KP2928-1 - Lincoln Electric KP2928-1 SAW Contact Nozzle 5/32 Inch

Keep Your Arc Stable and Production Moving

When you are running heavy wire, you need a contact tip that can take the heat. The Lincoln Electric KP2928-1 Contact Nozzle is built for the serious welder running 5/32 inch (4.0 mm) wire. If you are tackling thick plate fabrication, structural steel, or pipe welding using Submerged Arc or large diameter flux-cored wires, you know that the contact tip is the unsung hero of the operation. It is the final transfer point for all that welding current, and if it fails, your arc starts stuttering, and your weld quality drops.

This nozzle isn't just a piece of copper; it's a precision tool. The bore is sized perfectly to guide 5/32" wire with just the right amount of clearance. Too tight, and the wire jams; too loose, and you lose electrical contact, leading to micro-arcing inside the tip and a wandering arc on the plate. Lincoln Electric has machined the KP2928-1 to hit that sweet spot, giving you smooth feeding and a crisp, consistent arc start every time you pull the trigger or hit the cycle start button.

Durability matters when you are burning wire all day. The alloy used in the KP2928-1 resists annealing (softening) at high temperatures. This means the tip holds its shape longer, resisting the "keyholing" effect where the hole becomes oval-shaped and ruins your aim. Fewer tip changes mean more arc-on time and less frustration. It is designed to be a direct replacement for your Lincoln heavy-duty guns, screwing in securely and providing a solid electrical connection to the diffuser.

Don't compromise your heavy-duty welds with inferior generic consumables. Using genuine Lincoln Electric parts like the KP2928-1 ensures that your machine performs exactly as the engineers intended. Whether you are in a shipyard, a tank shop, or a heavy equipment repair facility, having a fresh pack of these nozzles on hand ensures you are ready to lay down pounds of metal without fighting your equipment. Swap out that worn tip and feel the difference a fresh contact nozzle makes in your arc stability.
