K1782-11 - Lincoln PTA-17FV Air-Cooled TIG Torch 25ft Flex Head with Valve

Lincoln Electric PTA-17FV Technical Overview

The Lincoln Electric PTA-17FV (K1782-11) is a premium air-cooled TIG torch designed for professional welding applications requiring moderate amperage and high maneuverability. Part of the Pro-Torch™ series, this model is rated at 150 Amps at a 60% duty cycle, making it suitable for a wide range of general fabrication and maintenance tasks. The torch assembly features a 25-foot (7.6 meter) one-piece power cable, which combines the power conductor and gas passage into a single durable line, reducing bulk and simplifying cable management in the field.

This specific configuration is designated "FV" for Flex-Valve. The flexible head allows the operator to physically bend the neck of the torch to various angles, providing superior access to restricted joints and pipe configurations where a rigid torch would fail. The integrated gas valve provides manual control over shielding gas flow directly at the torch handle. This is particularly critical for TIG setups using power sources that lack an internal gas solenoid, such as many engine-driven welders or stick machines adapted for scratch-start or lift-arc TIG welding.

Constructed from high-grade copper and silicone rubber, the PTA-17FV is built to withstand the thermal stresses of continuous welding. The handle features a knurled texture for a secure, non-slip grip, enhancing precision during delicate work. Additionally, a molded lip at the rear of the handle allows for the secure attachment of cable covers, protecting the power cable from abrasion and hot surfaces. The torch utilizes standard 3-series (17/18/26) consumables, ensuring widespread availability of collets, bodies, and nozzles.
