Plasma Cutting Machines

Both hand held and robotic torches used in CNC plasma machines work by creating an electrical arc between an electrode to the metal surface being cut through an inert gas that is blown at high speed through a narrow nozzle.

The heated gas is so hot that it melts the metal surface, and moves so fast that it blows molten metal away from the cut, resulting in a relatively small heat affected zone.

Although the science behind this equipment is impressive, relatively minimal training is required to learn how to use plasma cutting machines(depending on your application).
