KP23-37-B25 - Lincoln Electric Gas Nozzle, Fixed Recess, 0.38 Inch ID (25-Pack)

Precision Consumables for High-Volume Fabrication

The Lincoln Electric KP23-37-B25 Gas Nozzle is a critical consumable designed for the rigorous demands of industrial MIG welding. Engineered specifically for the Magnum series of semi-automatic guns—including the Magnum 250LX, Magnum 300, and Magnum 400 series—this nozzle ensures seamless compatibility and optimal performance. The unit features a fixed recess design, which positions the contact tip slightly back within the nozzle bore. This configuration is essential for protecting the contact tip from excessive spatter accumulation and short-circuiting against the workpiece, while also assisting in maintaining the correct electrical stickout (ESO) for stable arc characteristics.

With an inner diameter (ID) of 0.38 inches (9.7 mm), this nozzle provides a focused column of shielding gas, making it suitable for a variety of standard welding joints and wire sizes ranging from .025 inches to 5/64 inches. The 0.38-inch bore strikes a balance between gas coverage and accessibility, allowing the welder to reach into tighter corners than larger bore nozzles would permit, without sacrificing the integrity of the gas shield. The nozzle is constructed from high-quality copper alloy, offering excellent thermal conductivity and resistance to heat deformation during prolonged welding sessions at amperages up to 400A.

This product is supplied as a bulk package of 25 units (indicated by the 'B25' suffix). This packaging configuration is ideal for manufacturing environments, fabrication shops, and heavy equipment repair facilities where consumable turnover is high. By stocking the KP23-37-B25, procurement managers can reduce the frequency of reordering and ensure that welding operators always have immediate access to replacement parts, thereby minimizing downtime and maintaining production efficiency. The nozzle attaches securely to the gun tube, ensuring a leak-free gas seal and consistent performance across the lifespan of the consumable.
