The Lincoln Electric KP2745-040R is a premium contact tip designed for the Magnum® PRO series of semi-automatic and robotic MIG guns. Engineered for industrial welding applications requiring 0.040 inch (1.0 mm) wire, this contact tip is rated for 550 amps, providing the thermal durability needed for high-deposition welding. This product is supplied in a convenient pack of 10, ensuring you have the necessary inventory to maintain continuous operations.
At the core of this consumable is Lincoln's Copper Plus® alloy formulation. In high-amperage welding, heat buildup is the primary cause of contact tip failure. Excessive heat softens the copper, leading to rapid wear of the bore (keyholing) and erratic arc characteristics. The KP2745-040R addresses this with a specialized design that increases the mass of the tip relative to the bore size, acting as a superior heat sink. This thermal management capability ensures that the tip retains its structural integrity for longer periods, even under high duty cycles.
Compatibility is key for efficient shop management. These tips are designed to thread securely into Magnum PRO diffusers, providing a low-resistance electrical path that promotes smooth wire feeding and consistent arc starts. The 0.040-inch bore is machined to tight tolerances to ensure positive electrical contact with the welding wire without causing drag or feeding issues. For fabricators utilizing Lincoln Electric power sources and wire feeders, using genuine Magnum PRO expendables like the KP2745-040R is the best way to guarantee system performance and weld quality.
