KP1941-1 - Lincoln Magnum 400 Gooseneck Assembly 82 Degree

Restore Your Magnum 400 to Peak Performance

If you rely on a Lincoln Magnum® 400 MIG gun for your daily welding tasks, you know that the gooseneck takes the brunt of the abuse. From high radiant heat to the occasional accidental drop, the gun tube is a wear item that eventually needs replacement. The Lincoln Electric KP1941-1 is the genuine replacement Gun Tube Assembly you need to get your torch back in fighting shape. Rated for a full 400 amps, this tube is designed to carry the power you need for thick plate and heavy structural welds without overheating. The 82-degree angle provides a natural, comfortable hand position, reducing wrist fatigue during long shifts and helping you maintain the proper torch angle for consistent bead profile.

Why Stick with Genuine Lincoln Parts?

When you are in the middle of a critical job, the last thing you need is equipment failure. Generic aftermarket goosenecks often suffer from poor thread quality or inferior copper alloys, leading to gas leaks and voltage drops. The KP1941-1 is built with high-grade materials that ensure maximum conductivity and durability. A fresh gun tube means better electrical transfer to your contact tip and a smoother path for your welding wire. This translates to a more stable arc, less spatter, and fewer wire feeding bird-nests. It fits perfectly with your existing Magnum 400 handle and consumables, so you don't have to waste time fighting with mismatched parts.

Easy Installation for Minimized Downtime

Swapping out a damaged gun tube is one of the quickest ways to improve your welding experience. The KP1941-1 installs easily into your Magnum 400 handle. Simply remove the old neck, check your liner length, and thread the new one in. It's designed to stand up to the rigors of the shop floor, featuring tough outer insulation that resists cuts and burns. Whether you are welding mild steel, stainless, or aluminum, starting with a straight, clean, and conductive path for your wire is the first step to a quality weld. Don't let a bent or clogged neck hold you back—upgrade to the KP1941-1 and keep your arc smooth and steady.
