Tweco 4-MPC 400A Cable Connector Set (3/0 - 4/0)

Upgrade Your Welding Leads

Keep your welding operations running smoothly with the Tweco® Model 4-MPC Cable Connector. Whether you are extending your reach across the shop or repairing a damaged lead, this 400 Amp connector set gives you the solid connection you need. Designed for 3/0 and 4/0 welding cables, it is the industry standard for reliable power transmission.

Secure and Durable Design

Loose connections cause heat, voltage drop, and poor weld quality. The Tweco 4-MPC uses a positive cam action to lock the male and female halves together tightly, ensuring consistent current flow. The double ball-point cable screws bite into the copper strands for a mechanical hold that won't let go, even when the cable is dragged around the job site.

Built for the Welder

Tweco knows that welding gear takes a beating. That's why the 4-MPC comes with zinc-plated parts to fight off rust and corrosion. The outer covers are tough enough to handle heat and oil spills, protecting the connection inside. Plus, if you have older Tweco MBP connectors in your shop, these new MPC models will plug right in, making upgrades hassle-free.
