K2485-3 - Lincoln Electric 3/0 Weld Cable Extension with Tweco Connectors, 50 ft

Heavy-Duty Industrial Power Transmission

The Lincoln Electric K2485-3 is a premium-grade welding cable extension designed to meet the rigorous demands of heavy industrial environments. Engineered with high-quality 3/0 AWG copper stranding, this cable ensures optimal conductivity and minimal voltage drop over its 50-foot (15.3 meter) length. It is specifically rated to handle high-output welding processes, boasting a capacity of 600 Amps at a 60% duty cycle. This makes it an essential component for structural fabrication, shipbuilding, and heavy equipment repair where power consistency is critical.

Robust Connectivity and Durability

Equipped with industry-standard Tweco-style male and female connectors, the K2485-3 offers reliable, positive-locking connections that resist accidental disconnection during operation. The connectors are factory-installed to ensure a secure mechanical and electrical bond, reducing resistance and heat buildup at the joint. The cable itself features a rugged, abrasion-resistant jacket capable of withstanding the harsh conditions typical of construction sites, including exposure to oil, grease, and rough surfaces. This durability ensures a long service life and reduces the frequency of cable replacements, contributing to lower operational costs.

Operational Efficiency

By extending the reach of the welding power source, this cable assembly allows operators to access remote or difficult-to-reach weld joints without the logistical burden of moving heavy welding machines. This improves workflow efficiency and safety by reducing clutter and equipment movement on the shop floor. The 3/0 gauge strikes a balance between high current capacity and manageable flexibility, allowing for easier routing around obstacles compared to stiffer, larger-gauge alternatives.
