KP4482-040 - Lincoln Electric .040 Hyperfill Contact Tip (10-Pack)

Precision Engineering for Twin-Wire Performance

The Lincoln Electric KP4482-040 is a premium contact tip developed specifically for the Hyperfill™ solution, a patented twin-wire GMAW process that revolutionizes heavy fabrication. This 10-pack of contact tips is sized for .040 inch (1.0 mm) wire, serving as the critical interface between your power source and the weld pool. Unlike standard MIG tips, the KP4482-040 features internal geometry designed to guide two smaller wires into a single arc, enabling deposition rates comparable to larger diameter wires but with greater control and ease of use.

Constructed from high-grade copper alloy, these tips offer exceptional resistance to heat and wear. The Hyperfill process often operates at higher energy levels to melt two wires simultaneously, placing significant thermal stress on the front-end consumables. Lincoln Electric has engineered the KP4482-040 to withstand these conditions, maintaining its structural integrity and bore dimension longer than standard tips. This longevity translates to fewer tip changes, less troubleshooting, and more arc-on time for your welding operators.

Compatibility is seamless with Magnum® PRO semi-automatic and robotic guns outfitted with Hyperfill diffusers and nozzles. The secure threaded connection ensures optimal electrical contact, minimizing voltage drop and maximizing the efficiency of the welding circuit. For shops looking to bridge the gap between single-wire MIG and submerged arc productivity, the Hyperfill system—anchored by the KP4482-040 tip—provides a versatile and powerful solution.

Technical Excellence

Every aspect of the KP4482-040 is designed for stability. The tip's bore is strictly toleranced to prevent micro-arcing inside the tip, a common cause of premature failure in high-performance applications. By ensuring consistent contact with both wires, the tip promotes a stable, focused arc cone that delivers deep penetration and excellent side-wall fusion. Equip your shop with the best in class consumables for your advanced welding processes.
