The Miller Weldcraft W-400 TIG Torch Package (formerly the WP-18SC) is a premium water-cooled solution designed for high-amperage industrial welding environments. Engineered to withstand the rigors of continuous heavy fabrication, this torch is rated for 400 Amps DC and 280 Amps AC, making it ideal for welding thick gauge aluminum, stainless steel, and other demanding alloys. The W-400 distinguishes itself from standard 18-series torches through its enhanced cooling capacity and robust construction, utilizing durable copper components that maximize current transfer while minimizing heat buildup.
This package includes a 25-foot cable assembly featuring high-quality braided rubber hoses. The 3-piece cable design separates power, water, and gas lines, offering superior flexibility and durability compared to vinyl alternatives. The braided rubber resists abrasion and kinking, ensuring consistent coolant and gas flow even in harsh shop conditions. The torch body features a rigid head design, providing a stable platform for precision manipulation of the tungsten electrode. It is optimized for use with heavy-duty stubby collet bodies, which not only improve gas lens performance for superior shielding coverage but also help dissipate heat more effectively at the front end of the torch.
Designed for professional fabricators, the W-400 integrates seamlessly into high-output water-cooled systems. The inclusion of a textured handle improves operator control and reduces grip fatigue during long weld cycles. By maintaining lower operating temperatures, the W-400 extends the lifespan of consumables and reduces the frequency of downtime associated with overheating, delivering a cost-effective solution for high-volume production.
