Welders Choice 84737477 Tig Welding Rod Tungsten

Product Description

The WELDERS CHOICE 84737477 is a thoriated tungsten TIG welding rod designed for gas tungsten arc welding (GTAW) applications. Each rod measures 5/32 inches in diameter and 7 inches in overall length. Thoriated tungsten electrodes are widely used in TIG welding because thorium oxide improves electron emission, supports arc starts, and extends electrode life compared to pure tungsten. This rod is suited for welding carbon steel, stainless steel, and nickel alloys. Licensed welders and skilled fabricators are the primary users. Sold in a package of 10 rods.

This tungsten electrode is applicable in professional TIG welding setups for both shop and field work. It performs well in DC welding processes on ferrous and nonferrous base metals where a stable, concentrated arc is required. Typical install scenarios include pipe welding, structural fabrication, pressure vessel work, and precision sheet metal joining. This rod is a standard selection for HVAC equipment fabrication shops, pipefitters, and certified welding contractors working to AWS or ASME procedure specifications.

Key Features

• Thoriated tungsten construction improves arc starting and electrode longevity
• 5/32 inches diameter suits medium-amperage DC TIG welding applications
• 7 inches overall length provides standard usable length per rod
• Sold in a quantity of 10 rods per package
• UNSPSC Code 23271810 for procurement and catalog classification

Compatibility

Designed as a standard-geometry thoriated tungsten electrode compatible with TIG welding torches that accept 5/32 inches diameter electrodes. Confirm torch collet size before installation.

Installation Notes

Thoriated tungsten electrodes are installed by certified or licensed welders following applicable AWS, ASME, or employer-qualified welding procedures. Always grind the electrode tip to the geometry specified by the applicable weld procedure before use. Handle thoriated tungsten with care and follow your facility's radiation safety and waste disposal guidelines, as thorium oxide is a low-level radioactive material. Power down and de-energize the welding power source before changing or seating the electrode in the torch collet.
