Which setting best describes gouging with an oxyacetylene torch compared to cutting through 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 relies on a different balance of the gas settings than cutting does. When gouging, you want the oxygen jet to act more as a blast that erodes and blows away molten metal rather than drive a clean through-cut. Using a lower oxygen cutting pressure achieves this by reducing the cutting action of the flame while still maintaining enough heat in the preheat zone to keep metal molten. The result is a controlled removal of material through slag blowout rather than a focused cut. The other adjustments aren’t the defining change for gouging. The orifice size for the cutting oxygen is typically not the primary factor you adjust to gouge; and a higher flame temperature isn’t the goal here—gouging isn’t about making a hotter cut, but about creating a slag-producing, blown-away metal effect.
