The Weldcraft 40V74 Water Hose is a critical component designed for the maintenance and repair of WP-18 series water-cooled TIG torches. Engineered to meet the rigorous demands of industrial welding environments, this hose serves as the primary conduit for coolant delivery to the torch head, ensuring optimal operating temperatures during high-amperage welding cycles. The hose measures 12.5 feet (approximately 3.8 meters) in length, adhering to standard industry sizing for 3-series TIG assemblies. This length provides sufficient reach for bench work and medium-range fabrication cells while maintaining manageable cable management.
Constructed from high-grade vinyl, the 40V74 offers a balance of durability and flexibility. Vinyl is chosen for its resistance to common workshop fluids, including coolants and mild solvents, as well as its ability to withstand the mechanical stresses of daily use. Unlike heavier rubber alternatives, the vinyl composition reduces the overall weight of the cable assembly, which can contribute to improved ergonomics for the welder. The hose comes pre-fitted with standard connections, ensuring immediate compatibility with Weldcraft, Miller, Lincoln, CK Worldwide, and other major brands utilizing the 18-series platform. This direct-fit capability minimizes downtime during maintenance intervals.
Proper cooling is essential for the longevity of TIG consumables and the torch body itself. A compromised water hose can lead to coolant leaks, reduced flow rates, and catastrophic overheating of the power cable or torch head. The 40V74 is manufactured to strict tolerances to ensure a leak-proof seal and consistent flow dynamics. It is specifically identified for use as the water-in or water-out line (depending on specific torch configuration, though typically distinct from the power cable) in standard 3-piece cable assemblies. MRO professionals can rely on this SKU for consistent quality and fitment when refurbishing water-cooled welding stations.
