WP-18-12 - Miller Weldcraft W-350 (WP-18) Water-Cooled TIG Torch Package, 12.5ft

Heavy-Duty Water-Cooled TIG Performance

The Miller Weldcraft W-350 TIG Torch Package (formerly known as the WP-18 Series) is a premier solution for high-amperage industrial welding applications. Engineered to withstand the rigors of continuous heavy-duty fabrication, this water-cooled torch system provides a rated output of 350 Amps DC and 250 Amps AC at a 100% duty cycle. This exceptional thermal management capability makes the W-350 indispensable for manufacturing environments where downtime due to torch overheating is not an option. The package includes the rugged W-350 torch body, a durable handle, and a complete 12.5-foot (3.8-meter) cable assembly comprised of vinyl power, water, and gas hoses.

Technically, the W-350 is designed around the industry-standard Series 3 (10N) consumable platform, ensuring broad compatibility with existing inventory of collets, collet bodies, and nozzles. The cooling system efficiently circulates coolant through the torch head, dissipating heat rapidly to protect both the internal components and the operator's hand. The 3-piece cable configuration separates the power conductor from the gas and water lines, a design choice that facilitates easier maintenance and replacement of individual lines if damaged. The vinyl material used for the hoses offers excellent resistance to abrasion and shop fluids, ensuring longevity in harsh MRO and fabrication settings.

This specific SKU (WP-18-12) is configured with a rigid head, providing a stable and consistent angle for mechanized or manual pipe fabrication, aluminum welding, and structural steel work. The inclusion of a long back cap allows for the use of standard 7-inch tungsten electrodes, maximizing material usage and reducing changeover frequency. For industrial procurement specialists seeking a reliable, high-capacity TIG solution that adheres to the legacy quality of the Weldcraft WP-18, the W-350 represents the direct evolution and current standard.
