What is another term commonly used for Constant Voltage in welding?

Constant Voltage in welding is often referred to as Constant Potential. This terminology is used because, in a constant voltage system, the output voltage remains relatively stable regardless of the changes in the welding arc length or current. This design allows for a more consistent and controlled welding process, particularly important in applications like wire feed welding processes, such as MIG (Metal Inert Gas) welding.

In these systems, maintaining a constant potential helps to ensure that the arc is easy to establish and maintain, resulting in better arc stability and a more uniform weld quality. The term "Constant Potential" aligns well with the concept of a fixed voltage that does not fluctuate significantly during the welding process, making it an appropriate descriptor in the context of welding terminology.

Other terms related to welding voltage, such as "Fixed Voltage" or "Steady Voltage," while they may convey similar ideas, do not specifically capture the concept of maintaining a constant output in the same way that "Constant Potential" does. "Constant Capacity" also does not apply in this context, as it refers to different aspects of electrical circuits or power systems.
