If a technician mentions adjusting CV to stabilize output, what property is being stabilized?

• A. Voltage
• B. Current
• C. Power
• D. Frequency

Answer: (A)

In constant voltage mode, the power supply holds the output voltage at a fixed value. In welding, that means the arc voltage stays roughly the same even if the arc length or load changes. The current will automatically vary to keep that voltage steady, which stabilizes the arc length and the welding process overall. So the property being stabilized is voltage. Current isn’t held constant in this mode; it changes with the load. Power can fluctuate because it depends on both voltage and current, and frequency isn’t the target of CV in DC welding.
