KP2743-2-62F - Lincoln Magnum PRO 550A Flush Nozzle 5/8 Inch KP2743-2-62F

Genuine Lincoln Electric Magnum PRO Consumable

Optimize your welding setup with the Lincoln Electric KP2743-2-62F, a standard slip-on nozzle tailored for the Magnum PRO 550A MIG gun platform. This nozzle is designed to handle the rigors of professional welding, rated for 550 amps to support intensive arc-on time. It features a 5/8-inch inner diameter (ID), which is the industry standard for general-purpose MIG welding, providing a stable column of shielding gas to protect the molten weld pool from atmospheric contamination.

The KP2743-2-62F utilizes a flush contact tip relationship. In this configuration, the contact tip is aligned perfectly with the nozzle exit. This design is highly effective for short-circuit transfer and spray transfer modes where the operator needs to maintain a consistent electrical stick-out without sacrificing gas protection. It reduces the risk of bridging the nozzle to the workpiece while still allowing for excellent maneuverability in tight corners compared to recessed tips.

Key Benefits of the KP2743-2-62F:

• Spatter Resistance: The high-quality nickel plating acts as a barrier against molten spatter, preventing it from fusing to the nozzle walls. This keeps the gas passages clear and reduces the time spent cleaning the gun.
• Cooling Efficiency: Designed to work in unison with Magnum PRO diffusers and tips, this nozzle helps dissipate heat effectively, keeping the front-end consumables cooler and preventing premature failure.
• Ease of Use: The slip-on friction fit mechanism is secure yet easy to remove. There are no threads to cross or damage, making it ideal for fast-paced welding environments.

This nozzle is compatible with a broad range of wire sizes, from .035" up to 1/8", making it a versatile choice for shops that switch between different welding processes or material thicknesses. By using genuine Lincoln Electric consumables, you ensure that your equipment operates at peak efficiency, maintaining the arc stability and weld quality your projects require.
