Plasma Cutting
Plasma cutting is a process that uses a high-velocity jet of ionised gas, called plasma, to cut through electrically conductive materials with speed and precision. It is widely used to cut metals such as steel, stainless steel, and aluminium in applications ranging from fabrication to repair work.
At a technical level, plasma cutting operates by creating an electrical channel of superheated, electrically ionised gas between the cutting torch and the workpiece. A power supply generates the arc, while compressed gas (such as air, nitrogen, or oxygen) is forced through a nozzle, becoming plasma. This plasma reaches temperatures high enough to melt metal, while the momentum of the gas blows away molten material, leaving a clean and precise cut.
Modern plasma systems can operate with advanced controls, including CNC integration, high-definition plasma technology, and automated gas consoles. These enhancements provide fine kerf widths, higher cutting speeds, reduced dross, and improved edge quality. Plasma cutting is especially effective for medium to thick materials, and its efficiency and versatility make it a cornerstone of industrial metalworking.
