PowerWeld ZIR332-EA 3/32″ x 7″ 1% Zirconiated Brown Tungsten Electrode (EWZr-1)

The PowerWeld ZIR332 3/32″ x 7″ 1% zirconiated brown tungsten electrode is built for AC TIG welding on aluminum and magnesium where weld cleanliness and consistent arc performance matter. The 3/32″ diameter is a versatile size that covers a wide amperage range, from lighter aluminum plate and tube up to heavier sections and castings. Classified as EWZr-1, this electrode uses a zirconium oxide blend that helps minimize tungsten contamination of the weld pool and allows the tip to form and maintain a stable balled end on AC. Welders get a smooth, predictable arc that supports good puddle control and clean bead appearance on non-ferrous joints.

Designed specifically for AC operation, the ZIR332 works well with transformer-style 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, while the brown color at the tip marks it clearly as zirconiated tungsten in mixed storage. For fabrication shops, repair crews, and training programs that handle a mix of aluminum sheet, extrusion, and plate, this 3/32″ EWZr-1 tungsten offers a practical balance of amperage capacity and control. Sold individually, it can be ordered by the each or in groups of (10) electrodes to build out a full PowerWeld pack.

Shops and maintenance crews choose the PowerWeld ZIR332 when they need one zirconiated electrode size that covers much of their AC aluminum TIG work. The 3/32″ diameter handles a wide range of material thicknesses, from lighter plate and tube to heavier sections, so welders can move between tasks without constantly swapping tungsten sizes. The EWZr-1 chemistry is preferred when tungsten contamination must be held to a minimum, which is important on tanks, structural members, and visible aluminum assemblies.

In day-to-day use, welders appreciate how this electrode forms and maintains a steady balled tip on AC, giving a smooth arc and even heat distribution across the joint. That stability helps reduce rework caused by inconsistent penetration or erratic puddle behavior. Training labs also benefit by giving students a realistic, shop-grade electrode that responds well to adjustments in AC balance and amperage. For operations that regularly weld aluminum and magnesium in varied thicknesses, the PowerWeld ZIR332 provides dependable, clean AC TIG performance.

Why Customers Choose the PowerWeld 3/32″ x 7″ 1% Zirconiated Brown Tungsten Electrode

Welders choose the PowerWeld ZIR332 when they want a 3/32″ zirconiated tungsten that can stay in the torch for most AC aluminum work. The EWZr-1 formulation is favored in applications where tungsten inclusions must be kept to a minimum, such as aluminum tanks, frames, and structural welds. On AC TIG, this electrode forms a stable balled tip that keeps the arc smooth and predictable, helping technicians manage heat input and achieve consistent bead profiles.

For fabrication bays, marine builders, and maintenance teams, being able to rely on a single 3/32″ zirconiated tungsten across a wide thickness range keeps setup simple and speeds up changeovers between jobs. Training programs also gain from using this size, since it gives students a realistic feel for how AC aluminum TIG responds to balance, frequency, and amperage settings. When clean, reliable AC TIG performance on aluminum and magnesium is a priority, the PowerWeld ZIR332 is a practical, everyday choice.
