K4389-1 - HyperFill Dual Wire Inlet Guide for PF84 and 4R220

Unlock High Deposition with the Lincoln K4389-1

The Lincoln Electric K4389-1 HyperFill Inlet Bushing is a critical component designed to unlock the full potential of your welding operations. Engineered exclusively for the revolutionary HyperFill high-deposition welding process, this inlet bushing serves as the bridge between standard wire feeding and advanced dual-wire performance. By allowing you to utilize the HyperFill process, this component helps fabrication shops achieve higher weld deposition rates, improved productivity, and excellent weld quality, all while using a single power source and feeder setup.

Seamless Compatibility

This genuine Lincoln Electric part is manufactured to precise tolerances to ensure perfect compatibility with specific wire feeders. It is designed for use with the 4R220 Robotic Feeder and the PF84 Semi-Automatic Feeder. When installed, it modifies the wire entry point to accept two separate incoming conduits. This is the first step in the HyperFill process, where two smaller diameter wires are fed simultaneously to create a larger, more efficient arc cone. Using OEM parts like the K4389-1 ensures that your expensive feeding equipment remains protected and operates at peak efficiency without the risk of wire shaving or feeding interruptions.

Optimized for Heavy Fabrication

In heavy fabrication environments, downtime and equipment reliability are major concerns. The K4389-1 is built to withstand the rigors of industrial use. Its primary function is to consolidate two incoming wire strands into a single liner path, a task that requires smooth internal geometry to prevent drag and tangling. By ensuring a smooth transition for the wire, this bushing reduces wear on the liner and drive rolls, contributing to a more stable arc and consistent weld bead profile. Whether you are welding structural steel, heavy machinery, or automotive components, integrating this bushing into your PF84 or 4R220 setup is essential for leveraging the speed of HyperFill.

Why Choose Lincoln Electric OEM Parts?

When dealing with advanced processes like HyperFill, precision is key. The K4389-1 is not just a piece of plastic or metal; it is an engineered solution that aligns perfectly with the drive roll mechanics of Lincoln feeders. Using non-standard or makeshift solutions for dual-wire feeding can lead to bird-nesting, erratic feeding, and poor weld quality. Trust in the K4389-1 to provide the reliability you expect from Lincoln Electric, ensuring your high-deposition welding lines keep moving without unnecessary stoppages.
