K3403-2 - Lincoln Flextec 350X Standard 4-Pack Inverter Rack System

Industrial Multi-Operator Welding Solution

The Lincoln Electric Flextec 350X Standard Compact 4-Pack Rack (K3403-2) is the ultimate solution for field construction and large-scale fabrication environments requiring multiple arcs. This integrated system houses four Flextec 350X Standard multi-process welders within a heavy-duty, industrial-grade steel frame. Designed to streamline job site logistics, the rack allows for the transportation of four high-performance inverters as a single unit, significantly reducing crane lifts and setup time. The robust square tubing construction, including reinforced roof supports, ensures the frame resists twisting and bending during lifting and positioning, providing superior protection for the equipment inside.

One of the primary advantages of this rack system is its electrical efficiency and simplicity. It powers all four welders through a single primary power drop, eliminating the need for a tangled mess of individual power cords and reducing the number of required electrical connections on the job site. This model is wired for 380/460/575V 3-phase input, making it compatible with common industrial and construction site power grids. The entire assembly is IP23 rated, meaning it is engineered for outdoor use and can withstand harsh weather conditions, protecting your investment from the elements.

The included Flextec 350X Standard welders are workhorses of the industry, delivering up to 350 Amps of welding output at 60% duty cycle. They support a wide range of processes including Stick, DC TIG, MIG, Flux-Cored, and Arc Gouging. The "Standard" model features a streamlined operator interface that is easy to set up and use, reducing training time for operators. With a wide output range of 5 to 425 Amps, these machines can handle everything from thin sheet metal to heavy structural steel. The rack system itself is designed with a small footprint, allowing it to fit through standard 36-inch doorways and into personnel elevators, making it ideal for high-rise construction and shipyards.
