When the welding is completed and the layer of slag is removed, the finished weld will be disvocered underneath.      MMA welding is the oldest and still the most commonly used arc welding process, although the proportion of MMA use is decreasing as gas-shiedled welding process is becoming more popular.      MMA welding is, however, an irreplacable method for instace when welding outside in windy conditions where using shiedling gas would be difficult. Another important benefit is that electrodes can be bought everywhere, also in small package.        PROSPER's range of MMA welding machines offers DC inverter constant-current type, AC Arc transformer type and AC/DC type machines for all user groups from home users to extensive industrial application.
