K1803-3 - Lincoln Electric Work Lead Assembly 2/0 Cable 350A with Dinse Connector

Lincoln Electric K1803-3 Work Lead Assembly Overview

The Lincoln Electric K1803-3 is a comprehensive Work Lead Package designed to provide a reliable electrical return path for industrial welding operations. This assembly is engineered to meet the rigorous demands of heavy fabrication, construction, and maintenance environments where consistent current flow and durability are paramount. The package comes fully assembled, featuring a 15-foot (4.5 meter) length of high-quality 2/0 AWG welding cable, which offers a balance of flexibility and current-carrying capacity.

At the core of this assembly's performance is its amperage rating. It is rated for 350 Amps at a 60% duty cycle, making it suitable for a wide range of stick, TIG, and MIG welding processes. The cable itself is terminated with a Twist Mate™ (Dinse style) connector on the machine end. Specifically, this is a 50mm male connector, designed to mate securely with standard 50mm female receptacles found on many Lincoln Electric power sources and compatible industry-standard machines. The Twist Mate system ensures a tool-free, high-conductivity connection that resists loosening during operation.

On the workpiece end, the assembly includes the GC500 Ground Clamp. This heavy-duty clamp is rated for up to 500 Amps, providing a safety margin above the cable's continuous rating. The clamp features a strong spring mechanism and large contact surface area to minimize electrical resistance at the connection point, reducing heat buildup and ensuring arc stability. The 2/0 cable is insulated with a durable jacket resistant to oil, grease, and abrasion, ensuring longevity even in harsh shop conditions. This pre-configured package simplifies procurement and setup, offering a plug-and-play solution for welders requiring a robust ground connection.
