K1840-10 - Lincoln Electric 1/0 Weld Power Cable Assembly, Twist Mate to Lug, 10 ft

Lincoln Electric K1840-10 Weld Power Cable Technical Overview

The Lincoln Electric K1840-10 is a premium Weld Power Cable assembly designed to facilitate high-current power transmission between welding power sources and wire feeders. Engineered for industrial reliability, this cable features a robust 1/0 AWG copper conductor, ensuring minimal voltage drop and efficient energy transfer even under heavy loads. The assembly is rated for a welding output of 350 Amps at a 60% duty cycle, making it suitable for a wide range of structural and heavy fabrication tasks.

This specific configuration is terminated with a Lincoln Electric Twist Mate™ connector on one end and a standard Lug on the other. The Twist Mate™ system allows for rapid, tool-free connection to compatible power sources, utilizing a cam-lock style mechanism that ensures a tight, high-conductivity fit that resists loosening due to vibration. The Lug end is designed for secure bolting to the input studs of wire feeders, providing a permanent and stable electrical interface.

With a length of 10 feet (3 meters), the K1840-10 offers sufficient reach to position wire feeders away from the power source without introducing excessive cable clutter. The outer jacket is composed of high-grade industrial rubber, formulated to withstand the rigors of harsh environments, including exposure to sparks, abrasion, oil, and grease. This cable is explicitly listed as an accessory for Lincoln Electric's advanced wire feeders, including the LN-25X®, LN-25X® PRO, Power Feed® 25M, and the Activ8X® Wire Feeder.

By utilizing a factory-assembled cable like the K1840-10, operators ensure compliance with electrical specifications and eliminate the variability associated with field-terminated cables. The 1/0 gauge size strikes an optimal balance between current-carrying capacity and flexibility, allowing for easier routing and handling in dynamic workshop or field environments.
