Globular Transfer

Globular transfer  is characterised by a drop size of greater diameter than that of the electrode wire. The large drop is easily acted on by gravity, generally limiting successful transfer to the flat position. Globular transfer occurs in the current range higher than that of short circuiting transfer. The arc length must be long enough to assure detachment of drop before it contacts the molten metal. CO2 shielding results in randomly directed globular transfer. The non axial transfer is due to an electromagnetic repulsive force acting upon the bottom of the molten drop.
