Answer: Half-round electrodes are designed for cutting wide grooves with torches designed for smaller electrodes and cutting material thicker than 2" (51 mm). They are used for close-tolerance metal removal such as beveling and are typically used in continuous-feed equipment.
Half-round electrodes are typically used in plasma arc cutting, which is a process that uses a plasma torch to cut through conductive materials such as steel, aluminum, and copper. The half-round shape of the electrode allows for a wider and deeper cut than a traditional electrode, making it ideal for cutting thick materials or creating wide grooves. They are also used for beveling, as they can make cuts at an angle, which is useful for creating a chamfer or beveled edge on a piece of metal.
