Question: When performing carbon arc gouging, which factor primarily controls the depth and width of the gouge?
Answer options:
- Electrode composition and diameter. ✅ Air pressure and electrode angle.
- Arc voltage and power source type.
- Current setting and travel speed.
Correct answer: Air pressure and electrode angle.
Explanation: The depth and width of a carbon arc gouge are primarily controlled by the air pressure, which removes the molten metal, and the electrode angle, which dictates the penetration and shape of the groove. While current and travel speed also play a role, air pressure and electrode angle are direct determinants of the gouge profile.
