WP18SC25RM - Miller Weldcraft W-400 Water-Cooled TIG Torch Kit, 400A, 25ft Braided Rubber

Industrial-Grade Water-Cooled TIG Solution

The Miller Weldcraft W-400 Super Cool TIG Torch Kit (SKU: WP18SC25RM) represents the pinnacle of high-amperage welding performance in the water-cooled category. Formerly known as the WP-18SC, this torch is engineered specifically to address the thermal challenges associated with heavy-duty industrial fabrication. It features a robust design capable of delivering 400 Amps DC and 280 Amps AC at 100% duty cycle, making it an essential tool for facilities processing thick gauge materials where consistent heat management is critical.

Technically, the W-400 distinguishes itself through the use of durable copper components which significantly maximize current capacity compared to standard brass assemblies. The kit includes a 25-foot, 3-piece braided rubber power cable that offers superior resistance to abrasion and heat while maintaining flexibility in complex work environments. The torch head utilizes a heavy-duty stubby collet body, which not only enhances the cooling capacity but also improves gas coverage over the weld pool, resulting in cleaner, higher-quality welds. This package is a complete ready-to-weld solution containing the torch body, handle, power cable, long back cap, and necessary hoses.

Procurement specialists should note that the W-400 is designed to reduce long-term consumable costs. By minimizing overheating, the lifespan of collets, collet bodies, and nozzles is extended. The unit is compatible with standard 3 Series consumables, ensuring that inventory management remains streamlined. This torch is ideal for aerospace, heavy manufacturing, and precision fabrication sectors requiring reliable, continuous high-output welding.
