0457866880 - ESAB 4M Water-Cooled Power Cable 250A

Precision Power Delivery and Thermal Management

The ESAB Current/Water Cable (SKU: 0457866880) is a critical component designed for the rigorous demands of industrial TIG welding. Engineered to serve as the primary conduit for both welding current and coolant return, this cable assembly is rated for 250 Amps, making it suitable for medium-to-heavy duty welding applications where thermal management is paramount. The assembly features a 4-meter (approximately 13 feet) length, providing the standard reach required for bench work and fabrication cells without introducing excessive voltage drop or hydraulic resistance.

Technically, this cable utilizes a high-conductivity stranded copper conductor housed within a durable, non-conductive hose. This "cable-in-hose" design allows the coolant (water or glycol mixture) to flow directly over the copper strands, effectively dissipating resistive heat generated during the welding process. This active cooling mechanism allows the cable to maintain a smaller profile and greater flexibility compared to air-cooled alternatives of similar amperage ratings. The outer sheath is constructed from high-grade, heat-resistant rubber or synthetic elastomer, selected for its resistance to abrasion, ozone, and incidental contact with hot surfaces typical in welding environments.

Proper maintenance of the current/water cable is essential for equipment longevity. A compromised cable can lead to coolant leaks, which may damage the welding machine's electronics, or increased electrical resistance, resulting in unstable arcs and overheating. This genuine ESAB replacement part ensures exact dimensional compatibility with ESAB torch bodies and machine connectors, guaranteeing a leak-free seal and optimal electrical connection. It is an indispensable spare for maintenance departments managing fleets of water-cooled TIG equipment.
