KP14-40 - Lincoln Electric KP14-40 Magnum Contact Tip .040" (10-Pack)

Lincoln Electric KP14-40 Contact Tip .040 in (1.0 mm) – 10 Pack

The Lincoln Electric KP14-40 Contact Tip is a critical consumable designed specifically for the Magnum® series of MIG welding guns, covering the 200 to 400 amperage range. Engineered to precise tolerances, this contact tip accommodates welding wire with a diameter of .040 inches (1.0 mm), ensuring optimal electrical transfer and consistent arc performance. In industrial welding environments, the contact tip serves as the final point of transfer for welding current to the wire, making its quality and fitment essential for maintaining process stability and weld integrity.

Manufactured by Lincoln Electric, a global leader in arc welding solutions, these contact tips are built to withstand the thermal stresses and mechanical wear associated with high-amperage MIG welding. The KP14-40 features a smooth bore finish that minimizes friction, allowing for uninterrupted wire feeding. This is particularly important in automated or semi-automatic applications where wire feed fluctuations can lead to defects such as burnback, erratic arcs, or porosity. By maintaining a tight yet smooth interface with the wire, the tip ensures that the electrical contact point remains consistent, stabilizing the arc length and heat input.

This package contains 10 contact tips, providing a cost-effective solution for maintenance, repair, and operations (MRO) inventories. Frequent inspection and replacement of contact tips are standard preventive maintenance practices in welding shops. As the bore of a contact tip wears into an oval shape ("keyholing"), electrical conductivity drops and the arc becomes unstable. Having a reliable supply of OEM Lincoln Electric tips ensures that downtime is minimized and that welding operators can quickly restore their equipment to peak performance specifications.

The KP14-40 is compatible with a broad range of Lincoln Magnum® guns, including the Magnum® 200, 300, and 400 models. These guns are widely used in heavy fabrication, structural steel, and manufacturing. Using genuine Lincoln Electric consumables guarantees that the threading and dimensions align perfectly with the gas diffuser and gun neck, preventing gas leaks or overheating caused by poor connections. Whether for mild steel, stainless steel, or flux-cored applications requiring .040" wire, these tips deliver the durability and precision professionals demand.
