K3417-70 - Lincoln Electric Tweco-Style Female Cable Receptacle 1/0-2/0

Reliable Power Transmission with Lincoln Electric

The Lincoln Electric K3417-70 is a premium-grade Tweco-style receptacle designed to facilitate secure and efficient connections in welding power circuits. Engineered for professionals who demand reliability, this female receptacle is specifically sized to accommodate welding cables ranging from 1/0 to 2/0 AWG. In the world of industrial welding, the integrity of your electrical connections is paramount; a poor connection can lead to voltage drops, arc instability, and excessive heat generation, all of which compromise weld quality and equipment longevity. The K3417-70 addresses these concerns with a robust design that ensures maximum conductivity and mechanical stability.

Constructed from high-quality materials, this receptacle features a precision-machined brass or copper alloy body that provides a low-resistance path for welding current. This is critical for maintaining consistent arc characteristics, especially when working with long cable runs where resistance can naturally build up. The Tweco-style design is an industry standard, known for its positive cam-action locking mechanism. This feature allows the operator to connect and disconnect cables with a simple twist, ensuring a tight fit that resists loosening due to vibration or cable movement during operation. The female variant serves as the receiving end of the connection, typically mounted on the machine or used as part of an extension lead setup.

Durability is a key focus of the K3417-70. The connector is encased in a rugged insulating cover that protects the live metal components from accidental contact, moisture, oil, and physical impact. This makes it suitable for harsh industrial environments, including construction sites, shipyards, and fabrication shops. By choosing a genuine Lincoln Electric accessory, users benefit from the assurance of quality control and compatibility that comes with a leading brand in the welding industry. Whether you are setting up a new welding rig or repairing damaged leads, this receptacle provides the performance and safety required for heavy-duty applications.

Installation of the K3417-70 is straightforward, designed for quick field repairs or shop assembly. The cable connection point is engineered to grip the stripped cable strands securely, often utilizing a heavy-duty set screw or ball-point screw mechanism that ensures high pull-out strength and excellent electrical contact. This component is an essential part of any welder's inventory, ensuring that power delivery remains uninterrupted and safe.
