Question

Quizplus · Accepted Answer

Oxygen is the gas that produces the fastest and cleanest cuts on mild steels. When combined with a fuel gas (such as acetylene), it creates a flame that can reach temperatures exceeding 6,000 degrees Fahrenheit, which allows for quick and efficient cutting of the metal. Oxygen also reacts with the steel to form iron oxide, which is easily blown away by the cutting stream, leaving a clean, smooth edge.
