MANUAL METAL ARC (MMA) “STICK” WELDING
www.weldability-sif.comArc welding with coated electrodes is a manual process where the heat source consists of the electric arc. When the arc strikes between the coated electrode (by means of an electrode holder) and the piece to be welded (base material), it generates heat which causes rapid melting of both the base material and electrode.
