PWTA917 - PowerWeld PWTA917 TIG Power Cable Adapter for 9 & 17 Series Torches

Technical Overview of the PowerWeld PWTA917

The PowerWeld PWTA917 is a specialized TIG power cable adapter engineered to interface standard air-cooled TIG torches with welding power sources utilizing stud-terminal output connections. Specifically designed for the 9 Series (WP-9) and 17 Series (WP-17) torch families, this component is critical for converting the single-line power/gas cable (1-piece style) into a separate power lug and gas inlet configuration.

Manufactured from high-grade solid brass, the adapter ensures minimal electrical resistance, preventing overheating at the connection point even during prolonged welding operations at its maximum rating of 150 Amps. The unit features a standard 3/8-24 RH female thread to accept the power cable fitting from the torch. On the output side, a robust lug allows for secure bolting to the welder's positive or negative terminal stud. An integrated gas hose extends from the block, allowing for direct connection to a flowmeter or solenoid gas outlet, effectively separating the shielding gas path from the electrical current.

This adapter is an essential component for MRO professionals maintaining or retrofitting TIG welding stations. It ensures compatibility between modern lightweight torches and traditional power sources, maintaining the integrity of the shielding gas envelope while delivering consistent arc stability. Its robust mechanical design withstands the thermal cycles and mechanical stresses common in industrial welding environments.
