Abstract
An arc welder cable includes a resiliently flexible hose, an intermediate sheath, a plurality of conductors, and an outer sheath. The hose defines an axial passageway configured to permit passage of a welding wire and a shielding gas therethrough. The intermediate sheath circumscribes the hose such that the hose is disposed radially within the intermediate sheath. The intermediate sheath is made from an electrically-insulative material and is in sealing contact with an outer surface of the hose. The conductors are disposed circumferentially about the intermediate sheath and disposed radially outward of the intermediate sheath. The conductors extend along the intermediate sheath in a helical manner. The conductors are made from an electrically-conductive material. The outer sheath is made from an electrically-insulative material and circumscribes the conductors such that the conductors, the intermediate sheath, and the hose are disposed radially within the outer sheath.
