Flextec 350X multi-process power source with CrossLinc® technology and PowerConnect for varying input voltage from 200V to 600V.

Overview

The Lincoln Flextec 350X PowerConnect with Tweco output connectors represents the pinnacle of welding versatility, combining multi-process capabilities with unparalleled input power flexibility. This innovative system automatically adapts to any available input voltage from 200V to 600V, in either single-phase or three-phase configurations, eliminating the need for manual reconnection when moving between job sites with different power supplies. The PowerConnect technology continuously monitors incoming voltage and self-adjusts for optimal performance, allowing welders to focus on productivity rather than power source configuration.

Building on the proven Flextec platform, the 350X PowerConnect supports a comprehensive range of welding processes including Stick, TIG, pulsed and CV MIG, GMAW-STT, and carbon arc gouging. The system includes built-in pulse programs for carbon steel, stainless steel, metal core, and aluminum applications when paired with compatible Power Feed ArcLink wire feeders. This exceptional process flexibility makes the Flextec 350X PowerConnect suitable for diverse applications across construction, fabrication, and industrial environments.

The Flextec 350X PowerConnect features Lincoln's innovative CrossLinc Technology as standard, enabling remote control over welding parameters without additional control cables when used with compatible accessories. The system's comprehensive connectivity supports virtually all Lincoln wire feeder types, including CrossLinc, 14-pin analog, 5-pin ArcLink digital, and across-the-arc models. Based on the same field-proven platform as previous Flextec machines, this model delivers exceptional reliability even in extreme environments, with lab and field testing confirming its durability for demanding applications.
