Explain How A Plasma Cutting Machine Working Principle

To properly explain how a Plasma Cutting Machine Working Principle, 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.  For example, water will change from a solid (ice) to its liquid state when a certain amount of heat is applied. If the heat levels are increased, it will change again from a liquid to a gas (steam).  Now, if the heat levels increase again, the gases that make up the steam will become ionized and electrically conductive, becoming plasma. A plasma cutter will use this electrically conductive gas to transfer energy from a power supply to any conductive material, resulting in a cleaner, faster cutting process than with oxyfuel. 

Plasma Cutting Torch – The function of the plasma torch is to provide proper alignment and cooling of the consumables.  The main consumable parts required for plasma arc generation are the electrode, swirl ring, and nozzle.  An additional shielding cap may be used to further improve cut quality, and all the parts are held together by inner and outer retaining caps.
