KP3075-1-38S - Lincoln Electric Gas Nozzle, 3/8 in ID, 1/4 in Stickout, Thread-On

Genuine Lincoln Electric Magnum PRO Consumable

Optimize your welding setup with the Lincoln Electric KP3075-1-38S Gas Nozzle, specifically manufactured for the Magnum® PRO 100L and Magnum® PRO 175L MIG welding guns. As a genuine OEM part, this nozzle is built to the exacting standards required by professional welders who demand reliability and consistency in their daily operations. The nozzle features a standard shape with a 3/8-inch orifice, making it an excellent choice for general-purpose fabrication, automotive repair, and light industrial projects where a balance between gas coverage and joint access is required.

The KP3075-1-38S is distinguished by its 1/4-inch stickout design. In this configuration, the contact tip sits recessed 1/4 inch back from the nozzle opening. This design feature is advantageous for several reasons. First, it helps prevent the contact tip from shorting out against the workpiece when welding in tight corners or V-grooves. Second, it provides a natural guide for maintaining proper contact-tip-to-work distance (CTWD), which helps novice and experienced welders alike maintain a steady arc. The 3/8-inch ID is tight enough to conserve gas while providing a laminar flow that effectively shields the molten puddle from oxygen and nitrogen in the atmosphere.

Lincoln Electric has engineered this nozzle to withstand the rigors of the welding environment. The exterior is nickel-plated, a feature that significantly reduces the adherence of molten spatter. In MIG welding, spatter buildup inside the nozzle can disrupt gas flow and cause porosity; the spatter-resistant coating on this nozzle minimizes this risk and simplifies cleaning. Additionally, the nozzle features a thread-on connection style. The threads are cut coarsely to prevent the common issue of seizing. Welding nozzles undergo extreme temperature fluctuations, expanding when hot and contracting when cool. Fine threads often bind under these conditions, requiring pliers or excessive force to remove. The coarse threads on the KP3075-1-38S ensure that nozzle changes are quick and frustration-free, keeping your downtime to a minimum.

Whether you are working on mild steel, stainless steel, or aluminum, having the correct nozzle geometry is essential for weld quality. The KP3075-1-38S offers a reliable solution for operators using the popular Magnum PRO series guns found on many Lincoln Power MIG machines. Invest in genuine Lincoln parts to maintain the integrity of your welding arc and ensure the longevity of your welding gun assembly.
