1818-10 - Lincoln Electric K1818-10 LN-7 to 14-Pin Control Cable Adapter

Technical Overview of the Lincoln K1818-10 Control Cable

The Lincoln Electric K1818-10 is a specialized control cable assembly designed to bridge the technological gap between legacy wire feeding equipment and modern welding power sources. Specifically engineered for the Lincoln LN-7 series wire feeders, this 10-foot (3.0 meter) cable facilitates the necessary control signal exchange between the feeder and power sources equipped with the industry-standard 14-pin Amphenol receptacle. This adapter is critical for MRO operations seeking to modernize their power supply fleet without retiring functional, durable auxiliary equipment like the LN-7.

Technically, the cable manages the transmission of low-voltage control signals, including the contactor closure (trigger) and voltage sensing required for constant voltage (CV) welding processes. The assembly features a robust, industrial-grade outer jacket designed to withstand the harsh environments typical of heavy fabrication shops, offering resistance to oil, grease, metal shavings, and thermal cycling. The internal conductors are stranded copper, selected for flexibility and fatigue resistance during repetitive movement or repositioning of the feeder.

Installation of the K1818-10 involves connecting the 14-pin connector to the power source and terminating the opposing end to the terminal strip or connection points within the LN-7 chassis. Proper installation ensures that the wire feed speed and arc initiation are perfectly synchronized with the power source output. This component is an OEM specification part, ensuring that pinout configurations match Lincoln Electric's proprietary schematics for safe and efficient operation.
