A bearing is located at the front of a frame and through means of this bearing an electrode disposed upon one side of a welding gap and an electrode disposed upon the other side of the welding gap can be positioned opposite each other upon a horizontal central axis line, so that with the electrode part upon one side of the welding gap having an electrode bit at the front thereof being movable forwardly and backwardly while connected with the bearing, an object to be welded can be gripped between the electrode bit on the one side and the electrode bit on the other side; and if the electrode on the other side which is provided with a bracket having the other electrode bit disposed at its tip, and which is attached externally to the bearing, is rotated around the electrode upon the one side, spot welding in many different positions, including upwardly, downwardly and sideways, can be easily achieved.

A spot gun for a welder machine, comprising: first electrode means mounted upon said gun and extending along a welding axis; second electrode means extending along said welding axis in a coaxially, oppositely disposed, manner with respect to said first electrode means, so as to define with said first electrode means a welding gap therebetween within which a component to be welded is to be disposed, and rotatably mounted upon said gun with respect to said first electrode means and about said welding axis so as to be selectively disposed at any one of a plurality of predetermined circumferentially spaced positions with respect to said welding axis so as to improve the accessibility of said spot gun to said component to be welded during a welding operation; and means for positively locking said second electrode means at said any one of said plurality of predetermined circumferentially spaced positions.
