Abstract

In this paper, the influence of arc current on arc modes transitions of a new AMF electrode with one-turn coil structure are investigated at long gap distance 40 mm. A CCD video camera is used to observe the arc behavior. Two groups of arc modes are featured: 1) diffuse arc modes including multi-cathode spots arc, high current diffuse arc and high current diffuse column arc; 2) constricted arc modes including anode plasma jet with local concentration of many cathode spots and group of cathode spots (APJS), anode plasma jet with local concentration of many cathode spots, anode and cathode plasma jets (APJ), and intense arc mode. The rule of arc modes transition under different amplitude of arc current is researched
