Lincoln Electric Twist Mate Female Cable Connector 50-70mm²

Secure Connections for Professional Welding Leads

Upgrade your welding setup with the Lincoln Electric K1759-70 Twist Mate Female Receptacle, a premium cable connector engineered for performance and longevity. When you are out in the field or deep in a fabrication project, the last thing you need is a faulty cable connection interrupting your workflow. This female receptacle is designed to mate perfectly with compatible male Twist Mate plugs, allowing you to create reliable cable extensions or repair damaged leads on your 1/0 to 2/0 AWG (50-70 mm²) cables.

The K1759-70 boasts a robust 350 Amp capacity, providing ample overhead for most stick and MIG welding processes utilizing cables in the 50-70mm² range. The connector utilizes the industry-standard DINSE-style interface, known for its "Twist Mate" action. This quick-connect system is superior to old-fashioned lug and nut connections because it allows for tool-free assembly and disassembly of cable lengths. With a quick twist, the cam-action pulls the mating surfaces together tightly, ensuring maximum surface contact area for optimal current flow.

Built for the Shop and the Field

Welding environments are harsh, and your equipment needs to withstand the abuse. The K1759-70 features a heavy-duty insulating boot that protects the brass or copper alloy internal components from physical damage. This rubberized exterior provides excellent grip, even when wearing welding gloves, and shields the connection from shop contaminants like metal dust, sparks, and moisture. The 70mm size profile is standard across many Lincoln Electric power sources, making this a versatile part to keep in your maintenance inventory.

Using the correct connector size for your cable is vital for safety and performance. This unit is specifically calibrated for the diameter of 1/0 and 2/0 cables, ensuring a snug fit that prevents cable pull-out. By choosing genuine Lincoln Electric accessories, you are investing in the consistency of your welding arc. Poor connections are a leading cause of erratic arc starts and spatter; eliminate these variables with the K1759-70 Twist Mate Receptacle.
