Lincoln Electric Magnum PRO 350A Slip-On Nozzle, 5/8" ID, 1/8" Recess

Keep Your Arc Stable and Your Gun Cool

Welders know that the front-end consumables are the lifeline of any MIG gun. The Lincoln Electric Magnum® PRO 350A Slip-On Nozzle (KP2742-2-62R) is built to keep you welding longer with less downtime. Designed for the popular Magnum PRO 350A guns, this nozzle features a standard 5/8-inch bore that delivers excellent gas coverage for most general fabrication jobs. Whether you are welding mild steel, stainless, or aluminum, consistent gas shielding is the first step to a porosity-free weld, and this nozzle delivers exactly that.

The 1/8-inch recess is a favorite feature for many operators. By sitting slightly past the contact tip, the nozzle acts as a shield, protecting the tip from accidental contact with the base metal and reducing the frequency of burn-backs. This recess also helps in maintaining the correct contact-tip-to-work distance (CTWD), which is crucial for controlling your arc characteristics. If you are tired of wrestling with stuck threaded nozzles, you will appreciate the slip-on design. It stays secure during welding thanks to the internal retention spring but pulls off easily when it's time to clean out spatter or change a tip.

Spatter buildup is the enemy of productivity, and Lincoln Electric fights back with a high-quality nickel plating on these nozzles. This smooth, durable finish prevents spatter from sticking aggressively to the nozzle walls, making it much easier to clean with a pair of welpers or a quick dip in nozzle gel. This means you spend less time banging your gun against the table and more time laying beads. When paired with genuine Lincoln Magnum PRO contact tips and diffusers, this nozzle completes a high-performance front-end system that stands up to the heat of 350-amp welding day in and day out.
