In welding circuit analysis, what does open circuit voltage (OCV) represent?

In welding circuit analysis, what does open

Multiple choice — select the best answer

AThe maximum voltage during welding
BThe voltage present when no welding arc is established
CThe voltage drop across the workpiece
DThe voltage required to maintain a stable arc

✓ Correct answer: B. The voltage present when no welding arc is established Open circuit voltage is the voltage measured across the output terminals of a welding power source when no welding is taking place (no current flowing). It must be high enough to establish an arc but not excessive for safety reasons.
