The present invention relates to a wire feeding device capable of controlling tension and, more specifically, to the wire feeding device capable of controlling tension which supplies a wire to wire piezoelectricity for automatically welding the wire to a connect with pressure while continuously maintaining a tension state of the wire. The wire feeding device capable of controlling tension according to the present invention comprises; multiple bobbin shafts which are supported to a bobbin frame built on the floor with a fixed height and combines with a bobbin in which the wire is wound; a wire guide part which is installed on the front side of the bobbin frame and supplies the wire drawn through the bobbin with a fixed length and guides the wire; a tension control part which is installed on the front side of the wire guide part and pressurizes the wire to the lower part to maintain the tension state of the wire drawn through the wire guide part; and a position sensing part which is installed on one side of the tension control part and senses the moving position of the tension control part. |
