Process principle
METAL TRANSFER MODE
The filler metal is transferred by an
electric arc between the core wire
of the coated electrode and the work
piece.
Metal core wire The heat emitted by the electric arc
Crater Coating simultaneously melts the base metal
Penetration of Slag Protective (work piece), the metal core wire and
the weld bead atmosphere Metallic drops the coating of the electrode, thus

the arc

and slag transferred into the plasma
Workpiece Weld bead Molten pool of the arc.
Constituents of the electrode coating
are volatilised, thus helping
to create the arc atmosphere.
The low-density melted coating
covers the weld pool and forms the
slag that protects the deposited
metal during and after solidification.
