MMA INSTALLATION
Arc welding is also called the MMA (Manual Arc Welding) method and is the oldest and most versatile arc
welding method.
The MMA method uses a coated electrode, consisting of a metal core covered with a lagging. An electric arc
is created between the end of the electrode and the material being welded. Arc ignition is created by
touching the electrode with the end of the workpiece. The welder feeds the electrode as it melts into the
workpiece so as to maintain a constant arc length and at the same time moves its melting end along the
welding line. The melting coating of the electrode gives off protective gases that protect the liquid metal from
the influence of the surrounding atmosphere, and then solidifies and forms a slag on the surface of the lake,
which protects the coagulating weld from cooling too quickly and harmful environmental influences.
Connect the welding and mass leads to the appropriate output connectors of the welder, according to the
polarity recommended by the manufacturer of the electrodes you intend to weld.
