A Plasma Cutting Machine operates by using ionized gas (plasma) to cut through conductive materials. It involves a power supply, gas flow, plasma generation, a plasma torch, and the cutting process. The intense heat of the plasma melts the material, while the gas stream blows away the molten metal, creating the cut.
A CNC plasma machine uses a plasma cutter to cut thin to thick metals along a multi-axis grid. The CNC method provides an advantage over handheld plasma cutting tools due to the cut being programmed and controlled by a computer instead of human motion.
