K1782-16 - Lincoln Electric PTA-9 Ready-To-Weld TIG Torch Package - 125 Amp, Air-Cooled, 12.5 ft

Technical Overview of the Lincoln Electric PTA-9 TIG Torch Package

The Lincoln Electric PTA-9 Ready-To-Weld TIG Torch Package (K1782-16) is a comprehensive solution designed for light-duty TIG welding applications. This assembly features the PTA-9 torch body, a 125-amp air-cooled unit engineered for precision and maneuverability. The torch is rated at 125 amps with a 60% duty cycle, making it suitable for consistent operation in fabrication, maintenance, and repair environments. The cooling method is strictly air-cooled, utilizing the ambient atmosphere to dissipate heat, which eliminates the need for external water coolers and reduces the overall weight of the setup.

The package includes a 12.5-foot (3.8-meter) one-piece power cable constructed from standard rubber. This cable integrates the power conductor and gas passage into a single line, simplifying cable management and reducing drag during welding operations. The connection interface is designed as a direct connector with gas-through plugs, specifically engineered to mate seamlessly with the gun port of compatible Lincoln Electric power sources, such as the POWER MIG® 140 MP® and the Lincoln LE31MP®. This plug-and-play design ensures proper gas flow and electrical conductivity without the need for complex adapters.

Structurally, the torch handle features a knurled texture to enhance operator grip, reducing slippage and fatigue during extended use. A molded lip or ridge is integrated into the handle design, providing a dedicated anchor point for zippered cable covers, which protects the power cable from abrasion and sparks. The head style is rigid, offering a fixed angle for standard welding positions. This SKU is supplied as a complete kit, including a long back cap, an alumina nozzle, two collets, two collet bodies, and two pieces of tungsten, allowing for immediate deployment upon unboxing.
