KP3161-1-62F - Lincoln Magnum PRO 550A Thread-On MIG Nozzle, 5/8" Flush, Bottleneck

Reliable Shielding for Professional Welders

Maximize the uptime of your welding operations with the Lincoln Electric KP3161-1-62F Magnum PRO 550A MIG Nozzle. Designed to withstand the rigors of high-amperage welding, this nozzle is rated for 550 amps and is built to keep your welding gun's front end cool even under heavy duty cycles. The KP3161-1-62F features a flush tip relationship, which places the contact tip level with the nozzle exit. This configuration is widely preferred for short-circuit MIG welding and general fabrication as it allows for easy manipulation of the wire stick-out while protecting the tip from accidental arcing against the workpiece.

The nozzle utilizes a robust thread-on mounting system. This design choice eliminates the wobble often associated with friction-fit nozzles, guaranteeing that your gas coverage remains centered over the weld pool. Proper alignment reduces porosity defects caused by atmospheric contamination and ensures a stable arc. The bottleneck profile of the nozzle is particularly advantageous when welding in corners or complex geometries, as it reduces the overall profile of the gun's front end, granting you better sightlines and maneuverability.

Constructed with a high-quality nickel-plated finish, this nozzle is engineered to repel weld spatter. In high-amperage applications where spatter generation can be significant, this plating prevents the nozzle from becoming clogged, ensuring smooth laminar gas flow. This resistance to buildup means you spend less time scraping out your nozzle and more time welding. Whether you are working on structural steel, heavy equipment repair, or production manufacturing, this genuine Lincoln Electric consumable delivers the consistency and longevity professional welders demand.

Note: This nozzle is compatible only with Magnum PRO 550A Thread-On Diffusers. Ensure your MIG gun is equipped with the correct diffuser to utilize this premium consumable.
