and the values are used to perform co-ordination studies in electrical networks. I 2 t parameters are provided by charts in manufacturer data sheets for each fuse family. For coordination of fuse operation with upstream or downstream devices, both melting I 2 t and clearing I 2 t are specified.

To properly explain how a plasma cutter works, we must begin by answering the basic question “What is plasma? In its simplest terms, plasma is the fourth state of matter. We commonly think of matter having three states: a solid, a liquid, and a gas. Matter changes from one state to the other through the introduction of energy, such as heat.
