PURPOSE: A welding wire feeder is provided to prevent the twisting or cut of a welding wire by using a gripper including a ball screw, instead of rollers. CONSTITUTION: A welding wire feeder comprises a bobbin(210), a gripper(230), and a wire guide pipe(240). The bobbin supplies a welding wire(300). The gripper is installed in a frame(220) to grip the welding wire and transfer the welding wire with the torque of a ball screw(262). The guide pipe guides the welding wire transferred by the gripper to a soldering part. |
