AOZ4598 Features Thorium-Dioxide-Doped Tungsten Electrodes Containing 1.8pct - 2.2pct THO2. The most common type of electrode used on carbon and stainless steel.The higher thoria content in the EWTh-2 electrode causes the operating characteristic improvements to be more pronounced than in the lower thoria content EWTh-1. To use Thoriated electrodes for alternating current welding, balling of the end can be accomplished by briefly, and carefully, welding with direct current electrode positive prior to welding with alternating current. During alternating current welding, the balled end does not melt and so emission is not as good as from a liquid ball on an EWP electrode. GF RADNOR Longer life than 1pct Thoria while providing easy arc starting, stable arc, higher current capacity and increased resistance to weld pool contamination. Electrodes are 100pct Eddy Current tested Annealed brittled for ease of sizing Finest available tungsten powder (APT) Manufactured under a quality system certified to ISO 9001 requirements Meets AWS/ANSI specifications Ground for maximum smoothness UNSPC CODE: 23171500 Material: Tungsten Generic Dimensions 7'' H x 0.125'' W x 0.125'' D Dimensions Overall Length - Top to Bottom: 7 Inches Overall Width - Side to Side: 0.125 Inches Overall Depth - Front to Back: 0.125 Inches
