How It Works • An arc is struck between a continuously fed filler wire and the work. • The arc is protected from oxidation by a shielding gas over the weld pool.
Advantages • Welds most metals • Little or no slag • Easiest to learn • Greater speed and efficiency • Fewer Weld Defects • Welds in most positions
Disadvantages • Welding outside can be difficult • Not ideal for thick material or deep penetrating welds
