Flame cutters are tools used to cut through metal using a high-temperature flame. They work by mixing oxygen with a fuel gas, such as acetylene, to create a flame that can reach temperatures over 3,000 degrees Celsius. This intense heat melts the metal, allowing it to be easily cut or shaped. These tools are commonly used in industries like construction and manufacturing, where precise cuts are needed for metal components. Flame cutting is often preferred for its speed and efficiency, making it a popular choice for tasks involving thick metals, such as steel and iron, in various applications, including welding and fabrication.
