KP15HFC-564 - Lincoln Electric 5/64" Heavy Duty Flux-Core Contact Tip (10-Pack)

Precision Engineering for Heavy-Duty Flux-Cored Applications

The Lincoln Electric KP15HFC-564 Contact Tip is a specialized consumable designed to meet the rigorous demands of high-amperage Flux-Cored Arc Welding (FCAW). Engineered for industrial environments where reliability and arc stability are paramount, this contact tip features a 5/64-inch (approximately 2.0 mm) bore geometry specifically calibrated for cored wires. Unlike solid wires, flux-cored wires require specific tip tolerances to accommodate the tubular structure and thermal expansion during the welding process; the 'FC' designation ensures this tip provides the optimal balance between electrical contact and feedability, reducing the risk of micro-arcing inside the tip or wire jamming.

Rated for 500 Amps, the 'HD' (Heavy Duty) classification indicates a robust wall thickness and high-grade copper alloy construction. This design maximizes thermal conductivity, effectively dissipating the intense heat generated at the contact point during prolonged welding cycles. Superior heat management extends the service life of the tip, reducing downtime associated with frequent consumable changes. For automated or manual heavy fabrication sectors—such as structural steel erection, shipbuilding, and heavy equipment manufacturing—maintaining consistent electrical transfer is critical for weld quality. The KP15HFC-564 ensures that current is transferred efficiently to the wire, promoting a stable arc, consistent penetration, and reduced spatter.

This product is supplied in a pack of 10, ensuring that welding operators and maintenance teams have ready access to replacements. It is compatible with standard Lincoln Electric Magnum series guns and other assemblies requiring the KP15 style geometry. By utilizing genuine Lincoln Electric consumables, operators ensure system compatibility and performance integrity across their welding equipment.
