KP2743-1-38S - Lincoln Magnum PRO 550A MIG Nozzle, 3/8 Bore, 1/8 Stickout

Get Better Visibility with the Magnum PRO 3/8" Nozzle

When you are welding in tight corners or need to see exactly where your wire is hitting the joint, the standard flush or recessed nozzle can sometimes get in the way. The Lincoln Electric KP2743-1-38S Magnum PRO Nozzle is the solution for welders who need that extra bit of visibility and access. With a 1/8-inch stickout, the contact tip extends slightly past the end of the nozzle, allowing you to get the arc closer to the root of the weld without the nozzle body obstructing your view or hitting the sidewalls of a narrow groove. This is particularly useful for short-circuit MIG welding or when working on intricate automotive and structural parts.

Don't let the small 3/8-inch opening fool you—this nozzle is built for serious heat. Rated for up to 550 Amps, it can handle the power of heavy-duty industrial MIG guns without melting or deforming. The narrow 3/8-inch ID is perfect for reaching into restricted spaces where a standard 5/8-inch or 1/2-inch nozzle simply won't fit. Because it is part of the Lincoln Magnum PRO line, it features heavy-duty copper construction that resists spatter buildup, meaning you spend less time cleaning your nozzle and more time laying beads. The thread-on design stays tight even when the gun gets hot, so you don't have to worry about it wobbling or falling off mid-weld.

Whether you are running a Magnum PRO 350, 450, or 550 gun, this nozzle is a direct replacement that upgrades your ability to handle difficult joints. It is an essential consumable to keep in your kit for those jobs where standard nozzles are just too bulky. Combine the durability of Lincoln Electric engineering with the precision of a stickout tip configuration, and you get a consumable that helps you produce cleaner, more accurate welds in hard-to-reach places.
