PowerWeld ZIR116-EA 1/16″ x 7″ 1% Zirconiated Brown Tungsten Electrode (EWZr-1)

The PowerWeld ZIR116 1/16″ x 7″ 1% zirconiated brown tungsten electrode is designed for AC TIG welding on aluminum and magnesium where weld cleanliness and control are important. With a 1/16″ diameter, this TIG tungsten is a practical choice for light to medium-gauge material, offering more amperage capacity than a .040″ electrode while still keeping the arc tight and manageable. Classified as EWZr-1, it uses a zirconium oxide blend that helps minimize tungsten contamination of the weld metal and allows the electrode to maintain a stable balled tip on AC. This combination supports smooth arc performance and clean weld beads on common non-ferrous joints.

Built for AC operation, the ZIR116 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 a rack of different electrode types. For fabricators, repair technicians, and students who regularly weld aluminum or magnesium components, this 1/16″ EWZr-1 tungsten offers dependable performance in the amperage range used for sheet, tube, and moderate plate thicknesses. Sold individually, it can be ordered one at a time or in groups of (10) electrodes to build a full PowerWeld pack.

Aluminum fabricators, maintenance crews, and training programs rely on the PowerWeld ZIR116 because it covers a wide range of typical AC TIG work on non-ferrous materials. The 1/16″ size provides enough amperage capacity for many shop jobs—from thin aluminum panel repairs to moderate plate and extrusion joints—while still allowing welders to keep the puddle controlled. Crews appreciate using a zirconiated tungsten electrode that is engineered to retain a stable balled tip on AC; this helps maintain a smooth, even arc that spreads heat predictably across the joint.

In real-world production and repair environments, that stability means fewer surprises in the weld pool and less time dealing with tungsten-related inclusions or rework. Training labs can demonstrate proper AC TIG setup on aluminum using an electrode that behaves consistently across the most common thickness range. For anyone looking for a dedicated AC TIG tungsten that balances control and capacity on aluminum and magnesium, the PowerWeld ZIR116 is a practical, work-ready option.

Why Customers Choose the PowerWeld 1/16″ x 7″ 1% Zirconiated Brown Tungsten Electrode

Welders choose the PowerWeld ZIR116 when they need a 1/16″ zirconiated tungsten electrode that can handle most day-to-day AC aluminum TIG jobs. The EWZr-1 formulation is preferred in applications where tungsten contamination of the weld must be minimized, such as aluminum tanks, structural components, and visible panels. On AC TIG, this electrode forms and holds a controlled balled tip, giving a smooth, predictable arc that helps maintain uniform bead shape and penetration.

For shops and maintenance teams that often weld aluminum or magnesium in the light to medium thickness range, standardizing on a 1/16″ zirconiated tungsten keeps setup simple and consistent across machines. Operators can tune their AC balance and amperage knowing the electrode will respond in a familiar way. Training programs also benefit, as students learn AC aluminum TIG with a size and type they are likely to encounter in the field. When reliable, clean AC TIG performance on aluminum is the priority, the PowerWeld ZIR116 is a dependable choice.
