Plasma Cutter
A plasma cutter is a tool that cuts through electrically conductive materials using a jet of superheated plasma. It provides fast, accurate cutting on metals such as steel, stainless steel, and aluminium, making it a highly efficient alternative to traditional mechanical methods.
Technically, a plasma cutter works by creating an electrical arc between an electrode inside the torch and the workpiece. Compressed gas, such as air or nitrogen, is forced through a nozzle where it becomes ionised, forming plasma. The plasma reaches extremely high temperatures, sufficient to melt the metal, while the high velocity of the gas stream blows away the molten material to form a clean cut.
Plasma cutters are available in portable handheld formats as well as larger, CNC-controlled systems designed for industrial production. Advances in plasma technology, including high-definition plasma, enable narrower kerfs, improved edge quality, reduced dross, and greater energy efficiency. These tools are valued for their ability to cut both thin and thick materials quickly and precisely, with applications ranging from light fabrication to heavy manufacturing.
