Abstract

PURPOSE: To reduce the size of anode while to prevent the consumption of tip portion and to achieve long service life, by employing coarse crystal structure at the tip of anode.
CONSTITUTION: The anode 3 has gradually thined tip at discharge path side while pressure engaged with wels 5 at the rear end, where the crystal structure is gradually coarsed toward the tip, the average particle diameter of orystal at the leading face is 5W6mm, for example, while 30W100μ in the proximity of end face. Consequently electron impingement resistance is improved to reduce anode consumption such as spattering thereby the arc is stabilized, service life is lengthened and the size is reduced.
