K3410-1 - Flextec 350X 8-Pack Rack Connector Kit

Technical Overview: K3410-1 Rack Expansion

The Lincoln K3410-1 Conversion Kit is a specialized hardware set engineered specifically for the Flextec 350X K3400-1 Inverter Racks. For welding technicians and site foremen, this kit provides the mechanical and electrical bridging components necessary to physically join two independent 4-pack racks into a functional 8-pack assembly. This is not merely a bracket set; it is a structural integration system that maintains the integrity of the lifting eyes and frame rigidity required for heavy industrial use.

Mechanical Integration: The kit utilizes hardened steel bolts to fasten the frames of two K3400-1 racks together. The design ensures that the connection points align perfectly with the existing frame geometry of the Flextec racks. Once bolted, the two units effectively become a single structure. This is critical for safe lifting operations. The unified rack meets the necessary load-bearing requirements to be lifted via the standard lifting eyes, allowing for the transport of the entire assembly—including up to eight Flextec 350X power sources—without the risk of frame flex or separation.

Electrical Configuration: Beyond the mechanical connection, the K3410-1 facilitates a streamlined electrical setup. The conversion allows the power distribution boxes of the two racks to be wired in series. This technical feature is a massive advantage for site power management. Instead of requiring two separate high-voltage disconnects or drops, the modified 8-pack system draws from a single primary input. This ensures that all eight inverters share the main line, simplifying phase balancing and reducing the number of cables running across the shop floor or mud.

Application & Compatibility: This kit is strictly compatible with the Flextec 350X inverter rack systems. It is ideal for applications involving high-volume arc welding, such as structural steel erection and field fabrication. The kit comes with all necessary fasteners and instructions to perform the conversion safely. It allows maintenance teams to reconfigure their fleet based on current project requirements, ensuring that your welding assets are utilized to their maximum potential with minimal downtime for setup.
