A welding wire dispenser for use on a spool of welding wire comprising a base which is removably secured to the top plate of the spool. A let-off arm is rotatably mounted on the base and has a guide tube mounted thereon through which the welding wire extends. A brake is provided on the base and is associated with a coil spring to tension or compress the same as the welder or wire feeder pulls the wire from the spool of wire. When the welder or wire feeder discontinues its pulling action on the wire, the tension in the spring exerts sufficient force on the wire extending from the spool to prevent the wire from shingleing.
