K3442-1 - Lincoln Flextec 350X Standard Multi-Process Welder

Rugged Industrial Multi-Process Power Source

The Lincoln Electric K3442-1 Flextec 350X Standard is engineered to deliver reliable performance in the most demanding industrial environments. Designed for construction, fabrication, and shipbuilding, this multi-process welder combines simplicity with advanced technology. At its core is Lincoln's CrossLinc™ Technology, which allows for full functionality and control at the arc without the need for extra control cables. This innovation not only reduces cable clutter but also enhances safety and productivity by allowing operators to adjust settings remotely when paired with a CrossLinc-compatible wire feeder.

Built to withstand extreme conditions, the Flextec 350X boasts an IP23 rating, ensuring the internal components are fully encapsulated and protected against environmental hazards like dust and moisture. It is also Desert Duty Rated™, capable of operating efficiently in temperatures as high as 55°C. The machine supports a wide range of processes including Stick, DC TIG, MIG, and Flux-Cored welding, as well as Arc Gouging with carbons up to 3/16 inch (4.8 mm). With a broad amperage range of 5-425 A, it provides the versatility needed for various material thicknesses and welding applications.

The Standard model features a streamlined operator panel that minimizes setup time, making it easy for operators to switch between processes. It connects to any 380-600V 3-phase power source, offering flexibility across different job sites. Safety is paramount with the built-in VRD® (Voltage Reduction Device), which lowers the Open Circuit Voltage when not welding to protect the operator. Whether you are working in a fabrication shop or an outdoor construction site, the Flextec 350X Standard delivers the power and durability required for heavy-duty industrial MRO tasks.
