<p>PROBLEM TO BE SOLVED: To provide a conduit cable 21 which inhibits breaking of a conductor 26 and enables improvement of the operability of a welding torch 8.SOLUTION: A conduit cable 21 of the invention includes: a coil liner 24 which guides a welding wire 12 delivered from a welding wire delivery machine 7 to a welding torch 8; a conductor 26 which supplies electric power; and an outer sheath 22 which covers the coil liner 24 and the conductor 26. A coil liner insertion hole 23 is formed in a longitudinal axis direction of the outer sheath 22 and the coil liner 24 is inserted into the coil liner insertion hole 23. A conductor insertion hole 25 is formed in the longitudinal axis direction of the outer sheath 22 and the conductor 26 is inserted into the conductor insertion hole 25. A space, in which the conductor 26 may move, is provided between an outer peripheral surface of the conductor 26 and an inner peripheral surface of the conductor insertion hole 25. As a result, the conductor 26 may move relative to an external force applied to the conduit cable 21.</p> |
