KP2742-2-62S - Lincoln Electric Magnum PRO 350A Slip-On MIG Nozzle, 5/8 Inch ID, 1/8 Inch Stickout

Performance and Durability for the Professional Welder

When you are running beads all day with a Magnum PRO 350A gun, the last thing you want to worry about is your front-end consumables failing or clogging up. The Lincoln Electric KP2742-2-62S nozzle is built to handle the heat and keep you welding. This isn't just a standard cup; it's designed with the welder's daily reality in mind. The slip-on design is a massive time-saver. We've all fought with threaded nozzles that weld themselves to the diffuser after a hot run. With this slip-on model, you just twist and pull, making it incredibly easy to clean out spatter or swap tips on the fly.

Let's talk about the view. This nozzle features a 1/8-inch stickout. For many welders, this is the sweet spot. It keeps the contact tip protected and recessed enough to prevent it from shorting out on the work, but it's not so deep that you lose sight of your wire placement. Whether you are doing fillet welds or working in a groove, that 1/8-inch stickout gives you the visibility you need to control the puddle accurately. The 5/8-inch bore is the industry standard for a reason—it provides excellent gas coverage for 350-amp work without wasting gas or being too bulky to get into tight corners.

Spatter buildup is the enemy of good gas flow. Lincoln Electric coated this nozzle in high-quality nickel plating to fight back. Spatter doesn't stick to nickel the way it sticks to bare copper. This means you spend less time banging your gun against the table or scraping out the nozzle with pliers, and more time laying down metal. The plating also helps reflect the intense heat of the arc, keeping the nozzle and the front end of your gun cooler. A cooler gun means your consumables last longer, and your hand stays more comfortable during those long trigger-pulls.

This nozzle is a genuine Lincoln Electric part, meaning it fits your Magnum PRO Curve 350A gun perfectly. No rattling, no gas leaks, just a solid, reliable connection. If you are looking to restock your kit or upgrade from a standard copper nozzle, the KP2742-2-62S offers the durability and performance professional fabricators demand.
