Reliable Power Connections with Lincoln Electric

The Lincoln Electric K3417-90 is a premium-grade Tweco Style Receptacle designed to facilitate secure and efficient power transmission in professional welding setups. Engineered to accommodate heavy-duty welding cables sized between 3/0 and 4/0 AWG, this female receptacle is an essential component for welders requiring reliable extensions or machine connections. In the demanding world of industrial fabrication, the integrity of your electrical connections is paramount; a loose or inferior connector can lead to dangerous overheating, voltage drops, and inconsistent arc performance. Lincoln Electric addresses these concerns with a connector built to exacting standards.

This specific model features the classic Tweco-style interface, recognized globally for its durability and ease of use. The "female" receptacle design allows it to mate perfectly with corresponding male Tweco-style plugs, creating a positive lock that resists accidental disconnection during operation. Whether you are setting up a new welding station, repairing damaged leads, or extending your reach across a large workshop, the K3417-90 provides the mechanical strength and electrical conductivity necessary for high-amperage applications.

Installation of the K3417-90 is straightforward, allowing maintenance personnel and welders to quickly assemble cables without specialized tooling beyond standard hex keys or crimping tools typically associated with this style of connector. The robust housing protects the internal copper components from physical impact, abrasion, and the grime typical of welding environments. By maintaining a tight connection, this receptacle helps preserve the life of your welding machine and ensures that the full power output reaches the arc, resulting in cleaner welds and better penetration.

Choosing genuine Lincoln Electric accessories or high-quality compatible parts like this Tweco-style receptacle ensures compatibility and safety. For operations utilizing 3/0 or 4/0 cable, which are generally employed for higher amperage stick, MIG, or TIG welding, the K3417-90 is the logical choice for maintaining a safe and efficient electrical circuit.
