Welcome to

CNC Plasma Cutting Sheet Metal Prototypes



IMAGE PlasmaCam DHC2 and Hypertherm Powermax 380 power source.

The DHC2 uses a non-contact cutting process eliminating the need for costly tooling.
Advanced Z axis control maintains torch height distance for uniform precision cutting.

Basic explanation - plasma arc cutting:

 Plasma arc cutting is a process where pressurized air is forced through small holes to form a rotating vortex inside a plasma cutting torch. This vortex is then electrified to ionize the air and superheat it to 15,000 + degrees Fahrenheit. This heating causes the ionized air, now called plasma, to rapidly exit the vortex chamber through a very small hole in the plasma torch cutting tip. This escaping plasma forms a tiny hot tornado, which when positioned properly above the surface of light gauge sheet metal, removes a narrow pathway of metal in any direction the torch moves.

 Plasma arc cutting is a non-contact process, meaning, the only thing touching the sheet metal during the cutting process is the tiny hot plasma tornado. The width of the plasma cut pathway is around .030 of an inch when cutting sheet metal.
