PowerWeld PUR532-EA 5/32″ x 7″ Pure Green Tungsten Electrode (EWP)

The PowerWeld PUR532 5/32″ x 7″ pure green tungsten electrode is made for high-amperage AC TIG welding on heavy aluminum and magnesium sections. With its large 5/32″ diameter, this electrode carries the current needed for thick plate, heavy extrusions, and large castings while keeping the arc stable and predictable. Classified as EWP, it uses unalloyed tungsten that delivers good arc stability on alternating current, whether you are running a balanced wave or a continuously high-frequency stabilized AC output.

On AC TIG, pure tungsten forms a clean, balled end that many welders prefer for aluminum and magnesium. That balled tip spreads the arc and helps distribute heat evenly across wide joints, which is important when welding structural members, thick flanges, or buildup work. The standard 7″ (175 mm) length fits most TIG torches and tungsten grinders, while the green color coding at the tip clearly marks it as pure tungsten in mixed storage. Sold individually, the PUR532 is a dependable option for fabrication shops, marine yards, and maintenance crews that use traditional pure tungsten electrodes for their heaviest AC aluminum welding.

In heavy fabrication shops, marine yards, and industrial plants, the PowerWeld PUR532 gives welders a pure tungsten electrode that can take high current on thick aluminum and magnesium. The 5/32″ diameter supports deep penetration and long weld runs on plate and heavy sections, while the balled tip helps spread the arc over wider joints for a smoother weld profile. Crews that favor traditional EWP tungsten appreciate the predictable arc behavior on AC, especially for structural and repair work where consistency matters.

Training programs and advanced students also benefit from using the PUR532 when learning higher-amp AC aluminum welding. It clearly shows how pure tungsten behaves at elevated amperage levels, including how the balled end develops and how the arc responds on large fillet and groove welds. For operations that rely on pure tungsten for their heaviest aluminum and magnesium jobs, this electrode keeps setup straightforward and performance familiar.

Why Customers Choose the PowerWeld 5/32″ x 7″ Pure Green Tungsten Electrode

Welders choose the PowerWeld PUR532 when they need a 5/32″ pure tungsten electrode dedicated to the heaviest AC aluminum and magnesium TIG jobs. The EWP classification and green tip are long-standing standards in the industry, and the way pure tungsten forms a controlled balled end gives a broad, steady arc that works well on thick joints and multi-pass welds. For structural aluminum frames, large castings, and heavy plate, this electrode supports the amperage required while keeping arc behavior familiar and manageable.

Because the PUR532 is focused on AC non-ferrous work, shops often keep it as their “heavy aluminum” tungsten. Crews can reach for it whenever the material gets thicker and higher current is needed, knowing they are using an electrode suited to that range. Training labs can also demonstrate how pure tungsten performs under heavier loads, preparing students for real-world aluminum fabrication and repair. When straightforward, traditional pure tungsten performance is required on thick aluminum and magnesium, the PowerWeld PUR532 is a practical, dependable choice.
