The reduction gear mechanisms of electrode wire feed with roller motors, widely used in mechanized arc welding equipment, are analyzed. It is shown that with the increase of the feed roller diameter the values of tractive characteristics of the mechanism become higher, service life is extended and losses in the roller feed unit are reduced. A design of the feed roller is given characterized by a unrestrained mounting of the feeding element on the driving element. This provides the invariance of the electrode wire feed rate to its diameter, fast mounting and dismantling of the feed roller in the case of its replacement.
