PowerWeld LAN1518-EA 1/8″ x 7″ 1.5% Lanthanated Gold Tungsten Electrode (EWLa-1.5)

The PowerWeld LAN1518 1/8″ x 7″ 1.5% lanthanated gold tungsten electrode is built for higher-amperage TIG welding on thicker plate, heavy sections, and demanding fabrication work. With a 1/8″ diameter, this tungsten offers strong current-carrying capacity while still giving a controlled arc and stable weld puddle. The EWLa-1.5 classification uses a lanthanum oxide blend that delivers easy arc starting, improved arc stability, and a slower tip erosion rate compared with pure tungsten. Welders can push more heat into the joint while keeping a consistent point and clean weld appearance.

This 1.5% lanthanated tungsten works with DC current and AC inverter TIG machines, either polarity, so it fits into almost any shop setup. It performs well on carbon steel, stainless steel, nickel alloys, titanium, and aluminum, making it a dependable choice for mixed-metal work. Gold color coding at the tip identifies it quickly as lanthanated tungsten in your torch rack or storage tubes. Sold by the each, the LAN1518 lets you replace single electrodes as needed or order (10) pieces to match a full PowerWeld pack for production welding and jobsite use.

Markets

• Heavy Welding and Fabrication Shops Used for high-amp TIG welding on plate, structural components, and fixtures.
• Construction and Structural Steel Suitable for welds on beams, columns, brackets, and architectural steel.
• Manufacturing and Industrial Plants Supports heavier repairs on machinery frames, tanks, and process equipment.
• Automotive, Truck, and Equipment Repair Useful for thicker sections, heavy brackets, and reinforced components.
• Aerospace and Specialty Metal Fabrication Handles high-heat TIG welds on titanium and nickel-based alloys.

• Trade Schools and Advanced Training Programs Helps students learn higher-amperage TIG welding techniques.

Welders working in fabrication bays, structural shops, and industrial maintenance teams rely on the PowerWeld LAN1518 when jobs call for more amperage and longer welds on thick material. The 1/8″ size gives the arc the support it needs for deep penetration on plate and structural shapes, while the 1.5% lanthanated blend keeps the arc steady and predictable. Crews can run high-amp DC welds on carbon steel and stainless, then move to AC inverter settings for aluminum or mixed-metal work without changing tungsten type.

Because EWLa-1.5 tungsten holds up well under heat, operators spend less time stopping to regrind after long passes or multi-pass welds. This consistency helps keep production welding moving and prevents interruptions in maintenance work where access and setup time are critical. For shops that need a higher-capacity TIG welding tungsten electrode with reliable performance across a range of alloys, the PowerWeld LAN1518 is a practical, work-ready choice.

Why Customers Choose the PowerWeld 1/8″ x 7″ 1.5% Lanthanated Gold Tungsten Electrode

Welders choose the PowerWeld LAN1518 when they need a 1/8″ TIG tungsten that can carry higher amperage without giving up arc stability. The EWLa-1.5 formula delivers a strong, steady arc on DC for structural steel and stainless plate, while still working well on AC inverter settings for heavier aluminum parts and castings. This makes it a go-to tungsten electrode for shops that move between fabrication work and repair tasks on a mix of materials.

Crews also value the way 1.5% lanthanated tungsten resists rapid tip erosion, even during long, high-heat welds. Fewer trips to the grinder mean more time on the weld, which is important in production runs and time-sensitive maintenance jobs. For anyone looking for a dependable, high-capacity TIG welding tungsten electrode that holds up under demanding conditions, the PowerWeld LAN1518 is a straightforward, reliable option.
