K4277-1 - Flextec 350X Construction 6-Pack Inverter Rack

Streamlined Power for Large-Scale Operations

The Lincoln Electric Flextec 350X Construction 6-Pack Rack (K4277-1) is the definitive solution for large-scale industrial projects requiring multiple welding arcs. Designed to maximize efficiency and minimize setup time, this rack system consolidates six individual Flextec 350X Construction units into a single, rugged frame. The primary advantage of this configuration is the simplified power distribution; the entire rack requires only one primary power drop, significantly reducing the amount of high-voltage cabling cluttering the job site. This not only improves safety by reducing tripping hazards but also accelerates installation and demobilization times in dynamic environments like shipyards and construction sites.

At the heart of this system is Lincoln's proprietary CrossLinc Technology. This innovation allows for full voltage and amperage control at the wire feeder without the need for an additional control cable. By communicating directly over the welding arc, CrossLinc eliminates a major point of failure—damaged control cords—and allows welders to adjust settings at the point of work, hundreds of feet away from the power source. This results in higher productivity, better weld quality, and reduced movement across the site.

The rack itself is engineered for extreme durability. It features a heavy-duty square tube frame that meets IP23 standards, ensuring protection against outdoor elements. The system is designed with logistics in mind, featuring both forklift pockets and a lifting eye, and is sized to fit through standard 36-inch personnel doorways. For procurement managers and facility planners, the Flextec 350X 6-Pack Rack represents a strategic investment in operational efficiency, offering a high density of welding power with a minimal logistical footprint.
