Welding wire feeding device

Abstract

The present invention provides a welding wire feeding device equipped with a wire guide that eliminates the need for tools when removing the wire guide from the welding wire feeding device. [Solution] This welding wire feeding device 1 includes a housing area R1 that houses a welding wire feeding mechanism M1. The housing area R1 is provided with wire guides 500, 600 that guide the welding wire 4 by inserting the welding wire fed by the welding wire feeding mechanism. The wire guides 500, 600 are equipped with a mechanism that allows them to be attached to and detached from the housing area R1 without the use of tools. The housing area R1 includes a bottom surface 111 and walls 112, 113 that are positioned opposite to the direction in which the welding wire 4 is fed. The wire guides 500, 600 are mounted on the walls 112, 113 facing the housing area R1.
