What is correct about shielded metal arc welding?

Its main advantage over other arc welding processes is its high productivity, considering that the electrode change in the electrode holder is very fast.
Its main advantage over other welding processes is the low heat input, which minimizes the distortion of the parts being welded.
It is a process that uses a consumable electrode coated with a flux that melts and forms a protective gas shield around the weld pool.
It is a process that uses a non-consumable electrode made of tungsten and an inert gas shield to protect the weld pool.
It is a process that uses a consumable electrode in the form of a metal wire, which is added to the weld bead.
