ABSTRACT:
A welding nozzle cleaning device includes a rotary hub and a plurality of flexible arms that extend outwardly from the hub. Each arm is formed of flexible resilient material and has an impact head at its distal end, the head being carried by the hub-and-arm assembly through a circular path of travel. As a welding nozzle to be cleaned is moved toward the cleaning device, the nozzle actuates a valve so as to provide pressurized air to the cleaning device, driving the head in the circular path, and to the welding nozzle, to blow dislodged material out of the nozzle. The arm is tubular and is bent so that its distal end defines an exhaust port that extends tangentially relative to the hub axis so that pressurized air passing through arm and out of the exhaust port drives the arms and hub about the hub axis.
