K4269-1 - Lincoln Electric Automatic Timer Relay Upgrade Kit

Technical Overview of the Lincoln Electric K4269-1

The Lincoln Electric K4269-1 Timer Relay Kit is a specialized electromechanical accessory designed to integrate seamless timing logic into industrial welding power sources and environmental systems. As a genuine OEM component, this kit is engineered to meet the precise electrical specifications of Lincoln Electric equipment, ensuring that voltage tolerances, switching capacities, and timing intervals are perfectly matched to the host machine's control circuitry. The primary function of this relay kit is to provide a controlled time-delay action, often utilized in 'run-out' scenarios where a peripheral device—such as a cooling fan or a fume extraction motor—must continue operating for a specific duration after the welding arc is extinguished.

Technically, the K4269-1 module interfaces with the machine's trigger or arc-sensor signal. When the operator ceases welding, the relay engages a hold-circuit that maintains power to the auxiliary load for a preset or adjustable window. This is critical in fume extraction applications (like the Statiflex or Prism systems) to ensure that any residual particulate matter remaining in the extraction arm or ductwork is fully evacuated before the system powers down. The kit includes the relay unit itself, which is housed in a durable casing to resist dust and vibration common in industrial environments, along with the necessary wiring harness and mounting hardware to facilitate a secure installation within the control cabinet.

Installation of the K4269-1 requires access to the internal control panel of the welding equipment. The kit is designed for straightforward retrofit or replacement, utilizing standard terminal connections that correspond to Lincoln's wiring diagrams. By using this authentic Lincoln Electric part, maintenance personnel ensure the integrity of the equipment's warranty and safety certifications. The relay's contacts are rated for the inductive loads typical of industrial motors and solenoids, preventing premature failure due to arcing or contact welding. Whether used for upgrading a basic system to include automatic features or replacing a worn timing component, the K4269-1 offers a reliable solution for managing equipment duty cycles and operational sequences.
