  • Cutting Process Overview | Hypertherm

    A thermal process uses heat to cut or melt through the material being cut. Examples include oxyfuel, plasma, and laser cutting. Here’s how each works: Oxyfuel creates a chemical reaction between the oxygen and steel that is so hot (about 1,800°F) the metal softens, and then melts. Plasma uses a high temperature ionized gas to produce a very ...
