An electrode wire feeder includes a feed mechanism which operates from the electric motor and pulling rollers, and straightening rolls fixed on a housing in pairs relative to vertical axis with possibility of rotation. The housing is made in the form of two laths: upper and lower, in this case on the upper lath of housing the straightening rolls are fixed, and on the lower lath of housing, under pulling rollers, additional straightening rolls are fixed. In the bosses of the rollers installed into the longitudinal grooves a through threaded opening is made along the axis, perpendicular to the axis of the roller. In the upper and lower laths of housing along the axis of each longitudinal groove is made an open-end hole for approach of adjusting screw into the through threaded opening of the roller boss installed into the longitudinal groove.
