Lincoln Electric Magnum PRO 350A Thread-On Nozzle, 3/8" ID, 1/8" Recess

Reliable Performance for Magnum PRO 350A Guns

Keep your welding operations running smoothly with the Lincoln Electric KP2742-1-38R Thread-On Nozzle. If you are running a Magnum PRO 350A MIG gun, this is the standard replacement nozzle designed to keep your front-end consumables cool and your welds protected. The 3/8-inch bore is ideal for welders who need a balance between gas coverage and accessibility into tighter joints.

One of the biggest frustrations on the shop floor is a nozzle that gets stuck or covered in spatter. Lincoln Electric addresses this with a high-quality nickel plating that sheds spatter far better than bare copper, keeping your nozzle clean for longer. Additionally, the coarse thread design means you won't be fighting to unscrew the nozzle when it's time to change a contact tip or clean the diffuser. It spins on and off easily, even after heating up during long welds.

The 1/8-inch recess places the contact tip slightly back inside the nozzle. This configuration is excellent for protecting the tip from short-circuit spatter and helps maintain a proper stick-out distance, ensuring your shielding gas envelope is fully established before the arc strikes the base metal. Whether you are in general fabrication or heavy manufacturing, this genuine Lincoln consumable ensures your equipment performs at its best.

Key Benefits

• Easy Maintenance: Coarse threads prevent the nozzle from seizing to the diffuser.
