Lincoln Precision TIG 375 AC/DC Welder K2622-1

The Ultimate TIG Experience: Lincoln Precision TIG 375

When your work demands perfection and power, the Lincoln Electric Precision TIG® 375 is the welder of choice. Known as the "Powerhouse" of the Precision TIG family, this machine offers the widest output range in its class (2-420 amps), giving you the flexibility to tackle any job that comes through the door. Whether you are welding delicate automotive parts or heavy structural steel, the Precision TIG 375 delivers consistent, high-quality arcs that professional welders rely on.

Simplicity, Control, and Range

Lincoln Electric has designed this machine around three core principles: Simplicity, Control, and Range. Simplicity is achieved through features like AC Auto Balance®, which automatically sets the perfect mix of cleaning and penetration for aluminum welding, letting you focus on the puddle rather than the settings. Control is placed firmly in your hands with the Advanced Pulse Control panel. By activating the TIG pulser, you can minimize warping on thin sheet metal and achieve that stack-of-dimes look with ease. Range is delivered through the massive 420-amp top end and the incredibly stable low-end start, powered by Micro-Start™ II Technology.

Built for the Professional Shop

Beyond its arc performance, the Precision TIG 375 is built to last. It features a heavy-duty case, a neat side-mounted torch holder to keep your workspace organized, and a storage compartment for consumables. It also excels at Stick welding, capable of running large diameter electrodes for heavy repair work. If you are looking for a machine that sets the standard for performance in the 300+ amp class, the Precision TIG 375 is ready to work as hard as you do.
