K4168-2 - Lincoln Electric PRO-Torch 20H Water-Cooled TIG Torch, 320A, 25ft

Industrial-Grade Precision with the Lincoln Electric PRO-Torch™ 20H

The Lincoln Electric K4168-2 PRO-Torch™ 20H is a premium water-cooled TIG torch designed to meet the rigorous demands of industrial fabrication and production environments. Engineered for high-amperage applications, this torch delivers a robust 320A output at a 100% duty cycle. This exceptional performance capability ensures that professional welders can maintain continuous arcs for extended periods without the risk of the torch overheating, thereby maximizing productivity and reducing downtime associated with equipment cooling.

At the core of the K4168-2 is the 20-series head design, a standard in the industry known for its compact profile relative to its power output. This allows operators to maneuver the torch into tighter spaces that larger, air-cooled torches simply cannot reach. The water-cooling system efficiently dissipates heat, not only protecting the torch body but also extending the lifespan of your consumables (collets, collet bodies, and nozzles). This efficiency translates to lower long-term operating costs and more consistent weld quality, as the tungsten electrode remains stable even under high thermal loads.

The torch comes equipped with a 25-foot, 3-piece cable assembly. This configuration separates the power, water, and gas lines, which often results in a lighter and more flexible feel compared to integrated single-cable systems. The extended length provides ample reach for working on large weldments or moving around fixtures without constantly repositioning the welding power source. Constructed with high-quality materials, the cables are resistant to abrasion and heat, ensuring durability in harsh shop environments.

Lincoln Electric has prioritized operator control with the inclusion of a molded, knurled handle. This texture provides a secure, non-slip grip, which is crucial for the fine motor movements required in precision TIG welding. Whether you are welding aluminum, stainless steel, or exotic alloys, the PRO-Torch™ 20H offers the reliability and performance characteristics necessary to achieve X-ray quality welds consistently.
