Claims

[Scope of utility model registration request]

(1) Insert the wire into the outer circumferential surface of the wire drive roller of the wire feeding device of the welding machine ■The groove surface has a finely uneven blade surface inclined at a predetermined angle with respect to the wire feeding direction. Features: Wire drive rollers for welding machines.

(2) Utility model registration The roller according to claim (1) is a wire-driving roller for a welding machine in which the finely uneven blade surface of the groove surface is knurled.

(3) Utility model registration Claim (1) In the wire drive roller of the welding machine, the fine irregularities on the groove surface of the wire drive roller have a knurling flattened surface of 0.2 to 0.6. roller.

(4) Scope of claims for utility model registration (1), (2), (3)
The wire drive roller inserts the wire into the wire drive roller of a welding machine, which is divided into circular slices at the center of the groove, and the left and right divided parts are joined by screws, etc. roller.
