K2624-1 - Lincoln Precision TIG 375 Ready-Pak Water-Cooled System

Heavy-Duty Precision for Professional Fabrication

The Lincoln Electric Precision TIG 375 Ready-Pak (K2624-1) is the definitive solution for fabrication shops requiring a versatile, high-output AC/DC TIG welding system. Engineered to handle the widest spectrum of material thicknesses, this machine boasts an impressive amperage range of 2 to 420 amps, allowing operators to weld everything from paper-thin alloys to heavy structural sections with a single power source. At the heart of its performance is Lincoln's patented Micro-Start II Technology, which delivers extremely stable low-amperage starting, welding, and cratering, eliminating the common frustrations associated with arc wandering on thin materials.

Advanced Control and Cooling

This Ready-Pak configuration is designed for high-productivity environments where duty cycle and thermal management are critical. It includes the Under-Cooler Cart (K1828-1), which seamlessly integrates a water cooler into the welding cart design, keeping the included PTW-20 torch cool during extended high-amperage welds. The machine features an Advanced Pulse Control panel as standard, enabling TIG pulsing to minimize material distortion and moderate filler metal deposition—essential for consistent bead appearance on stainless steel and aluminum. Furthermore, the AC Auto Balance feature simplifies aluminum welding by automatically adjusting the cleaning and penetration ratio, though operators retain the ability to manually fine-tune these settings for specific joint requirements.

Complete Industrial Package

The K2624-1 is a true turnkey system. It ships fully assembled with the power source mounted to the cooler cart, reducing setup time significantly. The package includes a heavy-duty Foot Amptrol for precise heat control, a Harris gas regulator and flowmeter, a zippered torch cover for cable protection, and a comprehensive parts kit. The side-mounted torch holder and organized cable connections ensure the workspace remains clutter-free. With a rated output of 375 amps at 40% duty cycle, the Precision TIG 375 stands as the highest duty cycle machine in its class, making it the workhorse of choice for general fabrication, automotive, marine, and maintenance applications.
