TUNGSTEN 1/8X7 GRNPURE PK

TUP1257 TECHNIWELD TUNGSTEN 1/8 X 7 PURE PRODUCT DESCRIPTION 1% and 2% thoriated tungsten electrodes, arc starting is easier and wider current ranges can be used. This is due to the addition of thoria. Thoria will not become molten, and it reduces the tendency of the electrode to stick or freeze to the work. A 2% thoriated tungsten electrode has a longer life due to the added thoria. Thoriated tungsten electrodes have a higher resistance to contamination on AC and DC settings and will not cause contamination if accidentally touched to the work. Pure tungsten electrodes provide Good arc stability. They have clean balled ends for AC welding with reasonably good resistance to contamination. Zirconium tungsten electrodes are used primarily for the welding of nuclear components. They provide minimal tungsten contamination. Tolerance on Actual Size, Inches - 0.003” Adheres to American Welding Society standard A5.12M/A5.12:2032 Promotes Reliable Arc Striking and low burn off rate Premium alloy composition to promote longevity of tungsten electrode PRODUCT SPECIFICATIONS Manufacturer: Techniweld USA Brand: Tig Star Hazmat Y/N: No Size 1/8" x 7" Color Green Weight: 0.65 lbs
