The PowerWeld 2PC040 .040″ x 7″ 2% thoriated red tungsten electrode is built for precise, low-amperage DC TIG welding on thin material and fine detail work. With its small .040″ diameter, this TIG tungsten is well suited for sheet metal, light-gauge tube, and delicate joints where heat control and a narrow arc are critical. The EWTh-2 classification uses a thoria alloy that increases electron emission, supports reliable arc starting, and helps keep a sharp point under load. That means smooth DC arc performance with fewer trips to the grinder, even when you are running repeated short welds or tack sequences.
Designed for DC applications, the 2PC040 performs well on carbon steel, stainless steel, nickel alloys, titanium, and copper when paired with a suitable DC TIG power source. The 7″ (175 mm) length fits most TIG torches and tungsten grinders, while the red tip clearly identifies it as 2% thoriated tungsten in your storage tubes or rack. Sold individually, this .040 TIG tungsten can be purchased one at a time for replacement or in sets of (10) electrodes to build a full PowerWeld pack for light fabrication, precision repair, or training labs focused on thin material work.

For welders working on thin sheet, small brackets, or precision parts, the PowerWeld 2PC040 provides the control needed to keep heat down and welds clean. In fabrication shops and repair settings, this .040 2% thoriated tungsten gives a tight, focused DC arc that makes it easier to avoid burn-through and distortion on stainless and carbon steel panels. Maintenance crews and small-part manufacturers can switch from carbon steel to copper or nickel alloys using the same electrode by adjusting DC TIG settings, which keeps the workflow simple.
Training labs also benefit from this size, as students can learn how DC TIG behaves on thin material with a tungsten diameter matched to the lower amperage range. Because the EWTh-2 blend holds a sharp point, welders spend more time making consistent beads and less time dressing electrodes between passes. For anyone focused on fine, low-amp DC TIG work, the PowerWeld 2PC040 is a practical, shop-ready tungsten choice.

Why Customers Choose the PowerWeld .040″ x 7″ 2% Thoriated Red Tungsten Electrode
Welders choose the PowerWeld 2PC040 when they need a .040″ DC TIG tungsten that gives excellent control on thin materials. The EWTh-2 formulation delivers a focused, predictable arc at low amperage, which helps technicians keep the puddle small and avoid overheating stainless, carbon steel, and copper parts. In many precision and light-fabrication shops, this allows crews to keep a dedicated small-diameter 2% thoriated tungsten on hand for detailed DC TIG work.
The way this TIG welding tungsten electrode holds a sharp point between grindings is another key reason it is popular. Operators can run more tacks and short beads with a consistent arc shape, which improves repeatability on small parts and thin assemblies. For fabrication, repair, and training applications that focus on low-amp DC TIG welding, the PowerWeld 2PC040 offers a dependable, fine-control option in a proven .040″ x 7″ size.
