KP3582-1 - Lincoln Magnum PRO 550A Heavy Duty Nozzle Body

Built for the Heat, Designed for the Welder

If you are pushing 550 amps, you know that heat is the enemy of your consumables. The Lincoln Electric KP3582-1 Magnum PRO Heavy Duty Nozzle Body is designed specifically to handle that heat without failing. When you are deep in a heavy fabrication job, the last thing you want is a nozzle that melts, seizes, or gets so clogged with spatter that you lose gas coverage. This nozzle body tackles those problems head-on.

First, let's talk about spatter. We all hate chipping spatter off the nozzle. The KP3582-1 is nickel-plated, which makes a huge difference. Spatter doesn't stick to nickel the way it sticks to bare copper or brass. Often, a simple tap or a quick wipe is all you need to clear it, keeping your gas flow smooth and your welds porosity-free. This means less time stopping to clean your gun and more time laying down beads.

Second, the threads. There is nothing worse than trying to change a nozzle body that has fused itself to the diffuser because of thermal expansion. Lincoln designed this body with coarse threads to prevent exactly that. Even after a long shift of high-amperage welding, this body is designed to unscrew easily. You won't need to wrestle with it or grab the biggest pair of channel locks in the shop just to swap a part.

This body is part of the Magnum PRO two-piece system. This is great for your wallet and your tool crib. Instead of throwing away a massive, expensive one-piece nozzle when the tip gets banged up, you are just swapping out the front end. It’s a smarter way to weld, giving you the heavy-duty performance of a 550A setup with the convenience and reliability you expect from Lincoln Electric.
