The three states of matter, are solid, liquid, and gas, right?

Wrong!

Your sixth-grade science teacher didn’t tell you the whole truth. Consider the fourth state of matter:

Plasma.

Plasma welding is a superheating of gas that becomes highly conductive and, in welding, allows for the transfer of an electric arc.  When you pass a gas through this electric arc, it breaks the gas down and forms what is called a plasma stream.

Dr. R. M. Gage is credited with the introduction of plasma into the welding industry in 1955, and in the 1960s it was integrated into microplasma and high-current applications.
