A cutting torch is a handheld gas-powered tool used for cutting and shaping metal materials, especially steel. It is commonly used in welding, fabrication, construction, and metal repair works. The torch consists of a handle, control valves, mixing chamber, and a nozzle that directs a flame produced by fuel gas and oxygen. It is designed to generate high heat capable of melting and cutting thick metal surfaces efficiently.
Operation:
The cutting torch operates by mixing fuel gas (such as acetylene or LPG) with oxygen to produce a high-temperature flame. First, the metal surface is preheated until it becomes red hot. A stream of pure oxygen is then released through the torch nozzle onto the heated area, causing rapid oxidation and cutting through the metal. The operator controls the flame intensity and oxygen flow using the torch valves to achieve clean and accurate cuts.
