K936-3 - Lincoln Electric K936-3 TIG Module Control Cable Assembly

Technical Overview of the Lincoln Electric K936-3

The Lincoln Electric K936-3 Control Cable is a critical interface component designed to integrate the Lincoln TIG Module (specifically the K930 series) with compatible Lincoln Electric power sources. This assembly is engineered to facilitate the transmission of essential control signals, including remote contactor closure and amperage control, while simultaneously providing the necessary auxiliary power to the module's electronics.

Technically, the cable assembly features a specialized configuration. On the module side, it terminates in a 9-pin connector that interfaces directly with the TIG Module's control port. On the power source side, the cable splits into two distinct connectors: a 6-pin Amphenol receptacle and a standard 115V NEMA plug. The 6-pin connector is designed to mate with the remote output of the power source, enabling the TIG module to communicate start/stop signals and output regulation commands. The 115V plug is essential for powering the internal circuitry of the TIG Module, including the high-frequency generator and gas solenoid valves, drawing power either from a wall outlet or the auxiliary power receptacle often found on industrial power sources.

Constructed to meet industrial standards, the cable utilizes high-grade conductors with robust insulation to minimize voltage drop and signal interference. In TIG welding applications, where High-Frequency (HF) start is utilized, shielding against Radio Frequency Interference (RFI) is paramount. The K936-3 is built to maintain signal integrity even in electrically noisy shop environments. This cable is the designated interconnect for setups where the power source utilizes a 6-pin remote configuration, ensuring that the advanced features of the TIG Module—such as HF starting, gas pre-flow/post-flow, and crater fill—operate in perfect synchronization with the welding arc.

Proper installation of the K936-3 is vital for the safe and effective operation of the TIG welding system. It eliminates the need for complex field wiring or splicing, providing a plug-and-play solution that adheres to Lincoln Electric's engineering specifications for equipment compatibility and safety.
