KP14H-40-B100 - Lincoln Magnum Heavy Duty Contact Tip .040 (100 Pack)

Reliable Performance for High-Volume Welding

The Lincoln Electric KP14H-40-B100 Contact Tip is a premium consumable designed to meet the rigorous demands of industrial MIG welding. Specifically engineered for use with Magnum® 200, 300, and 400 amp welding guns, these heavy-duty contact tips are an essential component for maintaining arc stability and ensuring consistent weld quality. This bulk package contains 100 individual tips, making it an ideal solution for large fabrication shops, manufacturing plants, and heavy equipment repair facilities where downtime must be kept to a minimum.

Heavy-Duty Construction

Unlike standard duty tips, the "Heavy Duty" designation of the KP14H series indicates a robust design capable of withstanding higher heat inputs and prolonged welding cycles. The tip is the final point of contact between the welding gun and the wire, transferring the welding current to the electrode. A high-quality tip like the KP14H-40-B100 ensures efficient current transfer, which is critical for maintaining a smooth, spatter-free arc. The .040 inch (1.0 mm) bore is precision-drilled to tight tolerances, accommodating .040 welding wire with just enough clearance to allow smooth feeding while maintaining constant electrical contact.

Optimized for Magnum Systems

Lincoln Electric has designed these tips to integrate seamlessly with their Magnum PRO and standard Magnum gun lines. Using genuine Lincoln consumables ensures that your equipment operates as intended. Mismatched or generic tips can often lead to issues such as micro-arcing inside the bore, premature wear, and erratic wire feeding (often mistaken for liner issues). By sticking with the KP14H-40-B100, operators can trust that the threading and seating of the tip will be perfect every time, preventing gas leaks or overheating at the diffuser junction.

Cost-Effective Bulk Packaging

Consumables are an ongoing cost in any welding operation. Purchasing the KP14H-40-B100 in a 100-pack offers significant value over buying smaller quantities. It simplifies inventory management and ensures that welders always have a fresh tip on hand. Changing contact tips regularly is a best practice in MIG welding; a worn tip can cause the wire to wander (keyholing), leading to poor bead placement and lack of fusion. With a 100-pack supply, operators are encouraged to replace tips as soon as performance degrades, rather than pushing a worn component to failure.
