Abstract: A hand held splicing gun for splicing together exposed portions of a number of wires. The gun includes a frame and a trigger actuated valve that routes compressed air to two drive cylinders mounted to the frame. A first cylinder drives a pair of forming bars against a strip of splicing material. Working in conjunction with a shear block and a forming post, the bars first shear a band from the splicing material and then bend the band into a U-shape about the wires. The second drive cylinder drives a crimping bar against the band, causing the band to bend around the wires, securing them together.
