K4811-1 - Lincoln Flexcut 125 Plasma Cutting System

Industrial Grade Plasma Cutting Power

The Lincoln Electric Flexcut 125 (K4811-1) is a powerhouse plasma cutting system engineered for the most demanding industrial environments. Designed to deliver consistent, high-quality cuts on mild steel, stainless steel, and aluminum, this machine stands out with its impressive 125 Amp output and a robust 100% duty cycle. This means operators can run the machine continuously at maximum power without fear of overheating or thermal shutdown, significantly boosting throughput in high-volume fabrication shops.

One of the primary advantages of the Flexcut 125 is its consumable efficiency. Lincoln Electric has designed the torch and consumable ecosystem to last up to six times longer than comparable systems. This reduction in consumable turnover translates directly to lower operating costs and less downtime for changeovers. Whether used for handheld gouging or integrated into a mechanized CNC table, the Flexcut 125 provides a stable, focused arc that produces clean cuts with minimal dross, reducing the need for secondary grinding or preparation.

The unit supports a wide range of input voltages (380V to 575V, 3-phase), making it adaptable to various industrial power grids. Its rugged chassis is built to withstand the dust, dirt, and impact common in shipyards, structural steel plants, and heavy equipment manufacturing facilities. With a severance capacity of 1-1/2 inches and a mechanized pierce capacity of 1 inch, the Flexcut 125 is the reliable solution for heavy plate processing.

Key Industrial Benefits
