CV stands for which term?

• A. Constant voltage
• B. Constant current
• C. Calibrated voltage
• D. Cable voltage

Answer: (A)

Constant Voltage means a welding power source is set to keep the arc voltage steady, while the current varies as needed to maintain the arc. This approach is common in semi-automatic processes like MIG welding, where keeping the voltage approximately fixed helps stabilize the arc and produce a consistent bead, with current adjusting in response to changes in arc length or wire feed. The other terms aren’t standard welding-power terms: constant current is a different mode that holds current steady and lets voltage shift, while “calibrated voltage” or “cable voltage” aren’t used designations in this context.
