K1782-15 - Lincoln PTA-17F Ultra-Flex Air-Cooled TIG Torch 12.5ft Package

Technical Overview of the Lincoln Electric PTA-17F

The Lincoln Electric PTA-17F (K1782-15) is a premium air-cooled TIG torch designed for professional fabrication and maintenance applications. Rated at 150 Amperes with a 60% duty cycle, this torch balances power capacity with lightweight maneuverability. The defining technical characteristic of this model is the "F" designation, indicating a flexible torch head. This mechanical feature allows the operator to manually adjust the angle of the torch neck, facilitating electrode positioning in restricted access joints such as pipe clusters, roll cages, and complex structural assemblies.

The power cable assembly utilizes Lincoln's Ultra-Flex™ technology. Unlike standard rubber or vinyl cables, the Ultra-Flex cable is constructed with high-strand-count copper and a specialized jacket material that offers exceptional pliability. This design minimizes the bend radius and significantly reduces the drag force exerted on the operator's wrist during manipulation of the torch. The cable length is 12.5 feet (3.8 meters) and is configured as a 1-piece system, integrating power and gas flow into a single line for simplified connection to compatible power sources.

Ergonomically, the torch handle features a knurled surface texture. This diamond-pattern texturing provides a high-friction interface for gloved hands, ensuring positive control even in out-of-position welding scenarios. The handle also incorporates a molded rear lip specifically designed to secure a zippered cable cover (such as the K918-1), preventing the cover from sliding down the cable during use. The PTA-17F is compatible with standard 3-Series consumables (10N series collets and bodies), ensuring broad availability of replacement parts and tungsten options ranging from 0.020" to 5/32".

This torch package is an ideal solution for welding power sources requiring a standard air-cooled connection. It is engineered to meet the rigorous demands of aerospace, motorsports, and petrochemical industries where precision and adaptability are critical. The unit comes complete with the torch body, a long back cap, and the power cable assembly.
