The Lincoln Electric Flextec 500X / Flex Feed 84 Heavy Duty One-Pak (K3612-4) is a premier multi-process welding solution engineered for the most demanding industrial environments. Designed to deliver up to 500 amps of welding power, this system utilizes advanced inverter technology to provide superior arc performance across a wide range of processes, including MIG, Stick, TIG, Flux-Cored, and Gouging. The unit is built to withstand harsh conditions, boasting an IP23 rating and Desert Duty certification, ensuring operation in temperatures up to 55 degrees Celsius. Its internal components are protected by trayed and potted PC boards, making it a reliable choice for shipyards, construction sites, and heavy fabrication shops.
A defining feature of the Flextec 500X is its integration of CrossLinc Technology. This innovation allows for full remote control of the power source through the standard weld cable, eliminating the need for additional control cables. This not only reduces job site clutter and tripping hazards but also significantly improves productivity by allowing operators to adjust settings at the feeder without returning to the power source. The included Flex Feed 84 wire feeder complements this system with advanced features such as weld memories and timers, providing precise control over welding parameters for consistent, high-quality results.
This One-Pak system is designed for flexibility. It supports a broad spectrum of welding modes, including basic pulse MIG for carbon steel, stainless steel, aluminum, and metalcore electrodes. The power source is compatible with all 42VAC wire feeders and features Arclink connectivity for synergic pulse modes. Stick welding is optimized for both cellulosic and low hydrogen electrodes, while the touch-start TIG feature ensures clean, contamination-free starts without high frequency. Whether for structural fabrication, cross-country pipelines, or heavy equipment repair, the Flextec 500X delivers the power and precision required for professional results.
The K3612-4 One-Pak is a comprehensive turnkey solution that includes the Flextec 500X power source, the Flex Feed 84 heavy-duty wire feeder, and all necessary cables and connections to get started immediately. The system's streamlined interface simplifies setup, while its robust physical design ensures longevity in the field. With a net weight of 205 lbs (93 kg) and a compact footprint, it offers a balance of portability and stationary power, making it a versatile asset for any industrial fleet.
