The Lincoln Electric KP2742-1-62S is a high-performance gas nozzle specifically engineered for the Magnum® PRO 350A series of semi-automatic MIG welding guns. As a critical component of the welding torch's front-end assembly, this nozzle plays a vital role in directing shielding gas over the weld pool, protecting the molten metal from atmospheric contamination. Designed with the professional fabricator in mind, it supports an amperage rating of 350A, making it suitable for a wide range of industrial applications where durability and consistency are paramount.
This nozzle features a 5/8-inch (15.9 mm) inner diameter (bore), which is the standard size for general-purpose welding, offering a balanced gas flow that is effective for wire diameters from .035" up to 5/64". The unit is designed with a 1/8-inch (3.2 mm) stickout. This configuration means the contact tip is recessed slightly within the nozzle, providing a fixed tip-to-work distance that helps protect the contact tip from excessive radiant heat and reduces the likelihood of shorting against the workpiece in tight corners. The thread-on connection mechanism is a significant upgrade over slip-on designs, ensuring that the nozzle remains perfectly concentric with the contact tip for uniform gas coverage and consistent weld quality.
Lincoln Electric has constructed the KP2742-1-62S with a focus on longevity and ease of maintenance. The nozzle is nickel-plated, a surface treatment that offers superior resistance to spatter adhesion compared to bare copper. In high-volume welding environments, spatter buildup can obstruct gas flow and lead to weld porosity; the nickel plating allows for easier removal of spatter, keeping the nozzle clean and functional for longer periods. Additionally, the nozzle utilizes coarse threads to connect to the diffuser. These threads are less prone to cross-threading and are specifically designed to resist seizing, a common issue caused by the thermal expansion and contraction cycles inherent in welding. This ensures that consumable changeovers are quick, tool-free, and frustration-free.
