96051105 - Tweco 1-MPC Mechanical Cable Splicer for #4 - 1/0 Cable

Technical Overview of the Tweco 1-MPC Cable Splicer

The Tweco 9605-1105, designated as model 1-MPC, is a high-performance mechanical cable splicer engineered for the secure joining of welding power cables. Designed to accommodate cable sizes ranging from #4 AWG to 1/0 AWG, this component is an essential element in the maintenance and fabrication of welding circuit assemblies. The splicer is manufactured from a specialized copper alloy, selected for its excellent electrical conductivity and resistance to thermal deformation under high-amperage loads. This ensures that the splice does not become a point of high resistance in the welding circuit, thereby maintaining arc stability and machine efficiency.

A defining feature of the 1-MPC is its mechanical fastening system. Unlike crimp connectors that require specialized hydraulic tools, or soldered connections that demand heat and flux, the 1-MPC utilizes a dual ball-point screw mechanism. These screws are designed to apply high compressive force to the cable strands. The ball-point tip allows the screw to rotate against the strands without cutting or shearing them, a common failure mode in standard flat-point screws. This design maximizes the contact surface area between the cable and the connector body, ensuring optimal current transfer.

The unit is designed for durability and reusability. In industrial MRO (Maintenance, Repair, and Operations) settings, the ability to quickly repair a severed cable or extend a lead without specialized equipment is invaluable. The 1-MPC facilitates these operations with nothing more than a standard Allen wrench (hex key). While the unit provides the mechanical and electrical connection, it is typically used in conjunction with a rubber or fiber cover (sold separately) to provide electrical insulation and environmental protection. The 9605-1105 represents the metal connector body and screws, providing a robust solution for heavy-duty welding applications.
