K1782-7 - Lincoln Electric PTA-17V Air-Cooled TIG Torch, 150A, 12.5ft, 2-Piece Cable

Professional Grade Air-Cooled TIG Performance

The Lincoln Electric PTA-17V Pro-Torch™ (K1782-7) is a premium air-cooled TIG torch designed to meet the rigorous demands of professional fabrication and maintenance environments. Engineered for versatility, this 150-amp torch features a 60% duty cycle, making it a robust choice for welding mild steel, stainless steel, and other alloys in light-to-medium duty applications. The "V" designation indicates the inclusion of a manual gas control valve located directly on the torch body. This critical feature allows the operator to manually open and close the shielding gas flow, a necessity when welding with power sources that do not possess an internal gas solenoid valve, such as many engine-driven welders or stick machines utilized for scratch-start TIG welding.

The torch assembly includes a 12.5-foot, 2-piece cable configuration. In this setup, the power conductor and the gas hose are separate lines, which is often preferred for specific adapter configurations or when replacing existing 2-piece systems. The torch head is constructed from high-quality materials designed to withstand the heat and stress of welding environments while maintaining electrical efficiency. As part of the Pro-Torch™ line, the PTA-17V is built to Lincoln Electric's exacting standards, ensuring compatibility with a wide range of industry-standard 17-series consumables, including collets, collet bodies, and gas nozzles.

Ergonomics play a significant role in the design of the K1782-7. The handle features a specialized knurled texture that provides a positive, non-slip grip, allowing for precise manipulation of the tungsten electrode even when wearing heavy welding gloves. Additionally, the handle incorporates a molded lip or ridge specifically designed to anchor zippered cable covers. This ensures that protective covers remain securely in place, preventing them from sliding down and exposing the cables to potential damage from hot surfaces or sharp edges. Whether used in a production shop or for field repairs, the PTA-17V delivers consistent arc stability and reliable gas coverage.
