A plasma cutter is a type of thermal metal cutting tool that uses working gas and plasma arc with high-speed & high-temperature as the heat source to melt the metal locally, and blow away the molten metal with high-speed airflow at the same time to form a narrow plasma cut seams. It is used to cut various metals, like carbon steel, stainless steel, copper, aluminum, cast iron, and more. It makes it possible to cut through electrically conductive metals with precision. It features with high cutting speed, thin cut seams, low deformation, small heat-affected zone, easy-to-use, and energy saving. With the pilot arc, it will generate a low power plasma arc in the air, which make the cut with lower cost. It is used for sheet metal fabrication, metal structure making, machinery building, repair shop, drilling, digging, beveling, patching and more metal cut projects & plans.
