Abstract

The outer shell of the linking housing (7) of the welding machine consists of a first casing (7a) and a second casing (7b), assembled together through a flat surface (44). The electrode support (10) is mounted to move in rotation in a bearing (30) fixed in the first casing (7a) about an axis of rotation (42). The shaft (40) for transmission of the rotation to the electrode support (10) is mounted to move in rotation in a bearing (28) fixed in the second casing (7b) about an axis of rotation (43). The axes (42) and (43) converge at a point 0 on the surface (44) and form an angle with the axis normal to the surface (44) at 0. The disalignment of the axes (42) and (43) can be adjusted by rotating the casings (7a, 7b) with respect to each other.
