The advanced electronics of the phaser mx3 makes sure that the arc is reliably ignited in the micro mode even if minimal power and time settings are chosen.
The result: Even in the lowest energy areas, needed i.e. for thin crown margin extensions, small holes or orthodontic wires, continuously identical, fine spot welds can be created. At the same time the tungsten electrode lasts longer as, due to the refined power control, an accidental pre-ignition with too much energy is no longer possible.
