PowerWeld PUR332-EA 3/32″ x 7″ Pure Green Tungsten Electrode (EWP)

The PowerWeld PUR332 3/32″ x 7″ pure green tungsten electrode is a solid choice for AC TIG welding on aluminum and magnesium in general fabrication, repair, and training environments. With its 3/32″ diameter, this electrode covers a wide amperage range, making it suitable for everything from lighter plate and extrusion work to medium-thickness structural joints. Classified as EWP, it is manufactured from unalloyed tungsten, providing good arc stability when used with alternating current, whether you are running a balanced wave setup or a continuously high-frequency stabilized AC output.

On AC TIG, pure tungsten naturally forms a clean, balled end, which many welders prefer for aluminum and magnesium. That balled tip spreads the arc and helps distribute heat evenly, supporting smooth bead appearance on fillet welds, lap joints, and groove welds. The standard 7″ (175 mm) length fits most TIG torches and tungsten grinders, while the green tip color coding clearly identifies it as pure tungsten in a mixed rack of electrodes. Sold individually, the PUR332 is a practical “go-to” size for shops and maintenance crews that rely on traditional pure tungsten for a wide range of AC aluminum work.

Fabricators, maintenance welders, and instructors choose the PowerWeld PUR332 when they want a pure tungsten electrode that can stay in the torch for much of their AC aluminum work. The 3/32″ diameter offers enough amperage capacity for many shop welds while still giving good control on thinner plate and extrusions. On AC, the EWP classification gives a stable arc and a clean, balled tip that spreads heat predictably, which helps welders maintain consistent puddle size and bead shape. Shops that prefer traditional pure tungsten find this size well-suited for a mix of repair and light structural aluminum jobs.

Training programs also benefit from the PUR332, as it lets students experience how pure tungsten behaves across a realistic amperage range before moving on to alloyed electrodes. For day-to-day AC aluminum and magnesium TIG welding where familiar green-tip behavior and versatility are important, the PowerWeld PUR332 is a dependable option.

Why Customers Choose the PowerWeld 3/32″ x 7″ Pure Green Tungsten Electrode

Welders choose the PowerWeld PUR332 when they want a 3/32″ pure tungsten electrode that handles most of their AC aluminum and magnesium TIG welding. The EWP classification and green tip are familiar standards, and the way pure tungsten forms a controlled balled end produces a smooth arc that works well on fillet welds, lap joints, and groove welds in common thicknesses. For many fabrication and maintenance shops, this size becomes the default choice for AC aluminum work.

The 3/32″ diameter is also ideal for training and cross-shop use. It can be run at lower amperage for thinner material and turned up for heavier sections without changing tungsten sizes, giving welders a consistent feel as they move between jobs. When straightforward, traditional pure tungsten performance on AC is preferred, and one electrode size needs to cover a wide range of aluminum tasks, the PowerWeld PUR332 is a practical, reliable solution.
