K2485-2 - Lincoln Electric 2/0 Weld Cable Extension, 50 ft, 350A, Tweco Connectors

Industrial Grade Power Transmission

The Lincoln Electric K2485-2 is a premium Weld Cable Extension designed to bridge the gap between your power source and the workpiece in demanding industrial environments. Engineered with a substantial 2/0 AWG cross-section, this cable is optimized to minimize voltage drop over its 50-foot (15.3 m) length, ensuring that the arc characteristics remain stable and consistent even at a distance. The assembly is rated for a current capacity of 350 Amps at a 60% duty cycle, making it robust enough for heavy structural fabrication, shipbuilding, and pressure vessel welding where sustained high-amperage output is required.

Connectivity and Compatibility

Efficiency in setup is critical for MRO and fabrication workflows. The K2485-2 comes pre-terminated with Lincoln Electric's LC40 connectors, which are fully compatible with standard Tweco-style twist-lock connections. This male-and-female configuration allows the cable to serve immediately as an extension cord for existing leads, enabling operators to daisy-chain cables for extended reach without requiring tools or field splicing. The connectors are designed for high conductivity and secure mechanical locking to prevent accidental disconnection during movement.

Durability and Construction

Constructed to withstand the rigors of the job site, the cable features a durable, high-grade jacket that offers excellent resistance to abrasion, cuts, and tears. It is also formulated to resist degradation from exposure to oils, grease, and common industrial chemicals found in petrochemical and maintenance facilities. Despite its rugged exterior and heavy gauge, the cable maintains flexibility, allowing for easy routing around obstacles and convenient coiling for storage. This balance of protection and handling makes the K2485-2 an essential asset for professionals in the railroad, pipeline, and general construction industries.
