Power cable adapter

A power cable adapter for use with a welding torch assembly to electrically couple the power cable in the cable carrying line with the power output stud on the welding machine and communicate the cable carrying line with a fluid supply line for the passage of fluid therethrough, said adapter comprising:

• a pair of electrical conductive clamp members adapted to be secured to the output stud in an adjacent disposition, each of said members defining an aperture extending therethrough, a contact surface and an open channel extending laterally across said surface whereby upon said contact surfaces being held in substantially adjacent juxtaposition, said apertures are axially aligned to define a cylindrical opening adapted to receive the output stud and said channels extend in opposed disposition perpendicular to a central is of said opening, and wherein said channels each define a constant depth of a first dimension and a constant width of a second dimension, each of said second dimensions being greater than said first dimensions;
• a fitting tube assembly including a hollow electrically conductive and substantially U-shaped tube and a pair of cable connector fittings carried by the ends of said tube, said tube being adapted to extend along said channels between said clam members and project from the ends of said channels such that upon said clamp members being urged together, said tube is in electrical contact with said clamp members and said fittings are spaced from said clamp members and aligned in parallel, one of said fittings being adapted for electrical communication with the power cable and fluid communication with said cable carrying line and the other of said connectors being adapted for fluid communication with the supply line;
• and
• a fastening member for urging said clamp members about said tube and securing said adapter on said output stud.

A power cable adapter for use with a welding torch assembly to electrically couple the power cable in the cable carrying line with the power output stud on the welding machine and communicate the cable carrying line with a fluid supply line for the passage of fluid therethrough, said adapter comprising:

• a rear clamp member adapted to be secured to the output stud on the welding machine and defining a first aperture extending through an upper portion thereof adapted to receive the output stud for securing the adapter thereon, a contact surface and an open channel extending laterally across a lower portion of said surface;
• a forward clamp member adapted to be carried by said rear clamp member in substantial adjacent juxtaposition, said forward clamp member defining a contact surface and an open channel extending laterally across a lower portion of said surface;
• a fastener assembly carried by and extending between said forward clamp member and said rear clamp member for urging said clamp members together in substantially adjacent juxtaposition such that said channels extend in opposed alignment perpendicular to a central axis extending through said first aperture in said rear clamp member;
• and
• a fitting tube assembly including a hollow electrically conductive tube and a pair of torch line connector fittings carried by the ends of said tube, said tube being adapted to extend along channels between said clamp members and project from the ends of said channels such that upon said clamp members being urged together by said fastener assembly, said tube is secured in electrical contact with said clamp members and said fittings are spaced from said clamp members, one of said fittings being adapted for electrical communication with the power cable and fluid communication with said cable carrying line and the other of said fittings being adapted for fluid communication with the fluid supply line.
