KP14-564 - Lincoln Magnum 5/64 Contact Tip (10-Pack)

Reliable Performance for Heavy-Duty MIG Welding

The Lincoln Electric KP14-564 Contact Tip is a critical consumable designed specifically for the demands of industrial welding environments. Engineered to fit the widely used Magnum® 300 and Magnum® 400 MIG guns, this contact tip accommodates 5/64-inch (2.0 mm) welding wire, making it an essential component for fabricators working with heavier gauge materials. When precision and arc stability are paramount, using genuine Lincoln Electric consumables ensures that your equipment operates at peak efficiency.

Optimized Electrical Conductivity

The primary function of a contact tip is to transfer welding current to the wire as it passes through the gun. The KP14-564 is manufactured from high-quality copper alloy, providing superior electrical conductivity that promotes a stable arc and consistent weld bead profile. Poor quality or worn tips can lead to micro-arcing inside the bore, causing irregular wire feeding and frustrating burnbacks. By choosing this OEM part, welders can maintain a smooth, spatter-free operation that reduces post-weld cleanup and downtime.

Durability and Fit

Designed for the Magnum series, these tips feature precise threading and bore tolerances. The 5/64-inch bore is strictly calibrated to allow the wire to feed smoothly while maintaining sufficient contact for electrical transfer. This balance minimizes friction while preventing the wire from wandering, which is crucial for accurate joint tracking. The standard tip geometry offers a robust wall thickness that withstands the heat generated during high-amperage welding cycles typical of the Magnum 300 and 400 guns.

Maintenance and Replacement

Contact tips are among the most frequently replaced components in a MIG welding setup. Over time, the bore can become oval-shaped (keyholing) due to the abrasive nature of the wire and electrical erosion. This wear compromises the electrical contact point, leading to an unstable arc. The KP14-564 comes in a convenient pack of 10, allowing shops to keep an ample supply on hand for quick changeovers. Regular inspection and replacement of contact tips are simple maintenance steps that yield significant improvements in weld quality and operator productivity.
