K4587-040 - Lincoln HyperFill Robotic 0.040 Twin-Wire Welding System

Maximize Your Robot's Output with HyperFill

If you are running a robotic welding cell and need to lay down more metal faster, the Lincoln Electric K4587-040 HyperFill Robotic 040 ONE-PAK is the game-changer you've been waiting for. We all know the bottleneck in welding automation is often the deposition rate—the robot can move fast, but can the welding process keep up? HyperFill answers that question with a resounding yes. By running two 0.040-inch wires at the same time through a single gun, you get the deposition rates of a much larger wire or a tandem system, but without the headache of setting up two separate machines. It’s a single feeder, single gun, and single power source solution that acts like a beast.

The "040" in the K4587-040 stands for the wire diameter, and this setup is the sweet spot for a lot of heavy-duty jobs. The twin-wire arc creates a wide, soft puddle that is incredibly forgiving. If your upstream cutting or bending processes aren't perfect and you're dealing with gaps in your fit-up, HyperFill handles it beautifully. The wider arc bridges those gaps that would normally cause burn-through or lack of fusion with a standard single wire. This means your robot keeps welding instead of stopping for alarms or producing parts that need manual touch-up later. It’s about keeping the arc on and the parts moving out the door.

This ONE-PAK is designed to make your life easier. Instead of hunting down individual part numbers for the special contact tips, the specific drive rolls, the gun liner, and the torch itself, Lincoln bundles it all together. You get the specialized robotic gun designed to handle the heat and the dual-wire feed, along with the drive system upgrades needed to push two wires reliably. Programming is a breeze because you are still just teaching one point—the center of the wire. You don't have to worry about lead and trail angles of two separate torches. It’s the simplicity of standard MIG with the horsepower of heavy industrial welding.

Whether you are welding heavy structural beams, agricultural equipment, or pressure vessels, the K4587-040 allows you to step up your game. You get faster travel speeds, smoother beads, and less spatter to clean up. It’s a practical, shop-floor-ready upgrade that turns a standard robotic cell into a high-performance welding station. Upgrade to HyperFill and watch your cycle times drop.
