Description
CK T147G Pure Tungsten electrodes deliver reliable arc initiation and stable performance for AC welding applications. These 1/4″ diameterpure tungsten electrodes are specifically designed for aluminum welding with conventional AC power sources and transformer-based welders.
Pure tungsten (green tip)provides excellent arc stability when welding aluminum and magnesium alloys using AC current. The larger 1/4″ diameter makes these electrodes ideal for heavy-duty applications requiring higher amperage capacity and extended welding sessions.

Welding Notes
Pure tungsten requires proper ball formation on the electrode tip when using AC current. The electrode naturally forms a molten ball during welding, which provides stable arc characteristics. Do not sharpen pure tungsten – the rounded ball tip is essential for proper AC welding performance. Best suited for conventional transformer-based AC welders rather than inverter-based systems.
Ideal for production welding shops and heavy fabrication operations requiring consistent performance on thick aluminum components using traditional AC welding equipment.
