WP18SC12RM - Miller Weldcraft W-400 Water-Cooled TIG Torch Kit 12.5ft

Miller Weldcraft W-400 Super Cool TIG Torch Kit (WP18SC12RM)

The Miller Weldcraft W-400 Super Cool TIG Torch Kit, formerly known as the WP-18SC, is a premium water-cooled welding solution designed to withstand the rigors of high-amperage industrial applications. Engineered for professional fabricators who demand reliability and performance, this torch package (SKU: WP18SC12RM) delivers a rated output of 400 Amps DC and 280 Amps AC, making it one of the most capable hand-held torches in the 3 Series consumable class. The W-400 is specifically constructed to minimize overheating during prolonged welding cycles, ensuring consistent conductivity and operator comfort even during the most demanding jobs.

At the core of the W-400's performance is its innovative head design and heavy-duty components. The torch utilizes a specialized heavy-duty stubby collet body that significantly improves gas coverage while enhancing the cooling capacity of the front end. This design not only results in cleaner welds due to better shielding but also extends the lifespan of consumables by dissipating heat more effectively than standard collet bodies. The internal construction features durable copper components that maximize current capacity, reducing electrical resistance and ensuring that the full power of your welding machine reaches the arc.

Operator comfort and control are paramount in the design of the W-400. The torch features a textured handle that provides a secure, non-slip grip, allowing for precise manipulation of the torch angle and travel speed. This kit comes complete with a 12.5-foot, 3-piece braided rubber power cable assembly. Braided rubber cables are superior to standard vinyl cables as they offer greater flexibility, resistance to kinking, and durability against hot surfaces and abrasion in the workshop environment. The flexibility of the cable reduces wrist fatigue, enabling welders to maintain high-quality bead profiles over long shifts.

This complete package includes the W-400 torch body, the textured handle, the 12.5-foot braided power cable, a long back cap, a gas hose, and a water hose. It is designed for use with water-cooling systems to maintain optimal operating temperatures. The torch head is rigid and does not include a gas control valve, making it suitable for power sources with built-in gas solenoids. By upgrading to the W-400 Super Cool, shops can reduce downtime associated with overheated torches and frequent consumable replacements.
