PowerWeld LAN15040-EA .040″ x 7″ 1.5% Lanthanated Gold Tungsten Electrode (EWLa-1.5)

The PowerWeld LAN15040 1.5% lanthanated gold tungsten electrode is a reliable choice for precision TIG welding on both ferrous and non-ferrous metals. At .040″ diameter and 7″ (175 mm) long, this small-diameter tungsten is ideal for low-to-medium amperage work where arc control and clean weld appearance matter. The EWLa-1.5 classification gives you a stable arc, easy starting, and a slower tip wear rate compared with pure tungsten, helping reduce downtime for regrinding.

These 1.5% lanthanated tungsten electrodes work with DC current and AC inverter TIG machines, making them suitable for a wide range of shop and field applications. They perform well on carbon steel, stainless steel, nickel alloys, titanium, and aluminum. Gold color coding at the tip makes the tungsten easy to identify in a crowded torch drawer or welding cart. Sold by the each, the LAN15040 is packaged so you can buy exactly what you need, or order (10) pieces to match a standard PowerWeld pack.

PowerWeld .040″ x 7″ 1.5% Lanthanated Gold Tungsten Electrode At a Glance

• EWLa-1.5 Lanthanated Tungsten: Stable arc with reliable starting for TIG welding on multiple metals.
• .040″ Diameter: Suited for low-amp work, thin materials, and detailed welds.

Markets

• Welding and Fabrication Shops Used for production TIG welding on carbon steel, stainless, and mixed alloys.
• Construction and Renovation Handy for on-site TIG jobs such as railings, brackets, and architectural metals.
• Automotive and Motorsport Repair Useful for thin-gauge stainless, chromoly, and aluminum components.
• Manufacturing and Process Plants Supports maintenance welding on piping, tanks, and machinery parts.
• Aerospace and Specialty Metal Work Suited to precision welds on titanium and high-nickel alloys.
• Municipal and Utility Maintenance Reliable for repair tasks where consistent arc starts and clean welds are important.
• Trade Schools and Training Programs Good all-around tungsten for teaching TIG setup and technique.

For welders in fabrication shops, maintenance departments, and training programs, the PowerWeld LAN15040 offers consistent TIG performance with simple setup. Crews working on stainless handrails or thin aluminum sheet benefit from the smooth arc and reduced tendency to spit or wander at low amperage. Maintenance teams appreciate that the same .040 lanthanated tungsten can be used on carbon steel brackets one day and nickel alloy repairs the next, just by changing polarity and settings on the TIG welder. Because 1.5% lanthanated tungsten holds its point longer than pure tungsten, technicians spend less time at the grinder and more time laying in beads. For anyone running AC inverter TIG machines, this gold EWLa-1.5 electrode provides a practical balance of arc stability, electrode life, and versatility across common shop metals.

Why Customers Choose the PowerWeld .040″ x 7″ 1.5% Lanthanated Gold Tungsten Electrode

TIG welders choose the PowerWeld LAN15040 when they need a .040 lanthanated tungsten that works reliably on both steel and aluminum with the same electrode. The EWLa-1.5 blend gives a stable arc on DC for stainless and nickel alloy work, while still performing well on AC inverter TIG settings for aluminum and thin sheet. In shops where torches move between carbon steel brackets, stainless tube, and titanium parts, this single 1.5% lanthanated tungsten electrode keeps setup simple and consistent.

Technicians also like that the gold lanthanated tungsten holds a point longer than pure tungsten, so they can run more welds between sharpening. For everyday TIG jobs that call for a small-diameter TIG welding tungsten, the PowerWeld LAN15040 provides dependable arc starts, good puddle control, and flexible use across different materials without constantly swapping electrodes.
