· PRE-SHARPENED: Our CNC pre-sharpened/grounded tungsten electrodes are here to save your time of complicated preparation work and improve your efficiency.· Durable: Professional machines grind out 22.5 degrees, the grinding point is located in the dead centre, more conducive to welding.· BLUE-2% LANTHANATED: Lanthanated electrodes are popular due to the relative ease of striking an arc and lower amperage required. They perform exceptionally well in both AC and DC applications.· AWS CERTIFIED: AMERICAN Welding Society standard AWS A5.12M/A5.12:2009 conformance. The superior quality ensures a better welding experience.· PROFESSIONAL PACKING: By checking the color of the metal tube, you can quickly and easily distinguish the color and model of tungsten electrodes, saving your time and reducing the possibility of errors.· SPECIFICATION: Diameter: 1/16"; Length: 7"; Quantity: 10pk.
