The invention relates to a wire feeding / drawing device and a method thereof, which are used for feeding gold wires to a wire-welding machine. The wire feeding / drawing device comprises an electric motor component, a coil rack component and a conducting wire component, wherein a gold wire coil is assembled on the coil rack component; and a gold wire can pass through the conducting wire component. The conducting wire component comprises at least one air nozzle component, an upper wire-passing plate and a lower wire-passing plate matched with the upper wire-passing plate, wherein a gap is reserved between the upper wire-passing plate and the lower wire-passing plate; and an air nozzle faces the gap. The electric motor component drives the coil rack component to release the gold wire, and the gold wire passes through the gap and reaches the wire-welding machine. As the gold wire is light, the releasing stress equilibrium of the gold wire is disturbed, and the blowing of the air nozzle component of the conducting wire component can ensure that the gold wire in the gap can quickly and automatically achieve stress equilibrium so as to maintain the feeding track of the gold wire. Meanwhile, by adjusting the air flow of the air nozzle component, the tension of the gold wire can be controlled, thereby solving the problems of the scratch, deformation and even breakage of the gold wire andimproving the smoothness of wire feeding and the efficiency of welding.
