Welder Red Seal · Question
A carbon arc gouging operation is producing a very shallow and wide groove despite the welder maintaining a consistent electrode angle and travel speed. The power source is set to constant current (CC) mode. What parameter adjustment would best address this issue?
A shallow and wide groove indicates insufficient melting and metal removal. Increasing the amperage setting will increase the heat available at the arc, leading

Question: A carbon arc gouging operation is producing a very shallow and wide groove despite the welder maintaining a consistent electrode angle and travel speed. The power source is set to constant current (CC) mode. What parameter adjustment would best address this issue?
Answer options:
- Increase the air pressure
- Switch to constant voltage (CV) mode ✅ Increase the amperage setting
- Decrease the electrode diameter
Correct answer: Increase the amperage setting
Explanation: A shallow and wide groove indicates insufficient melting and metal removal. Increasing the amperage setting will increase the heat available at the arc, leading to more aggressive melting and a deeper, more effective gouge.
