What is Manual Metal Arc Welding?
Manual metal arc (MMA) welding is a welding process where the electric arc burns between a coated electrode and the workpiece. The electrode is fixed in an electrode holder and touches shortly the area that is to be joined. A short circuit is produced and the arc starts when lifting the electrode. During the welding process the electrode and its coating melt and slag develops above the weld seam.
MMA welding can be applied in all welding position with th suited equipment and is an economic alternative since only few equipment is needed.
