Abstract
Nonconsumable electrode for melting metals and alloys, comprising a housing with a hollow fluid-cooled tip. On one of the tip's side-walls, on the side of the cavity, there is at least one threaded groove. This side wall with the threaded groove on it serves as a means for the rotation of the arc which is actuated between the tip and a metal or alloy to be melted.
