KP2743-1-62F - Lincoln Magnum PRO 550A Flush Nozzle 5/8 Inch Thread-On

Keep Your MIG Gun Running Cool and Clean

When you are pushing 550 amps, you need consumables that can take the heat. The Lincoln Electric Magnum PRO Nozzle (KP2743-1-62F) is built to deliver premium performance for professional welders who demand reliability. This isn't just a piece of copper; it is a specialized tool designed to keep your welding gun's front end cool and spatter-free, allowing you to focus on laying down the perfect bead rather than constantly cleaning your torch.

One of the biggest headaches in MIG welding is spatter buildup that clogs your nozzle and ruins your gas flow. Lincoln Electric solves this with a durable nickel-plated finish. This specialized coating prevents molten spatter from sticking to the nozzle, making cleanup as simple as a quick wipe or tap. This means you spend less time scraping out your nozzle and more time welding, boosting your overall productivity. Additionally, the nickel plating helps reflect heat, protecting the internal components of your gun from thermal damage.

The KP2743-1-62F features a 5/8-inch bore and a flush tip relationship. A flush nozzle is a versatile choice for many welders, offering a great middle ground between the stick-out of a recessed tip and the tight access of a protruding tip. It allows for good visibility of the puddle while maintaining excellent gas coverage. The thread-on design uses coarse threads, which is a game-changer for anyone who has ever had a nozzle seize up on the diffuser. These threads are designed to resist seizing, ensuring that when it is time to change consumables, the nozzle twists off easily without a fight.

Designed for the Magnum PRO 550A and Curve HDE series guns, this nozzle is the perfect upgrade or replacement for your heavy-duty setup. Whether you are working on structural steel, heavy equipment repair, or general fabrication, trust genuine Lincoln Electric consumables to deliver the consistency and longevity your work requires.
