PPA in welding refers to "Plasma-Powered Arc," a technique that utilizes a plasma arc to melt and fuse materials. It is often employed in high-precision applications and can be used for welding a variety of metals. The process offers advantages such as deeper penetration and improved control over the heat input, resulting in better weld quality. PPA is particularly effective for thin materials and in situations where a clean, precise weld is essential.
