PURPOSE: To set the adequate aiming angle for fillet welding corresponding to an angle of inclination by supporting a distributing arm to one end of an air cylinder block and connecting the other end and a suspension bracket via a link mechanism.
CONSTITUTION: A feed rod 3 for welding moves by turning to the position on the line rotated by as much as the angle of inclination from an aiming weld line position 2 as said rod inclines around an inclining and turning shaft 1 of a conveying and distributing device. The connecting and supporting pin 6 of an air cylinder block 8 is positioned on approximately the bisector of a set angle α of inclination by an adequate lever ratio between a bracket 4a and correcting bracket 4b as well as an intermediate crank rod 5a pinning one end thereof. The extruded shaft of the block 8 is further matched approximately with the bisector of the set angle α by the tail supporting effect of a spring rod 7a, by which the adequate torch angle aiming the weld line position 2 and the torch aiming position are automatically determined.
