 Shielded-Metal-Arc Welding (SMAW, STICK)AWS (American Welding aircomressorhose Society) A5 specifications Set standards for electronics for SMAW of carbon, stainless, and low alloy steels; aluminum copper, and nickel and their aircomressorhose alloys and weld-surfacing. Designations for covered electrodes carry the prefix ''E''. Packaged to AWS specifications, electrodes come in boxes, cans, aircomressorhose or other containers, labeled with their AWS specification and trade name, quality control (heat or lot) number, supplier name, diameter and length, and weight of contents. Specifications require that every electrode bc marked for identification near with its aircomressorhose numeric designation the grip end.To select a covered SMAW electrode, consider these factors, in approximate order of importance. Welding Torches and GunsUsed for shielded-metal-arc welding, torches (electrode holders). manually controlled, grip ends of electrodes, also called rods-pinch type and collet type are common.GMAW and FCAW guns come in pistol grip, goose-neck, and inline styles, the latter used for mechanized welding. aircomressorhose Knowing the wire diameter, select a gun rated slightly higher than the welding current to be used. Duty-cycle ratings are usually given for C[O.sub.2] shielding--air aircomressorhose or C[O.sub.2] cooling arc usually sufficient for welding at up to 600 A at less than 100 percent duty. Higher amperages require water cooling--high-amperage guns come with tubing for water cooling. Hand-held, aircomressorhose and aircomressorhose mounted on a robot arm or fixed within a mechanized welding aircomressorhose setup, guns guide filler wire and shielding gas into the weld puddle.
