Abstract

PURPOSE: To apply sufficient wire feeding force and eliminate the need for exchanging feed rollers when the diameter of a wire is changed by forming the outside circumference of said feed rollers into a V-shaped face.
CONSTITUTION: Two or a number of pieces of feed rollers which are positioned by assuming a certain angle to the axis of an electrode wire which does not revolve around the electrode wire resolve while pressing the same, thereby feeding the wire toward a welding torch. The outside circumferences of these rollers are formed to have a V-shaped face of an angle α. Usually the angle α is set at 175W179.5°. Then, the feed rollers 2' and the cylindrical body of the wire 1 contact always at two points, so that large wire feed force is obtained.
