In order to understand what this instrument does, first it’s important to know what plasma is. Matter has three forms: liquid, gas and solid.
How, exactly, does a plasma cutter work? Well, this tool sends an electric arc through a gas that is passing through a constricted opening. With this extreme heat, plasma cutters elevate the temperature of the gas and convert it to the fourth state of matter, called plasma.
As a result, this instrument can pass through metals like steel, aluminum, brass and copper with little or no resistance. This sharp welding process allows for cleaner, sliced lines and sturdier constructions.
