The oxyfuel gas cutting process results in considerable sparking and flying molten metal.

• A. True
• B. False
• C. It sometimes happens
• D. Only with certain metals

Answer: (B)

Oxyfuel gas cutting works by heating the metal with a flame to its ignition temperature and then blowing a jet of pure oxygen across the heated edge to oxidize the metal. The cutting action comes from this chemical reaction, not from an electric arc. Because there’s no electrical arc vaporizing metal, you don’t get the intense, frequent sparks and flying molten droplets that are common with arc or plasma cutting. The molten metal and slag are mainly formed at the cut edge and are pushed away by the oxygen jet and gravity, resulting in a relatively cleaner cut with far less sparking. There can be some light splatter if there are scale, coatings, or irregularities, but “considerable” sparking and flying molten metal isn’t typical for this process. Therefore, the statement isn’t accurate.
