What are the different types of plasma cutting systems?
Plasma is a condition of matter and is similar to gas because it has no specific shape or volume. It can be created when the electric current is sent through an inert gas and compressed a narrow plasma burner that creates and performs a highly charged electrical arch. This charged compression results in a very high temperature, giving the plasma the ability to cut a range of thickness and types of metal materials if this material can lead electricity. There are three main types of plasma cutting systems: Pilot ARC process, high frequency contact process (HF) and computer numerical control process (CNC).
systems that use the pilot arch process use a highly efficient electrical circuit that creates a very small spark with a high intensity inside the plasma burner body, leading to a small amount of plasma gas before the nozzle even touches the metal. When the arch comes into contact with the cutting surface, this electrical conductivity is then transmitted to the cut of the metal and creates an electric OBWater that ignites at temperatures of up to 45,000 degrees Fahrenheit (almost 25,000 degrees Celsius). This method is used in CNC machining to reduce problems that can be caused by high -frequency electricity reaction with a computer machine and generally creates a much cleaner metal cut and blows any residues.
plasma cutting of systems using HF contact process use a high -frequency circuit generated by an internal, negatively charged electrode that ionizes gas, creates spark and ignition, similar to the spark plug, instead of using a pilot arch with lower voltage to start plasma formation. With this method there are more residues and cleaning, but the nozzle creates a very concentrated, stable plasma arch at the tip of the plasma cutter. Cutting begins when the Arc plasma connects to the metal, not before it connects.
systems that use the CNC plasma cutting process use SVA cuts to determine SVA cutsSqueelling computer -generated design. These CNC units are larger, solid machines that should use pilot arches to alleviate reactions caused by high -frequency electric interference. CNC plasma cutting systems are able to create clean, sharp, fast and complicated automated cuts using computer programming.
plasma cutting systems have become advanced, flexible and more affordable and can be used in various applications. The selection of plasma cutting systems will vary depending on factors such as purpose, volume, speed, accuracy and type of material and thickness. Other factors that could affect the selection include the required accuracy of reduction, portability, availability of voltage, user level, safety requirements and costs.
