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

• A. True
• B. False
• C. It never sparks
• D. It sparks only at start

Answer: (B)

Oxyfuel cutting relies on preheating the metal and then using a jet of pure oxygen to burn it at the cut edge. The molten metal is blown out by the oxygen stream, creating a clean kerf with hot slag, rather than a heavy shower of sparks. Because the process uses combustion controlled at the cut edge rather than a high-energy arc, it does not produce the considerable sparking and flying molten metal that you’d see with plasma cutting or other arc processes. Some minor spatter or slag ejection can occur, but sparking isn’t a defining feature of oxyfuel cutting.
