What makes it possible for the oxyacetylene gouging tip to gouge, but not cut through the metal?

• A. A lower oxygen cutting pressure
• B. A smaller cutting oxygen orifice
• C. A higher flame temperature
• D. All of the above

Answer: (A)

Gouging with an oxyacetylene torch works by heating the metal and using a strong oxygen jet to blow away the molten material, but it’s done at a lower cutting oxygen pressure so the flame won’t advance to cut through. That reduced pressure prevents a through-cut while still providing enough heat and a focused jet to oxidize and lift away metal, creating a groove rather than a full cut. The other factors—changing the orifice size or raising the flame temperature—can influence flame behavior or heat, but they don’t define gouging the way lowering the cutting oxygen pressure does. With lower cutting pressure, you get the gouge without drilling through the metal.
