The plasma cutting process as used in the cutting of electrically conductive metals utilizes electrically conductive gas to transfer energy from an electrical power source through a plasma cutting torch to the material being cut. The basic plasma arc cutting system consists of a power supply, an arc starting circuit, and a torch. These system components provide the electrical energy, ionization capability, and process control that is necessary to produce productive cuts on a variety of different materials. We offer MIG, TIG, and arc welding services.
