K5004-2 - Lincoln Electric Flex Feed 84 Control Box for Boom Conversion (No UI)

Upgrade Your Shop with the Lincoln Flex Feed 84 Control Box

Take your welding operations to the next level with the Lincoln Electric Flex Feed® 84 Control Box. Designed for professional welders and fabrication shops that need flexibility, this control box allows you to convert your standard Flex Feed 84 bench model into a versatile boom configuration. By mounting the feeder on a boom, you free up valuable floor space and extend your reach, making it easier to weld large structural components or navigate around complex assemblies without moving the entire power source. This unit (K5004-2) comes ready for integration, providing the reliable housing and connection points you need for a seamless upgrade.

Built Tough for Heavy Industry

In the world of heavy manufacturing and structural fabrication, equipment failure is not an option. Lincoln Electric understands this, which is why the Flex Feed 84 Control Box is built with a rugged cast aluminum feed plate and encapsulated electronics. Whether you are dealing with grinding dust, humidity, or the inevitable bumps and knocks of a busy shop, this control box is engineered to withstand it all. It protects your investment and ensures that your wire feeding system continues to operate smoothly, shift after shift. The heavy-duty construction also supports large-diameter wires, giving you the power to tackle thick materials with confidence.

Precision Control at Your Fingertips

Consistency is key to quality welds, and this control box delivers just that. Featuring the advanced MaxTrac® wire drive system, it ensures steady wire feeding even over long conduit runs, preventing the frustration of birdnesting or irregular arcs. The system supports digital presets, allowing you to dial in the exact voltage and wire feed speed required for your procedure. With the ability to save up to four custom settings in memory, you can switch between jobs instantly without re-calibrating. This feature is a game-changer for shops that handle multiple material types or joint configurations daily.

Safety and Ease of Use

Lincoln Electric prioritizes operator safety and convenience. The Flex Feed 84 Control Box includes smart features like a wire retract function, which pulls the wire back into the nozzle after welding to prevent injury from sharp stick-out. Maintenance is also a breeze thanks to the tool-less drive roll system—no more hunting for wrenches when you need to change wire sizes. Whether you are running a single or dual-control setup, this box adapts to your needs, providing a smooth, integrated experience that keeps your production line moving efficiently.
