The unique quality of this product is that you do not have to use a shielding gas; MODERATE TO The biggest advantage of having an auto dark welding lens shade is that you dont have to flip up and down the helmet every time you want to adjust the welding material. In contrast, self-shielded, flux-cored electrodes, which require no shielding gas, would have no shielding gas designator in its classification (for example, E71T-8). Auto-darkening helmets perform inside set shade levels, usually #6-#9 and/or #9-13. This arc is struck between the metallic workpiece and the continuously-fed tubular cored consumable filler wire, with both the wire and the metallic workpiece melting together to form a weld joint.
