The blowing device is set near a front side of the metal wire and has a first guiding block and a first air source. The suction device is set near a rear side of the metal wire and has a second guiding block and a second air source. The tension device is set between the blow and suction devices. The fuse device is set near a left side of the metal Wire and has a pressure pump and a fused head. The transporting pipe is set above the suction device and aligns with the suction device to receive the fused metal wire.
