Open circuit voltage when no welding is performed typically falls in which range?

• A. 50-100 volts
• B. 0-10 volts
• C. 12-24 volts
• D. 150-200 volts

Answer: (A)

Open-circuit voltage is the voltage a welding power source presents when no current is flowing and no weld is being made. For common arc welding like SMAW, the no-load voltage is designed to be high enough to start the arc but safe to handle, which places it roughly in the 50 to 100-volt range. This is why the range 50-100 volts is the best fit. The other options don’t match typical welding gear: 0-10 volts is too low to strike an arc, 12-24 volts is more typical of TIG or MIG systems at lower settings, and 150-200 volts is higher than standard welding equipment for normal processes.
