K2533-2 - Lincoln Precision TIG 225 Industrial 460/575V AC/DC Welder

Industrial Precision for Professional Fabrication

The Lincoln Electric Precision TIG 225 (K2533-2) is engineered for industrial environments requiring high-voltage input compatibility (460/575V). This machine sets the standard in its class with an impressive 5-230 amp operating range, providing the versatility needed for everything from thin automotive sheet metal to heavier general fabrication tasks. At the core of its performance is Lincoln's patented Micro-Start II Technology, which delivers extremely stable low-amperage starting, welding, and cratering for both AC and DC processes. This ensures that critical welds on delicate materials are executed with flawlessness and consistency.

Designed for the professional welder, the Precision TIG 225 simplifies complex variables. The AC Auto-Balance feature automatically adjusts the cleaning versus penetration levels, optimizing the arc for aluminum welding without requiring constant manual tuning. For applications requiring strict heat management, the built-in TIG Pulser helps minimize material distortion on thin stock and moderates filler metal deposition for a consistent bead appearance. When manual control is preferred, operators can bypass the auto-settings to dial in specific cleaning or penetration ratios to break through heavy oxide layers or achieve deeper fusion.

Beyond TIG capabilities, this machine is a robust Stick welder, capable of handling up to 5/32-inch (4.0 mm) electrodes, including the demanding Fleetweld 5P (E6010). The unit features Fan-As-Needed (F.A.N.) technology, which operates the cooling fan only when necessary, reducing power consumption, noise, and the intake of dust and debris into the machine's internal components. The K2533-2 model comes equipped with a NEMA 6-50R receptacle and a 9-foot input power cord, along with essential cable management accessories like a torch hanger and storage compartment, ensuring an organized and efficient workspace.
