As shown in the figure. 1 is a welding power source, 2 is a wire feeding device, 3 is a welding torch, 4 is a shielding gas cylinder, and 5 is a welding wire. Smooth feeding of the welding wire 5 by the wire feeding device 2 is one of the major factors affecting arc stability, and micro vibrations of the wire spool are also a factor.

This will be explained along the diagram. 6 is a wire feeding motor 7
It is a frame body to which a spool shaft 8 is attached. The welding wire 5 held on the spool shaft 8 passes through a feed roller 9 attached to the output shaft of a wire feeding motor 7 and a feed roller 12 attached to a pressure arm 11 which is pressurized by a pressure nut 10. is sent to the torch 3 by the

ぼしている。 The spool shaft 8 is formed into a cylindrical shape as shown in FIG. 3, and is fixed to the frame body 6 with bolts. The outer diameter D S of the spool shaft 8 is smaller than the inner diameter D W of the welding wire spool 5, and D W −D S is about 0.5 to 1.5 mm. The welding wire spool 5 rotates around a fixed spool shaft 8. That is, the contact point between the welding wire spool 5 and the spool shaft 8 in a stationary state when viewed from the side is A in FIG.
However, the movement of this point A causes vibration of the wire spool, which affects the stability of the arc.

することに起因するものである。 FIG. 5 shows the state of contact between the spool shaft 8 and the welding wire spool 5. The stationary contact point A moves to point B due to frictional force as the wire feeds (in the P direction), that is, the welding wire spool 5 rotates. Also, at point B, the weight of the welding wire spool 5 overcomes the frictional force, and instantaneously
Move from point to point A. However, because of inertia, it passes point A and moves to point C. FIG. 6 shows such movement of the contact point on the spool shaft. The repetition of such operations generates vibrations during rotation, which prevents the welding wire spool 5 from rotating smoothly. This condition becomes more noticeable as the remaining amount of welding wire decreases and the weight of the wire spool itself decreases. This is due to the fact that the welding wire spool 5 is supported by a line passing through the apex on the circumference of the spool shaft 8.

FIG. 8 shows a spool shaft 13' (another embodiment) with a cutout 13b. In this embodiment, two-point support is maintained even during rotation due to the weight of the welding wire spool 5, and the support points D and E do not move, compared to the conventional support at the apex of the spool shaft circumference.
