KP26I-75 - Lincoln KP26I-75 Self-Insulated MIG Nozzle 3/4-inch ID

Maximize Gas Coverage with the Lincoln KP26I-75 Nozzle

When you are laying down heavy beads and running high amps, your shielding gas coverage is the line of defense between a perfect weld and a porosity-filled failure. The Lincoln Electric KP26I-75 Gas Nozzle is built for exactly those situations. With a wide 3/4-inch (19 mm) opening, this nozzle delivers a massive envelope of shielding gas around your arc. This is the go-to nozzle for welders working on structural steel, heavy equipment, or any project where you are pushing your machine's duty cycle and need maximum protection for the weld pool.

One of the standout features of the KP26I-75 is its self-insulated design. If you have ever fumbled with separate insulators that crack or get lost, you will appreciate the simplicity of this one-piece solution. It slips right onto your compatible Lincoln MIG gun, providing the necessary electrical isolation without the extra parts. This means faster change-outs on the bench and less downtime troubleshooting gun issues. The insulation is robust, designed to handle the radiant heat of high-amperage spray transfer or globular transfer modes without breaking down prematurely.

Durability is key in a professional shop, and this OEM Lincoln part delivers. The metal construction is tough enough to withstand the inevitable bumps and scrapes of industrial work, while the smooth surface finish helps resist spatter buildup. While it is always good practice to use nozzle dip or spray, the KP26I-75 cleans up easily, keeping your gas flow smooth and turbulent-free. Whether you are replacing a worn-out tip or upgrading your gun setup for a heavy job, this 3/4-inch nozzle gives you the visibility and gas flow control you need to stack dimes with confidence.
