KP3359-1-50F - Lincoln Electric Magnum PRO 350A Extended Reach Flush Nozzle, 1/2 Inch Bore

Technical Overview of the Lincoln Electric KP3359-1-50F

The Lincoln Electric KP3359-1-50F is a specialized gas nozzle component engineered for the Magnum® PRO series of semi-automatic welding guns. This consumable is rated for a welding current of 350 Amperes, making it suitable for a wide range of industrial fabrication tasks where consistent thermal management and durability are required. The nozzle features a 1/2-inch (12.7 mm) inner diameter bore, which provides a focused shielding gas column appropriate for standard wire diameters and transfer modes.

A defining technical characteristic of this SKU is its "Extended Reach" geometry. The nozzle body is elongated by 1.5 inches compared to standard configurations. This dimensional modification serves two primary technical functions: it permits the contact tip to access deep or narrow joint configurations that standard nozzles cannot reach, and it increases the standoff distance between the radiant heat of the arc and the gun handle, thereby reducing thermal loading on the gun's front-end consumables and the operator's hand. The tip relationship is defined as "Flush," meaning the contact tip sits flush with the nozzle exit, offering a balanced trade-off between gas coverage and electrode stickout visibility.

Constructed to Lincoln Electric's OEM specifications, the KP3359-1-50F ensures proper seating and electrical isolation within the Magnum PRO front-end assembly. It is designed to resist spatter adhesion and maintain structural integrity under the cyclic heating and cooling inherent in semi-automatic MIG/MAG welding processes. This nozzle is an essential inventory item for facilities utilizing Magnum PRO 350A setups requiring versatile access capabilities.
