The Weldcraft 57N78 Metal Nozzle is a specialized consumable designed for precision TIG welding applications using WP-9, WP-9V, and WP-9P series torches. As a critical component of the torch’s front end, this nozzle directs the flow of shielding gas over the weld pool, protecting the molten metal from atmospheric contamination. The #10 size indicates an orifice diameter of 5\/8 inch (approximately 16mm), which provides a broad umbrella of gas coverage. This is particularly beneficial when welding reactive metals or when sticking the tungsten out further is necessary for visibility or access.<\/p>\n
Unlike standard alumina ceramic cups, this specific listing specifies a metal construction, offering unique durability characteristics for specific industrial environments. The nozzle threads securely onto the collet body or gas lens of the torch, ensuring a tight seal that prevents gas turbulence and aspiration of air. Proper gas coverage is essential for achieving clean, porosity-free welds, and the 57N78 is engineered to deliver a laminar flow pattern that stabilizes the arc.<\/p>\n
Weldcraft, a brand synonymous with quality in the TIG welding industry (now under Miller Electric), manufactures these nozzles to tight tolerances. This ensures consistent fitment across compatible torch bodies, including the popular 9-series air-cooled torches and potentially 20-series water-cooled torches that share similar front-end threading. Whether you are performing maintenance, repair, or fabrication, using genuine Weldcraft parts helps maintain the performance and longevity of your welding equipment.<\/p>\n
This product is sold as a single unit. It is an essential addition to any TIG welder’s consumable kit, allowing for quick changeovers when different gas coverage profiles are required. The 5\/8″ opening is significantly larger than standard #6 or #7 cups, making it a go-to choice for walking the cup on larger pipe or when welding materials that require extra shielding gas protection.<\/p>\n","protected":false},"excerpt":{"rendered":"Weldcraft 57N78 Metal Nozzle #10 (5\/8″) The Weldcraft 57N78 Metal Nozzle is a specialized consumable designed for precision TIG welding applications using WP-9, WP-9V, and WP-9P series torches.
