The motivation behind the idea was the need to lessen splashes and eliminate incomplete flaws of fusion. The pulsed arc process incorporated the benefits of axial spray transfer: clean, splash-free welds that have excellent fusion with less heat input. The lower average current provided by GMAW-P allowed for out-of-position welding capability with improved weld quality compared to short-circuit transfer. The GMAW process is flexible in its ability to provide sound welds for a very broad base material type and thickness range.
