KP11-35-B100 - Lincoln Electric Magnum Contact Tips .035 (100-Pack)

Optimize Your MIG Welding with Lincoln KP11-35-B100 Consumables

The Lincoln Electric KP11-35-B100 Contact Tip (100-pack) is a critical consumable for operators utilizing Magnum® 100L MIG guns. Engineered to accommodate .035 inch (0.9 mm) wire diameters, these contact tips are manufactured to precise specifications to ensure optimal electrical transfer and mechanical wire guidance. In Gas Metal Arc Welding (GMAW) and Flux-Cored Arc Welding (FCAW), the contact tip is the final point of electrical contact before the arc is struck. Consequently, the quality and condition of the tip directly influence arc stability, bead geometry, and overall weld integrity.

One of the primary challenges in MIG welding is micro-arcing within the contact tip, which occurs when the wire loses contact with the tip wall due to bore wear or improper sizing. This can cause the wire to fuse to the tip (burnback) or result in an unstable, wandering arc. Lincoln Electric addresses this by machining the KP11-35 series tips with high-tolerance concentricity and smooth internal bores. This design minimizes friction while maximizing the surface area available for current transfer, resulting in a "crisp" arc characteristic that professional welders demand.

This 100-piece bulk package is designed for high-throughput environments where minimizing downtime is essential. Frequent tip changes are a reality of heavy-duty welding; having a substantial stock of KP11-35-B100 tips ensures that operators can swap out worn components immediately without halting production to wait for parts. The copper alloy construction is selected for its balance of hardness and electrical conductivity, resisting the abrasive wear of the moving wire while withstanding the intense radiant heat of the welding arc.

Compatibility is key with MIG gun consumables. These tips are specifically threaded and shaped for the front-end assembly of the Magnum 100L, a standard gun found on many Lincoln compact wire feeders and welders. Using OEM parts guarantees that the gas flow dynamics within the nozzle remain undisturbed, preventing porosity caused by turbulent shielding gas coverage. For consistent results and equipment longevity, rely on genuine Lincoln Electric contact tips.
