The oxygen-acetylene torch has two main functions: 1. Cutting: When pure oxygen is directed at a heated piece of metal, it causes rapid oxidation (burning). The torch is used to preheat the metal to its ignition temperature, and then a high-pressure stream of oxygen is released to cut through the metal by burning it away. 2. Welding/Brazing: The torch produces a very hot flame (around 3,500°C or 6,330°F) by mixing oxygen and acetylene. This intense heat can be used to melt metals together (welding) or to melt a filler metal to join two pieces of base metal without melting them (brazing). What's next?
