OVERVIEW

Maximize Your Metal Deposition

Unlock the full potential of your high-deposition welding setup with the Lincoln Electric KP4388-2 HyperFill Drive Roll Kit. If you are running the HyperFill process to lay down metal faster and more efficiently, these drive rolls are the heartbeat of your wire feeding system. Sized perfectly for .045" (1.2mm) wire, they ensure that both strands feed smoothly and evenly, preventing bird-nesting and ensuring a stable arc even at high wire feed speeds.

The HyperFill process changes the game by allowing you to weld with two wires using a single gun and power source. However, this requires precise feeding to work correctly. Standard drive rolls simply can't handle two wires at once without slipping or jamming. The KP4388-2 kit is custom-built for this task, gripping both wires securely to deliver them to the contact tip in perfect unison. This means you get a wider, smoother bead and can finish heavy fabrication jobs in record time.

Installing these rolls is straightforward, fitting directly into compatible Lincoln Power Feed units. Whether you are welding heavy structural steel or manufacturing heavy equipment, having the right drive rolls means less troubleshooting and more arc-on time. Trust the KP4388-2 to keep your HyperFill system running smoothly, shift after shift.

FAQ

The KP4388-2 is specifically designed for .045 inch (1.2 mm) welding wire.

No, this kit is designed specifically for the HyperFill process which feeds two wires simultaneously. Standard single-wire welding requires different drive rolls.

HyperFill is a twin-wire MIG welding solution from Lincoln Electric that uses two smaller diameter wires to create a larger weld pool and increase deposition rates using a single power source and gun.

This kit is compatible with Lincoln Electric wire feeders that support the HyperFill process, such as select Power Feed models.

The kit typically includes the drive rolls. Depending on the specific feeder configuration, separate inlet and outlet guides designed for dual wire may be required.

HyperFill requires feeding two wires at the exact same speed. These rolls have grooves machined to hold two wires side-by-side to ensure positive traction on both strands.

Yes, for example, the KP4388-1 is typically used for smaller wire diameters like .035-.040 inch.
