AI Technical Summary
Technical Problem
Welding wire debris accumulates around the drive and pressure rollers, creating conductive paths that can cause short circuits in the drive motor, leading to unexpected current flow.
Method used
A welding wire feeding device with a housing that includes a drive roller, pressure roller, and a drive motor, featuring a motor insulating bracket, disc-shaped insulating washer, and a C-shaped gap or 'labyrinth structure' to prevent welding wire debris from entering the drive motor.
Benefits of technology
The device effectively prevents the formation of unexpected current paths in the drive motor, reducing the risk of short circuits by doubling the distance of the short-circuit path and suppressing welding wire debris intrusion.

Abstract
The present invention provides a welding wire feeding device that has a configuration to avoid the formation of unexpected current paths in the drive motor. [Solution] The welding wire feeding device 1 has a drive shaft hole 111h on its bottom surface 111 through which the drive rotating shaft 701 passes, and a motor insulating bracket 710 is attached to the drive shaft hole 111h. An insulating washer 740 having a disc shape is attached to the drive rotating shaft 701 on the side of the drive roller 400, and a welding wire debris intrusion suppression structure Y1 is provided between the motor insulating bracket 710 and the insulating washer 740 to suppress the intrusion of welding wire debris generated in the welding wire feeding mechanism M1 into the drive motor 700.
