Frequently asked questions about oxyfuel cutting

Pure oxygen, introduced in a fine, high-pressure stream, is then directed toward that heated section of steel. As the steel is oxidized and the oxygen stream helps to blow away the resulting slag, the "cut" occurs. In mechanized systems, the preheat and oxygen stream is then moved at a constant speed to finish the cutting process.
