Tweco 4-MPC-1 Female Cable Connector Half

Reliable Connections for Your Welding Leads

When you are out on the job or deep in a fabrication project, the last thing you need is a loose cable connection causing voltage drops or arc instability. The Tweco 4-MPC-1 Female Cable Connector is the industry standard for extending and repairing heavy-duty welding leads. Designed to fit 3/0 and 4/0 cable, this connector is built to handle the rough conditions of shipyards, construction sites, and fabrication shops.

No Solder Required: Forget about lugging around a torch and solder to fix a cable. The Tweco MPC series uses a strong ball-point screw connection. Just strip your cable, insert it into the brass body, and tighten the screw with an Allen wrench. It’s that simple. The connection is tight, conductive, and ready for high-amperage welding immediately.

Built Tough: The rubber cover isn't just for looks; it protects the live connection from shorting out against your workpiece and withstands heat, oil, and being stepped on. The connector features a simple twist-lock design—plug the male end in, give it a twist, and it locks solid. You can drag your leads around the shop without worrying about them popping apart. This is the female half of the connector set, perfect for the machine side or extension cords.
