Description:

Picture is not an actual representation of this item, for sale are the 1/8" x 7" rods Thorium-Dioxide-Doped Tungsten Electrodes Containing 1. 8% - 2. 2% 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. Model # RAD64001960 Features: Longer life than 1% Thoria while providing easy arc starting, stable arc, higher current capacity an Electrodes are 100% 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 specification.
