A welding fume collector capable of improving dedusting efficiency of welding fume and prolonging the life of the filter accordingly by allowing the air nozzle to hit a cylindrical filter as a whole while rotating an air nozzle is provided. In a welding fume collector comprising: a dust collection motor(102) installed within a housing(101) to forcibly suck air; a filter installed in front of the dust collection motor to filter welding fume contained in the sucked air; and an air pipe(103) connected to a rear portion of the air nozzle to dust off welding fume accumulated on the filter by compressed air, the welding fume collector is characterized in that: the filter comprises a flat filter(110) installed at an air inlet side of the housing, and a cylindrical filter(120) installed at an inner side of the housing; the air pipe extends to the inner side of the cylindrical filter, and the air nozzle is bent perpendicularly in a length direction of the air pipe and rotatably fixed to a free end of the air pipe such that a front end of the air nozzle is directed to the center of the inside of the cylindrical filter; and a drive motor(140) for rotating the air nozzle is installed in a way that a shaft(141) of the drive motor is connected to the air nozzle to transmit power to the air nozzle.
