PowerWeld ZIR532-EA 5/32″ x 7″ 1% Zirconiated Brown Tungsten Electrode (EWZr-1)

The PowerWeld ZIR532 5/32″ x 7″ 1% zirconiated brown tungsten electrode is built for high-amperage AC TIG welding on heavy aluminum and magnesium sections. With a 5/32″ diameter, this tungsten is aimed at thick plate, large castings, and structural welds where strong current capacity and a steady arc are required. Classified as EWZr-1, it uses a zirconium oxide blend that helps minimize tungsten contamination in the weld metal and allows the electrode tip to form and keep a stable balled end on AC. This gives welders a smooth, predictable arc with good puddle control, even when welding at higher amperage levels.

Designed for AC operation, the ZIR532 works well with both traditional transformer TIG machines and modern AC inverter units set up for aluminum TIG welding. The 7″ (175 mm) length fits standard TIG torches and most tungsten grinders. Brown color coding at the tip makes it easy to identify as zirconiated tungsten in mixed racks and storage tubes. For aluminum fabricators, marine and trailer builders, and industrial maintenance crews dealing with heavy non-ferrous components, this 5/32″ EWZr-1 electrode gives the amperage capacity and arc stability needed for demanding AC TIG work. Sold individually, it can be ordered by the each or in groups of (10) to complete a full PowerWeld pack.

Shops and maintenance crews choose the PowerWeld ZIR532 when the job involves heavy aluminum or magnesium sections that demand strong AC TIG performance. The 5/32″ diameter provides the current-carrying capacity needed for deep penetration and long welds on thick plate, structural extrusions, and large castings. The EWZr-1 chemistry is valued in applications where tungsten inclusions need to be kept to a minimum, such as critical structural parts, load-bearing components, and pressure-related welds.

In real-world fabrication and repair work, welders appreciate an electrode that forms a consistent balled tip and delivers a smooth arc at high amperage. This stability makes it easier to manage heat input, control the puddle, and maintain a uniform bead profile from root to cap. Training programs benefit as well, since students can learn how a high-capacity zirconiated tungsten behaves on heavy aluminum, matching the conditions they may see on the job. For operations that routinely push AC TIG hard on thick non-ferrous materials, the PowerWeld ZIR532 provides a reliable, work-focused option.

Why Customers Choose the PowerWeld 5/32″ x 7″ 1% Zirconiated Brown Tungsten Electrode

Welders choose the PowerWeld ZIR532 when they need a 5/32″ zirconiated tungsten electrode that can carry high amperage on thick aluminum and magnesium without sacrificing weld cleanliness. The EWZr-1 formulation is favored wherever tungsten contamination has to be kept under control, such as structural aluminum, heavy marine components, and industrial frames. On AC TIG, this electrode forms a stable balled tip that keeps the arc smooth and predictable, helping technicians manage penetration and bead shape on demanding joints.

For heavy fabrication bays, marine yards, and plant maintenance crews, standardizing on a high-capacity zirconiated tungsten for big aluminum jobs keeps setup straightforward across multiple machines. Operators can set their AC balance, amperage, and travel speeds knowing the electrode will respond consistently from weld to weld. When strong, clean AC TIG performance on thick non-ferrous material is a daily requirement, the PowerWeld ZIR532 is a dependable choice.
