K867 - Lincoln Electric K867 14-Pin Universal Adapter Plug with Stripped Leads

Technical Overview of the Lincoln Electric K867

The Lincoln Electric K867 Universal Adapter Plug is a specialized interface component designed to facilitate the electrical connection between a welding power source and external auxiliary equipment. This adapter is engineered to bridge the gap between the machine's internal control circuitry—specifically the output contactor and auxiliary power circuits—and compatible accessories or wire feeders that require hard-wired integration. It is an essential component for technicians and fabricators customizing welding cells or retrofitting equipment where standard plug-and-play cables are not applicable.

At the core of the K867 is a high-quality 14-pin MS-type (Amphenol) connector. This circular connector is the industry standard for heavy-duty welding equipment, ensuring a secure, vibration-resistant mechanical and electrical connection to the power source's receptacle. The 14-pin configuration carries vital control signals, including contactor closure triggers and auxiliary power supply lines (typically 115V or 42V AC, depending on the host machine's specifications). By utilizing this standardized connector, the adapter maintains the integrity of the machine's IP rating and prevents accidental disconnection during operation.

Extending from the Amphenol connector are 8-inch (203mm) flying leads. These leads come pre-stripped, allowing for immediate termination into terminal blocks, splice connectors, or custom control panels. This design provides the flexibility required for diverse industrial applications, enabling users to adapt the power source to non-standard wire feeders, remote control pendants, or automated system interfaces. The use of the K867 ensures that all connections to the machine's sensitive control board are made through the proper designated pathways, reducing the risk of electrical noise interference or damage to the power source's internal components.

This adapter is particularly valuable in MRO (Maintenance, Repair, and Operations) scenarios where legacy equipment is being paired with modern accessories, or where a shop requires a specific pinout configuration that differs from stock cable assemblies. As a genuine Lincoln Electric part, it guarantees compatibility with the mating receptacles found on a wide range of Lincoln industrial power sources.
