Abstract
A welding cable is described in which a welding current conductor, switch wires and a gas conductor tube are all contained in longitudinal passages in a single cable jacket. The passages containing the gas conductor tube and the switch wires are accessible through longitudinal openings in the jacket coextensive with the passages to facilitate insertion and removal of the switch wires and the gas conductor tube.
Claims9
A welding cable comprising, a cable jacket having a first longitudinal passage therein, a welding current conductor disposed in said first longitudinal passage, said cable jacket having second and third longitudinal passages therein, switch wire means and a gas conductor tube disposed in said second and third longitudinal passages, said cable jacket including longitudinal openings therein coextensive with said second and third longitudinal passages communicating therefrom to the exterior of said jacket to facilitate insertion and removal of said switch wire means and said gas conductor tube from said cable jacket.
A welding cable comprising, a cable jacket having a first longitudinal passage therein, a welding current conductor disposed in said first longitudinal passage, said welding current conductor being of annular cross section and defining a passage for welding electrode wire, said cable jacket having a second longitudinal passage therein, a gas conductor tube disposed in said second longitudinal passage, said cable jacket having third and fourth longitudinal passages therein positioned on opposite sides of the region between said first and second longitudinal passages, a pair of switch wires, one in each of said third and fourth longitudinal passages, said cable jacket including longitudinal openings therein coextensive with said second, third and fourth longitudinal passages communicating therefrom to the exterior of said jacket to facilitate insertion and removal of said switch wires and said gas conductor tube from said cable jacket.
