KP2773-1-B25 - Lincoln Electric Gooseneck Insulator for Magnum PRO 550 - 25 Pack

Protect Your Magnum PRO 550 with Genuine Insulators

Keep your Magnum® PRO 550 MIG gun running smoothly with the Lincoln Electric KP2773-1-B25 Gooseneck Insulator. In the heat of heavy fabrication, the front end of your MIG gun takes a beating. The gooseneck insulator is your first line of defense, sitting inside the gun assembly to electrically isolate the tube and shield it from the inevitable spatter and radiant heat of 550-amp welding. When this part wears out or gets bridged by spatter, you risk erratic arcs, shorts, and damage to the expensive gooseneck itself.

This 25-pack is designed for the professional welder who knows that downtime is the enemy. Having a stock of fresh insulators means you can swap out a degraded part instantly and get back under the hood. These insulators are built tough to handle the high heat of spray transfer and flux-cored welding often associated with the Magnum PRO 550 setup. They fit precisely, ensuring that your gas flow isn't turbulent and your electrical path remains true.

Don't let a small, worn-out component compromise your weld quality or damage your gun. These insulators are easy to install during routine nozzle and tip changes. Simply remove the nozzle and contact tip, slide the old insulator off, and pop a new one on. It’s a small investment that protects the longevity of your torch and helps maintain the smooth, consistent wire feeding and arc stability Lincoln Electric guns are known for.
