K1759-70 - Lincoln Electric Twist Mate Female Cable Connector 50-70mm²

Reliable Power Transmission with Lincoln Electric Twist Mate

The Lincoln Electric K1759-70 Twist Mate Female Receptacle is an essential component for professional welders demanding secure and efficient power transmission. Designed specifically for 1/0 to 2/0 AWG (50-70 mm²) welding cables, this connector ensures that your welding machine delivers its full potential to the arc without significant voltage drop or resistance heating. In the world of industrial welding, the integrity of your cable connections is just as critical as the power source itself; a loose or inferior connector can lead to arcing, overheating, and inconsistent weld quality.

This receptacle features Lincoln's renowned Twist Mate™ technology, which utilizes a DINSE-style locking mechanism. This design allows for rapid connection and disconnection with a simple quarter-turn, locking the cables securely in place. This is particularly advantageous in dynamic workshop environments or field sites where cables need to be extended, re-routed, or stored frequently. The K1759-70 is rated for a substantial 350 Amps, making it suitable for a wide range of medium-to-heavy duty welding applications, including structural fabrication, maintenance, and repair.

Durability is a hallmark of Lincoln Electric products, and this connector is no exception. The conductive components are housed within a rugged, high-quality rubber insulator that resists oil, grease, abrasion, and impact. This protective sleeve not only ensures the longevity of the connector but also provides essential electrical insulation for operator safety. Whether you are building custom welding lead extensions or replacing worn-out connectors on existing equipment, the K1759-70 provides a factory-grade fit and finish.

Proper installation of the K1759-70 is straightforward, typically involving a set-screw or crimp connection (depending on the specific internal mechanics of the revision) that bites firmly into the copper strands of your welding cable. By maintaining a tight mechanical and electrical bond, the connector minimizes resistance, thereby keeping the joint cool even during long duty cycles. Trust Lincoln Electric to keep your arc stable and your operations running smoothly.
