Modes of Metal Transfer: Pulse

Pulsed spray refers to a GMAW mode of transfer in which metal droplets are transferred through the arc with changes in amperage produced by the power source.  The power source provides a pulsing peak current that raises the amperage above the transition current and allows for axial spray transfer.  This peak current is only applied […]

Modes of Metal Transfer: Spray

Spray is a mode of metal transfer in which a fine spray of metal droplets are projected axially from the tip of the electrode to the work.  These droplets are smaller in diameter than the electrode.  This mode of transfer is characterized by high wire feed speeds (high amperage), high voltage and consequently high heat […]
