Cerium Tungsten Electrode Arc Performance

Under the same experimental conditions (with the same diameter) conditions, and the comparison of the arc performance between cerium tungsten electrode and tungsten thorium electrode is shown as below:

(1) Cathode spot
Cathode spot is associated with the life of the cathode spot; the comparative experiment of the two electrodes shows that, the cathode spot of cerium tungsten electrode’s tip electrode of is the smallest, so its loss is minimal, and therefore its life is longer than tungsten thorium electrode (the influence of organizational structure).

(2) Cathode voltage drop
2% Cerium - Tungsten 12.0 volts
2% thorium - tungsten 13.0 volts

(3) Electrode emission current density
Cerium tungsten electrode’s emission current density is higher than tungsten thorium electrode and its arc is bright and narrow.

(4) Minimum arc voltage
Under the same conditions, thorium tungsten electrode’s arc voltage electrode is: 30 V; whereas cerium tungsten electrode is 12 volts.

(5) Minimum stable arc current
In large diameter, both electrodes have minimum stable arc current, with the decrease of diameter, cerium tungsten electrode have a preferably arc current performance.
