Description

Technical Field

[0001] The utility model belongs to the technical field of electric welding wire processing, in particular to a cleaning device for electric welding wire. Background Art

[0002] The principle of grinding and cleaning the welding point of electric welding wire is mainly based on physical action and material removal principle. During the welding process, some impurities such as oxides and debris will be formed at the welding point, which will affect the welding quality.
