What is a gas cutter? A gas cutter is a tool that slices through metal using a flame produced by burning a gas mixture. It primarily utilizes a combination of oxygen and acetylene for its cutting process.
Gas cutters serve as essential tools in industries requiring precision metal cutting and shaping. They harness the chemical reaction between oxygen and a fuel gas—typically acetylene—to generate a high-temperature flame. This flame reaches temperatures hot enough to melt metal, allowing for clean, controlled cuts.
By adjusting the ratios of oxygen to acetylene, operators can tailor the flame’s intensity for different materials and thicknesses, ensuring versatility across a range of applications. Safety and skill are paramount in handling gas cutters, as the combustible gases and intense heat present significant hazards. Proper use includes adhering to safety protocols and wearing protective gear. Gas cutters are indispensable in sectors such as construction, fabrication, and salvage operations.
