WP-18-12-R - Weldcraft W-350 Water-Cooled TIG Torch Kit, 12.5ft Braided Rubber

Heavy-Duty Water-Cooled Performance

The Weldcraft W-350 TIG Torch Package (SKU: WP-18-12-R) represents the pinnacle of high-amperage hand-held welding technology. Formerly known as the WP-18 Series, this torch is engineered specifically for heavy industrial fabrication, aerospace, and manufacturing environments where continuous duty cycles and high heat input are required. The W-350 is a water-cooled system rated at 350 amps DC and 250 amps AC at 100% duty cycle, making it the ideal choice for welding thick aluminum sections, heavy steel plates, and pipe fabrication.

Advanced Cooling Technology

Thermal management is critical in high-amperage TIG welding. The W-350 utilizes a unique cooling design that efficiently circulates coolant through the torch head, significantly reducing operating temperatures. This not only prolongs the life of the consumables and torch body but also ensures operator comfort by keeping the handle cool during extended arc-on times. The reduction in overheating minimizes downtime associated with torch failure or cool-down periods, directly contributing to increased operational efficiency.

Rugged Construction & Braided Leads

This specific package, the WP-18-12-R, distinguishes itself with high-performance braided rubber power cables. Unlike standard vinyl cables, the braided rubber composition offers superior flexibility and resistance to hot surfaces, sparks, and abrasion. This durability is essential in shop environments where cables are frequently dragged across metal floors or around sharp corners. The 12.5-foot (3.8-meter) lead length provides adequate reach for bench work and medium-sized assemblies without compromising coolant flow rates.

Ergonomics and Compatibility

Despite its heavy-duty rating, the W-350 features a streamlined body and a ribbed handle designed to improve grip and reduce forearm fatigue. The rigid head angle ensures a consistent electrode relationship to the workpiece, which is vital for precision manual welding. The torch utilizes standard 3 Series (10N) consumables, ensuring broad compatibility with existing inventory of collets, collet bodies, and alumina nozzles. This package arrives complete with the torch body, handle, power cable, gas hose, water hose, and a long back cap, ready for integration into your water-cooled TIG setup.
