PowerWeld LAN20532-EA 5/32″ x 7″ 2% Lanthanated Blue Tungsten Electrode (EWLa-2)

The PowerWeld LAN20532 5/32″ x 7″ 2% lanthanated blue tungsten electrode is designed for high-amperage TIG welding on thick material and heavy weldments. The 5/32″ diameter provides strong current-carrying capacity for deep penetration welds on plate, structural components, and buildup work while still keeping the arc controlled and predictable. Classified as EWLa-2, this tungsten uses a 2% lanthanum blend that delivers easy arc starting, improved arc stability, and a significantly reduced tip erosion rate compared with pure tungsten. Welders can run hotter and longer with fewer stops at the grinder and more consistent bead appearance from root to cap.

This 2% lanthanated tungsten is suitable for both DC and AC inverter TIG machines, either polarity, making it a practical choice for shops that handle a mix of ferrous and non-ferrous metals. It performs well on carbon steel, stainless steel, nickel alloy, titanium, and aluminum, so crews can use a single tungsten type for many high-amp applications. The standard 7″ (175 mm) length fits common TIG torches and bench or hand-held tungsten grinders. Blue color coding at the tip clearly identifies it as 2% lanthanated tungsten in racks and storage tubes. Sold individually, the LAN20532 can be purchased one at a time or in groups of (10) electrodes to build a full PowerWeld pack for busy fabrication bays and maintenance teams.

Markets

Heavy Welding and Fabrication Shops Used for high-amp TIG welding on plate, large weldments, and structural components.

Construction and Structural Steel Suitable for brackets, stiffeners, and reinforcement work that requires TIG quality.
Manufacturing and Industrial Maintenance Handles heavy repairs on tanks, frames, machinery bases, and fixtures.
Automotive, Truck, and Equipment Fabrication Applied to thicker brackets, crossmembers, and aluminum or steel components.
Aerospace and Specialty Metal Work Supports demanding TIG welds on titanium and nickel-based alloys.
Municipal and Facility Maintenance Practical for plant and infrastructure repairs involving heavier materials.
Trade Schools and Advanced Welding Programs Good electrode for teaching high-amperage TIG on plate and structural material.

In heavy fabrication shops and industrial plants, the PowerWeld LAN20532 gives welders the amperage capacity and stability they need for deep, multi-pass welds on thick sections. The 5/32″ diameter supports strong current without losing arc control, making it useful for groove welds, buildup passes, and critical joints on carbon steel and stainless. Because this EWLa-2 tungsten runs on both DC and AC inverters, crews can also tackle demanding aluminum and mixed-alloy work without changing electrode type, which simplifies setups across stations.

Maintenance teams and advanced students benefit from the longer point life that 2% lanthanated tungsten provides. Even at higher heat levels, the sharpened tip resists rapid erosion, so welders spend more time welding and less time at the grinder. That consistency helps keep bead shape, penetration, and heat input under control on large parts where rework is costly. For operations that push TIG welding hard on thick materials, the LAN20532 is a practical, shop-ready choice.

Why Customers Choose the PowerWeld 5/32″ x 7″ 2% Lanthanated Blue Tungsten Electrode

Welders choose the PowerWeld LAN20532 when they need a 5/32″ tungsten that can handle high-amp TIG work without giving up control or durability. The EWLa-2 formulation provides reliable arc starting and a stable arc cone on both DC and AC inverter settings, so crews can weld heavy carbon steel, stainless, and aluminum sections using one electrode type. This helps standardize setups in larger shops where multiple machines and operators work on similar heavy-duty projects.

The extended point life of 2% lanthanated tungsten is another key advantage. During long welds and multi-pass joints, the tip resists rapid rounding, which keeps the arc shape consistent and reduces the number of grinding breaks. That leads to higher productivity and more uniform weld quality across large components and structural work. For heavy fabrication, equipment building, and advanced TIG training that regularly pushes higher amperage, the PowerWeld LAN20532 offers a reliable, work-focused solution.
