In CAC-A gouging setup, which component is connected to the negative terminal as part of the polarity arrangement?

• A. Ground
• B. Electrode
• C. Workpiece
• D. Power source

Answer: (A)

Polarity in CAC-A gouging establishes where the return current path is, and the negative side is tied to the ground clamp to complete the circuit safely. The ground connection provides the return path for the gouging current back to the power source, keeping the arc focused on the base metal and minimizing stray currents. The carbon electrode is connected to the opposite terminal to sustain the arc, and the power supply supplies both terminals. So, the component connected to the negative terminal is the ground.
