The operating voltage required for air carbon arc welding is ___________.
A) 35 volts or higher
B) 18 volts or higher
C) 120 volts or 240 volts
D) 24 volts or lower

Question

Quizplus · Accepted Answer

The operating voltage required for air carbon arc welding is typically 35 volts or higher. This high voltage is necessary to create an arc between the carbon electrode and the workpiece, which produces the heat needed to melt the metal and create a weld. Lower voltages, such as 18 volts or less, are typically too low to sustain an arc and create the necessary heat to weld effectively.
