The Lincoln Electric Flextec 500X / Flex Feed 74HT One-Pak (K3612-3) is a premier welding system engineered for the most demanding industrial environments. Designed to serve shipyards, construction sites, and heavy fabrication shops, this package combines the raw power of the Flextec 500X inverter with the precision and durability of the Flex Feed 74HT wire feeder. With a rated output of 500 amps at 60% duty cycle, this machine effortlessly handles thick materials and continuous operation requirements.
A standout feature of this system is the integrated CrossLinc Technology. This innovation allows for full voltage control at the feeder without the need for an additional control cable. By communicating voltage settings over the standard weld cable, operators can adjust parameters remotely at the arc, reducing trips back to the power source. This not only increases arc-on time and productivity but also enhances jobsite safety by eliminating unnecessary cable clutter that can lead to trips and falls.
Built to endure, the Flextec 500X boasts an IP23 rating and is Desert Duty rated, ensuring reliable performance in extreme heat, dust, and humidity. The internal components, including PC boards, are trayed and potted to provide superior protection against environmental contaminants. The accompanying Flex Feed 74HT is a high-torque, 4-roll feeder designed to push large diameter wires through long gun cables, making it ideal for structural steel and heavy equipment repair.
This One-Pak is a true multi-process solution, supporting MIG, Stick, TIG, Flux-Cored, and Carbon Arc Gouging. It features optimized stick welding modes for both cellulosic and low-hydrogen electrodes and offers Touch-Start TIG for clean, high-frequency-free arc initiation. Basic Pulse MIG capabilities are standard, providing improved arc performance on carbon steel, stainless steel, and aluminum. The system's flexibility is further enhanced by its broad input voltage compatibility (380/460/575V 3-Phase), ensuring it can be deployed across various facility power configurations.
