Home Welding Thor MMA

MA welding (metal arc) does not require shielding gas; protection for the weld pool comes from the electrode cover which melts during welding, and forms a protective layer of slag on the weld pool.It is the oldest and still the most commonly used arc welding process, although the proportion of MMA use is decreasing as gas-shielded welding process is becoming more popular.MMA welding is, however, an irreplacable method for instace when that electrodes can be bought everywhere, also in small package.
