If a technician speaks of adjusting the CV setting on a welding power supply, what are they adjusting?

Explanation:
In a constant-voltage welding power supply, the CV setting controls the arc voltage. You set the target arc voltage, and the machine maintains that voltage by automatically varying the current to keep the arc stable. So adjusting CV changes the voltage, not directly the current (current adapts to maintain that voltage). Resistance and capacitance aren’t what CV refers to in this context.
