301251001 - Weldcraft W-280 Water-Cooled TIG Torch Kit, 25ft, 50mm Dinse

Technical Overview of the Weldcraft W-280 TIG Torch Package

The Weldcraft W-280 (formerly WP-280) is a high-performance water-cooled TIG torch engineered for demanding industrial applications requiring consistent high-amperage output. Assigned SKU 301251001, this package is configured with a 25-foot (7.6 meter) cable assembly and a 50mm Dinse-style connector, making it directly compatible with Miller Dynasty® 280, Maxstar® 200, 280, and 350 power sources without the need for additional adapters.

Technically, the W-280 is rated for 280 Amps DC and 195 Amps AC at a 100% duty cycle. This continuous operation capability is achieved through Weldcraft's proprietary Super Cool™ Technology, which maximizes the surface area within the torch head to enhance heat dissipation. The cooling efficiency is further supported by mechanical fittings that provide secure, leak-resistant connections for gas and water lines. The torch body utilizes a two-piece design with resilient high-temperature silicone rubber insulation, preventing the high-frequency voltage leakage often associated with phenolic insulation materials.

The cable assembly features Tri-Flex™ braided rubber hoses, designed to maintain flexibility even in low-temperature environments, thereby reducing operator fatigue and extending cable service life. The ColorSmart™ hose system aids technicians in rapid setup by clearly differentiating between input water, water/power return, and gas lines. This kit utilizes standard 13N Series (2 Series) consumables, ensuring broad availability of replacement parts such as collets, collet bodies, and nozzles. The torch body also incorporates an anti-rotation feature to prevent handle movement, ensuring precise control during critical welds.
