KP3682-45 - Lincoln Electric 45-Degree Gooseneck Barrel for Magnum PRO 250LX

Restore Precision to Your Magnum PRO 250LX Spool Gun

When you are welding aluminum or other soft alloys, the condition of your spool gun's barrel can make or break the job. The Lincoln Electric KP3682-45 is the 45-degree replacement barrel specifically built for your Magnum® PRO 250LX or 250LXGT. Whether you have damaged your existing neck during a tough job or simply need a fresh liner path for critical work, this genuine Lincoln part gets your equipment back in top fighting shape. The 45-degree angle is the industry standard for a reason—it offers the perfect balance of reach and comfort, allowing you to maintain a proper work angle on fillets and butt joints without straining your wrist.

One of the standout features of the Magnum PRO 250LX system is the ability to rotate the barrel. This replacement unit preserves that functionality perfectly. By loosening the included retaining nut, you can swivel the neck to access tight corners or overhead joints, then lock it back down for a rigid, stable welding platform. This is particularly useful in boat building, trailer fabrication, or automotive repair where access is often restricted. The barrel comes complete with the nut, so you don't have to worry about salvaging stripped or worn hardware from your old setup.

Wire feeding is critical with spool guns, especially when pushing 4043 or 5356 aluminum wire. A bent or worn barrel can introduce drag, leading to erratic arcs or the dreaded burn-back. The KP3682-45 features a smooth internal bore designed to guide the wire effortlessly to the contact tip. This results in a stable arc and consistent bead appearance, which is vital for aesthetic aluminum welds. The robust construction also resists heat buildup, helping to keep your consumables cooler and lasting longer.

Installation is straightforward and takes only minutes, meaning you spend less time fixing tools and more time laying beads. Simply remove the old barrel, seat the new KP3682-45, and tighten the nut. It accepts all your standard Magnum PRO consumables, so there is no need to buy special tips or nozzles. Keep your 250LX running like the pro tool it is with this high-quality replacement barrel.
