A shielding gas nozzle for metal forming includes a wire feed line being a path to feed a wire at an inclination angle &#x3b8;, a first gas ejection hole to jet a shielding gas at an angle equal to or less than the inclination angle &#x3b8;, and a second gas ejection hole to jet the shielding gas in a direction different from that of the first gas ejection hole. The first gas ejection hole jets the shielding gas toward an intersection along a direction in which the absolute value of the angle to the wire feed direction is less than 90 degrees, and the second gas ejection hole jets the shielding gas toward the intersection along a direction in which the absolute value of the angle to the wire feed direction when viewed in the direction perpendicular to the base material surface is greater than 90 degrees.

A method for manufacturing a discharge surface treatment electrode includes: a first laying of laying powder particles to form a first powder layer; and a first binding of binding some of the powder particles in the first powder layer to each other. The method further includes: a second laying of further laying the powder particles on the first powder layer in which some of the powder particles are bound to each other to form a second powder layer; and a second binding of binding some of the powder particles in the second powder layer to each other to form a stacked body of granulated particles. A region having a different porosity from another region is formed inside the stacked body.

A grip unit including holding units in each of which an upper plate is placed on a lower plate to form a V-shaped groove, a grip unit control device that can change a distance between the holding unit in a range between a distance equal to or longer than a diameter of an electrode holder with an electrode feeding mechanism and a distance equal to a diameter of an electrode, a grip unit control device moving-shaft motor that can change a height of the grip unit in a range between a height at which the holding unit are placed lower than an electrode holder brim of an electrode holder having an electrode feeding mechanism attached to an electric holder gripping device and a height to which the holding units lift up the electrode holder brim of the electrode holder having an electrode feeding mechanism attached to the electric holder gripping device, and an electrode gripping device that can grip the electrode on a lower side of the grip unit are included. In one of the pair of holding units, a portion of the upper plate which forms the V-shaped groove is placed on a front side and a portion of the lower plate is placed on a rear side so as to overlap with each other. In the other one of the pair of holding unit, a portion of the lower plate which forms the V-shaped groove is placed on the front side and the upper plate is placed on the rear side so as to overlap with each other.
