The PowerWeld 2PC18 1/8″ x 7″ 2% thoriated red tungsten electrode is built for higher-amperage DC TIG welding on thicker material. The 1/8″ diameter gives strong current-carrying capacity for welds on heavy plate, structural sections, and demanding fabrication work while still maintaining good arc control. Classified as EWTh-2, this electrode uses a thoria alloy that increases electrode life, raises electron emission, and helps keep a sharp point under heat. Welders can push more amps into the joint with fewer stops to regrind, which supports longer passes and multi-pass welds on structural and pressure-related work.
Designed for DC operation, the 2PC18 performs well on carbon steel, stainless steel, nickel alloys, titanium, and copper. The 7″ (175 mm) length fits common TIG torches and most bench or portable tungsten grinders. A red color band at the tip clearly identifies it as 2% thoriated tungsten in your storage rack or toolbox. Sold individually, this TIG tungsten electrode can be purchased one at a time for replacement, or in sets of (10) to build a full PowerWeld pack for production bays and maintenance crews.

Welders in structural shops, heavy fabrication bays, and industrial maintenance teams rely on the PowerWeld 2PC18 when the work demands more heat and longer welds on thick sections. The 1/8″ DC TIG tungsten size lets crews run higher amperage without losing arc stability, which is important on groove welds, buildup passes, and heavy fillets. The EWTh-2 blend delivers strong, consistent arc starting and a tight, focused arc cone that makes it easier to control penetration on carbon steel, stainless, and copper joints.
Maintenance crews and production welders also appreciate how well this 2% thoriated tungsten holds its point during extended runs. Fewer grinding breaks mean more time on the weld and less disruption in workflow, especially on large parts that are difficult to reposition. For operations that depend on high-amperage DC TIG welding on heavy material, the PowerWeld 2PC18 offers a straightforward, work-ready electrode with the durability and performance needed for daily use.

Why Customers Choose the PowerWeld 1/8″ x 7″ 2% Thoriated Red Tungsten Electrode
Crews choose the PowerWeld 2PC18 when they need a 1/8″ DC TIG welding tungsten that can handle heavy welds without sacrificing arc stability. The EWTh-2 formulation offers a strong, focused arc that gives welders confidence when driving heat into thicker carbon steel, stainless, and copper joints. In many fabrication and repair shops, this allows teams to standardize on a single 2% thoriated tungsten electrode for their high-amp DC TIG work, simplifying inventory and machine setup.
The ability of this thoriated TIG tungsten to maintain a sharp point during long welds is another reason it is popular. Operators can make extended passes and multi-pass joints with fewer stops to dress the electrode, which helps maintain a consistent arc shape and improves overall productivity. For heavy fabrication, structural work, and demanding maintenance tasks, the PowerWeld 2PC18 delivers reliable DC TIG performance in a proven 1/8″ x 7″ size.
