ABSTRACT:
A nonconsumable electrode comprises a hollow cylindrical body, a hollow detachable tip made in the form of a body of revolution coaxial with the hollow cylindrical body, a solenoid for generating a magnetic field, and a partition. The tip is secured to one of the ends of the body and has lateral cylindrical non-arcing portion and a convex arcing end portion. The lower end of the solenoid is disposed in the tip cavity defined by the cylindrical non-arcing portion of the tip. The partition is coaxially mounted in the cavity of the body and of the tip so that between said partition and the walls of the body and of the tip there is formed a passageway for the flow of a coolant.
