KP2773-2 - Lincoln Electric Magnum PRO 350A Gooseneck Insulator

Keep Your Magnum PRO Running Smoothly

Every welder knows that the secret to a good day in the shop is equipment that behaves. The Lincoln Electric KP2773-2 Gooseneck Insulator is a small but mighty part of your Magnum PRO 350A MIG gun setup. It might just look like a ring of plastic, but this insulator is the only thing standing between your gun tube and a world of trouble. It sits right on the gooseneck, providing a crucial heat shield and spatter guard for the threads that hold your nozzle and diffuser in place.

When you are pushing 350 amps, things get hot fast. The KP2773-2 is built to take that heat without melting or deforming. Its primary job is to stop spatter from fusing to your gun tube. We've all been there—trying to twist off a nozzle that's welded itself to the gun because spatter got into the threads. It kills production time and ruins your rhythm. A fresh insulator keeps those threads clean, meaning your consumables swap out easily, and you can get back to laying beads faster.

Using genuine Lincoln Electric parts means you don't have to worry about fitment. This insulator is designed specifically for the Magnum PRO 350A, so it snaps or screws into place perfectly every time. It also helps electrically isolate the nozzle, which is a lifesaver if you accidentally bump the cup against the workpiece in a tight spot. No arcing, no drama.

Don't let a five-dollar part ruin a five-hundred-dollar torch. Check your insulator every time you change your tip. If it looks chewed up, cracked, or burnt, toss it and put on a fresh KP2773-2. It’s cheap insurance for your welding gun and helps keep your welds clean and your shop efficient. Grab a few spares for your toolbox so you're never caught without one when it counts.
