Tungsten TIG Thoriated Red WT20, excellent arc stability and reliable ignition for DC welding. Recommended for carbon steel, stainless steel and hard alloys. Pack of 10 pieces in 1/16", 5/64" or 3/32" x 6". Reliable performance for critical welds on high-performance metal components.
Red WT20 Thoriated TIG Tungstens are one of the most reliable and widely used options for DC welding in demanding applications. Made of 98% tungsten and approximately 2% thorium oxide, they offer excellent arc stability and reliable ignition at lower amperages.
Recommended for welding:
Stable during long welds and well suited for motorsport and high-performance fabrication.
Despite newer alternatives, red thoriated tungstens are valued for:
Packs of 10 pieces in the following sizes:
Ideal for fabricating chassis parts, manifolds, reinforcements and high-load welds. When precision and reliability matter, these are the ones to trust.
Use with DCEN (direct current electrode negative) and proper grinding. Due to mild radioactivity, handle with care during sharpening and storage.
At Weldracingparts, we choose products that match the needs of demanding workshops. If you’re serious about welding, this tungsten won’t let you down.
