K1797-25 - Lincoln Electric 14-Pin Control Cable Extension 25ft

Lincoln Electric K1797-25: 25ft Control Cable Extension

The Lincoln Electric K1797-25 Control Cable Extension is a high-performance accessory designed to extend the working distance between compatible Lincoln Electric power sources and wire feeders. Measuring 25 feet (7.6 meters) in length, this cable assembly is critical for applications requiring the separation of the wire drive unit from the welding power supply. It is equipped with industry-standard 14-pin Amphenol-style connectors (one male, one female), ensuring a direct, plug-and-play fit for a wide range of Lincoln equipment.

Technical Compatibility and Performance

This extension cable is specifically engineered for use with Lincoln Electric's semi-automatic wire feeding systems. It is fully compatible with the LN-15, LF-72, LF-74, Flex Feed series, and the LN-25 PRO Dual Power models. The cable carries all necessary control signals, including contactor closure (trigger) and remote voltage sensing/control, depending on the specific pinout utilized by the connected machine. The internal conductors are sized to minimize resistance, ensuring that control signals remain strong and accurate over the extended distance, which is vital for maintaining arc stability and consistent wire feeding performance.

Rugged Construction for Heavy Duty Use

Designed for harsh industrial environments, the K1797-25 features a durable outer sheath that protects the internal conductors from physical damage. The jacket is formulated to resist impact, tearing, and environmental contaminants found in welding shops, such as grease and metal shavings. The connectors are molded and strain-relieved to prevent cable pull-out and damage at the termination points, a common failure mode in inferior cables. This attention to detail ensures that the cable can withstand the daily abuse of being dragged across concrete floors and around steel structures.

For welders requiring even greater reach, multiple cables can often be daisy-chained, though users should verify the maximum recommended control cable length for their specific power source to avoid signal attenuation. This product is an indispensable tool for shipyard welding, large-scale fabrication, and field maintenance where equipment mobility is restricted. Invest in genuine Lincoln Electric parts to ensure the longevity and performance of your welding system.
