K5000-1 - Lincoln Flex Feed 84 Single Wire Drive Boom Feeder (No UI)

Rugged Reliability for Heavy Fabrication

Take control of your welding workflow with the Lincoln Electric Flex Feed 84 Single Wire Drive Boom Mount Feeder. Designed for the most demanding structural and heavy fabrication jobs, this feeder unit (K5000-1) delivers consistent performance where it matters most. If you are setting up a boom-mounted welding station, this drive unit provides the robust feeding capability you need to keep the arc lit and production moving. Its modular design allows you to place the mechanical drive on the boom while utilizing a separate control box (sold separately) for easy access to settings.

The Flex Feed 84 is built to withstand the rigors of the job site. It features Lincoln's patented MaxTrac® wire drive design, housed in a durable cast aluminum feed plate. With four driven rolls, this system provides superior wire feeding force, ensuring stable arc performance even when using long gun cables or conduits. It is a powerhouse for heavy wire applications, easily handling solid wires up to 3/32 inch and flux-cored wires up to 0.120 inch. Whether you are welding thick structural steel or heavy equipment, this feeder has the torque and grip to deliver.

Lincoln Electric has also prioritized safety and ease of use. The unit includes an electrically isolated stud, making it ready for arc gouging operations when properly configured. A user-selectable wire retract function helps prevent wire stick-out injuries by pulling the wire back into the nozzle at the end of a weld. For maintenance, the tool-less design means you can swap out drive rolls or guides in seconds, minimizing downtime. The encapsulated circuit board adds an extra layer of durability, ensuring that environmental contaminants don't compromise performance.

This model is the "No U/I" version, giving you the flexibility to customize your setup with the specific interface and control box that suits your shop's needs. It comes standard with a gun adapter and inlet bushing, ready to be integrated into your high-performance welding system.
