KP2745-332R-B100 - Lincoln Magnum PRO Copper Plus Contact Tip 3/32 550A (100-Pack)

High-Performance Contact Tips for Industrial Welding

The Lincoln Electric KP2745-332R Copper Plus Contact Tip is a premium consumable designed to elevate the performance of Magnum PRO MIG guns. Engineered for high-amperage applications, specifically rated for 550A, this contact tip handles the rigorous demands of heavy fabrication and continuous welding cycles. The "Copper Plus" designation refers to a proprietary copper alloy formulation and design that significantly improves heat dissipation. By managing thermal buildup more effectively than standard copper tips, the KP2745-332R resists softening and deformation, ensuring the bore diameter remains consistent over longer periods. This consistency is critical for maintaining stable electrical contact with the welding wire, resulting in a smoother arc and fewer defects.

For industrial facilities and large-scale manufacturing operations, the 100-pack configuration (KP2745-332R-B100) offers substantial logistical advantages. Reducing the frequency of reordering minimizes administrative overhead, while the extended life of each individual tip reduces the downtime associated with consumable changeovers. In automated or semi-automated environments, where every minute of arc-off time impacts productivity, the longevity provided by the Copper Plus technology translates directly to improved throughput. The 3/32 inch (2.4 mm) bore is precision-machined to accommodate heavy welding wires often used in structural steel, shipbuilding, and heavy equipment manufacturing.

Furthermore, the design features a larger mass compared to standard tips. This increased thermal mass acts as a heat sink, pulling heat away from the wire-tip interface. This is particularly beneficial when welding at the upper limits of the duty cycle, preventing the wire from fusing to the tip (burn-back) and reducing the frequency of spatter adhesion. The tips are equipped with coarse threads that resist seizing, making replacement quick and easy even after prolonged exposure to high heat. By integrating these tips into your welding supply chain, you ensure that your Magnum PRO equipment operates at peak efficiency, delivering high-quality welds with reduced consumable waste.
