The flux layer shields both the arc and molten metal from atmospheric impurities of oxygen and nitrogen. A level 10 darkness is the minimum for arc welding. Figure 1 in smaw an electric arc is used to produce the necessary heat to melt the base metal this arc is generated by striking the electrode with the workpiece. Gas regulator assembly 3.
