A used plasma cutter or used plasma cutting machine consist out of a plasma source and plasma cutting torch which uses a copper nozzle to constrict the gas passing through it while applying an electric arc. The arc jumps from the electrode to the material and the temperature of the gas is elevated to a point where it cuts through the material.

A used CNC Plasma Machine is a system that moves a plasma torch in a specific path by using a Computer Numerically Controlled system. A used CNC Plasma machine typically consist out of a water bed or dry bed system with cantilever or gantry structure for the X and Y-axis travel of plasma torch.
