A cutting torch is a tool used to cut through metal by using a flame produced from a mixture of fuel gas and oxygen. The most common fuel gases are acetylene and propane. The torch has a nozzle where the gases mix and ignite, creating a high-temperature flame that can easily melt metal. Cutting torches are widely used in industries such as construction, manufacturing, and automotive repair. They are essential for tasks like welding, metal fabrication, and demolition. Safety precautions, including protective gear and proper ventilation, are crucial when using a cutting torch to prevent accidents and injuries.
