Oxy-fuel cutting is a process used to cut through metals by combining oxygen and a fuel gas, typically acetylene. The equipment consists of a cutting torch, which mixes the gases and produces a flame that can reach high temperatures, allowing the metal to melt and be removed. During the cutting process, the operator directs the flame onto the metal surface, heating it until it reaches its ignition point. Once the metal is hot enough, a stream of pure oxygen is introduced, causing the metal to oxidize and burn away, creating a clean cut. This method is widely used in industries such as construction and manufacturing.
