10-6128 - Tweco MPC-50-M Male Dinse Cable Connector 50mm

Technical Overview of the Tweco 10-6128 MPC-50-M

The Tweco 10-6128 (Model MPC-50-M) is a premium male cable connector utilizing the international Dinse-style 50mm tapered interface. Engineered for industrial welding environments, this connector is designed to terminate welding cables ranging from 1/0 AWG to 3/0 AWG. The core component is manufactured from a high-conductivity copper alloy, optimized to reduce electrical resistance and minimize heat generation at the connection point, ensuring consistent arc stability during high-amperage operations.

This connector features a mechanical cable fastening system, typically utilizing a set screw or ball-point design, which provides a secure mechanical and electrical bond between the cable strands and the connector body. This design facilitates easy installation and replacement in the field using standard hand tools. The connector is encased in a durable, high-dielectric rubber insulator that offers superior resistance to heat, oil, solvents, and abrasion, protecting the connection from the harsh conditions typical of fabrication shops and construction sites.

The MPC-50-M is fully compatible with standard female 50mm Dinse receptacles found on most modern welding power sources and wire feeders. The connection mechanism employs a simple push-and-twist action (approximately a half-turn) to lock the connector in place, preventing accidental disconnection while allowing for rapid setup and teardown of welding equipment. This unit is rated for heavy-duty cycles and is an essential component for maintaining efficient power delivery in MIG, TIG, and Stick welding setups.
