What is manual metal arc gouging?


Manual metal arc or shielded metal arc (MMA or SMA) gouging is similar to other gouging operations, such as carbon arc, where the metal is melted by the arc and removed by focused air blast. Many materials may be gouged by this process, but with manual operation, the quality of the cut is rather rough and uneven. However, it is particularly suited to site applications where other, more sophisticated techniques may not be available.
