What is a Constant Voltage Power Source in Welding?

A constant voltage power source (CVPS) is an arc welding power source that produces a large welding current change from a small arc voltage change. This makes it ideal for welding metals with high melting points, such as aluminum and stainless steel.

CVPSs are also known as “inverters” because they convert direct current (DC) into alternating current (AC). This AC current can be either sinusoidal or nonsinusoidal. Nonsinusoidal AC is sometimes called a “square wave” because it has sharp rising and falling edges.

What is the advantage of using a constant voltage power source welding?

The advantage of using a CVPS for welding is that it provides stable arc welding current and voltage. This results in fewer weld defects, less rework, and less downtime. CVPSs are also more energy-efficient than traditional AC or DC power sources, making them more environmentally friendly.

What is a constant voltage power supply?

A constant voltage power supply (CVPS) is an electrical device that provides a regulated DC voltage. The output voltage of a CVPS remains constant even if the load current or input AC voltage changes.

What is constant current and constant voltage in welding?

In welding, constant current (CC) and constant voltage (CV) refer to the two most common types of arc welding power sources. CC power sources provide a constant welding current, while CV power sources provide a constant welding voltage.
