KP11-35 - Lincoln Electric KP11-35 Contact Tip 0.035 (0.9mm) - 10 Pack

High-Quality Replacement Contact Tips for MIG Welding

Maximize the efficiency of your MIG welding operations with the Lincoln Electric KP11-35 Contact Tip 10-Pack. These contact tips are designed to accommodate 0.035-inch (0.9mm) wire, one of the most versatile and commonly used wire diameters for welding mild steel in light-to-medium duty applications. The KP11-35 is built to the specifications of the industry-standard Tweco 11-Series, ensuring a perfect fit for a wide range of MIG guns, including the Tweco Mini, Tweco #1, and the widely used Lincoln Magnum 100L. This universality makes these tips an essential inventory item for any workshop that utilizes compact MIG welders.

The primary function of a contact tip is to transfer the welding current to the electrode wire. To do this effectively, the tip must maintain constant sliding contact with the wire. The Lincoln KP11-35 is manufactured with tight tolerances to ensure the bore size is perfectly matched to 0.035" wire, reducing micro-arcing inside the tip which can cause premature failure and wire burn-back. The copper construction is selected for its superior electrical conductivity and ability to withstand the intense heat generated during the welding process. However, because contact tips are subjected to extreme thermal cycling and mechanical wear, they are considered consumable items that require regular replacement.

Symptoms of a bad contact tip include an unstable arc, the wire sticking to the tip (burn-back), or the wire feeding roughly despite correct tension settings. Having a 10-pack of KP11-35 tips ensures that you can address these issues immediately without halting production to run to the store. These tips are suitable for use with both solid MIG wires (requiring shielding gas) and gasless flux-cored wires, provided the wire diameter is 0.035 inches. This versatility is perfect for welders who switch between different processes depending on the job environment.

For users of Lincoln PowerMIG, SP, and Weld-Pak series welders, these tips are the direct factory replacement part. They thread easily into the gas diffuser, ensuring a tight electrical and mechanical connection. Proper maintenance of your MIG gun's front-end consumables is the easiest way to improve weld quality. Don't let a worn tip compromise your work; stock up on Lincoln KP11-35 contact tips and experience the difference that quality components make in your arc stability and bead profile.
