95801102 - Tweco MPC-R Female Panel Receptacle 9580-1102

Technical Overview: Tweco 9580-1102 MPC-R Panel Receptacle

The Tweco 9580-1102 is a premium-grade Mechanical Power Connector (MPC) designed specifically for panel-mount applications on welding power sources and distribution equipment. Known in the industry as the MPC-R, this female receptacle serves as the critical interface between the welding machine's internal power bus and external welding leads. Engineered by Tweco, a leader in arc welding accessories, this component is manufactured to rigorous standards to ensure safety, durability, and electrical efficiency in industrial environments.

Constructed from a high-purity copper alloy, the conductive body of the receptacle is designed to handle high amperage loads typical of heavy-duty MIG, TIG, and Stick welding processes. The material selection ensures low electrical resistance, which is vital for minimizing voltage drop across the connection point. Excessive resistance at the machine terminal can lead to heat generation, energy loss, and unstable arc characteristics; the Tweco MPC design mitigates these risks through precision machining and substantial contact surface area.

The receptacle features a recessed contact design housed within a durable, insulating shell. This housing is molded from high-impact, heat-resistant material capable of withstanding the harsh conditions of a welding shop, including exposure to oil, grease, UV light, and incidental spatter. The mechanical connection utilizes a cam-action or friction-fit locking principle (depending on the specific mating male connector style used), which ensures a tight, vibration-resistant bond that prevents accidental disconnection during operation. This unit is designed for straightforward installation into standard panel cutouts, secured typically with a backing nut or mounting flange system, making it an ideal OEM replacement or retrofit upgrade for aging power sources.

Maintenance and safety professionals appreciate the 9580-1102 for its reliability and compliance with industry safety standards regarding exposed live parts. By recessing the female contact, the design reduces the risk of electrical shock during setup and teardown. It is compatible with standard Tweco MPC male cable connectors, allowing for seamless integration into existing cable management systems.
