KP2743-2-75F - Lincoln Magnum PRO 550A Flush MIG Nozzle 3/4-inch Slip-On

Genuine Lincoln Magnum® PRO 550A Flush Nozzle (3/4" ID)

Maximize the performance of your Lincoln Electric welding equipment with the KP2743-2-75F Magnum® PRO 550A Slip-On MIG Nozzle. Designed to meet the rigorous demands of professional welders, this nozzle is an essential component for the Magnum PRO 550A MIG gun platform. It features a standard flush tip geometry, which places the contact tip level with the nozzle exit. This design is favored by many operators for its versatility, providing excellent visibility of the arc and weld puddle while ensuring the contact tip remains protected within the gas envelope. It is an ideal choice for flat and horizontal welding positions where consistent stickout is required.

The construction of the KP2743-2-75F reflects Lincoln Electric's commitment to quality and longevity. The nozzle is manufactured with a high-quality copper alloy base for thermal conductivity, coated in a durable nickel plating. This plating serves a dual purpose: it reflects radiant heat to keep the front-end consumables cooler, and it provides a slick surface that resists spatter adhesion. For welders operating at currents up to 550 amps, heat management is crucial. The cool-running design of the Magnum PRO consumables helps prevent the nozzle from overheating, which can lead to premature failure or insulation breakdown. The result is a consumable that stands up to the heat of heavy fabrication day in and day out.

Efficiency on the shop floor is often determined by ease of maintenance. The slip-on design of this nozzle eliminates the frustration of threaded connections that can become cross-threaded or fused by spatter. A built-in internal spring or friction ring ensures a secure fit on the gas diffuser (specifically compatible with KP2747-2 diffusers) while allowing for easy removal with a simple twist and pull motion. With a 3/4-inch (19 mm) bore, this nozzle is optimized for high-deposition welding, providing a wide umbrella of shielding gas to protect large weld beads. whether you are welding thick structural plate or heavy-walled pipe, this nozzle delivers the reliability you expect from Lincoln Electric.
