 Shielded-Metal-Arc ColemanPowermateoortable10 Welding (SMAW, STICK)AWS (American Welding Society) A5 specifications Set standards for electronics for SMAW of carbon, stainless, and low alloy steels; aluminum copper, and nickel and their alloys and weld-surfacing. Designations for covered electrodes carry the prefix ''E''. Packaged to AWS specifications, electrodes come in boxes, cans, or other containers, GallonAirTank labeled with their AWS specification and trade name, quality control (heat or lot) number, supplier name, ModelC10 diameter and length, and weight of contents. Specifications require that every electrode ColemanPowermateoortable10 bc marked for identification near with its numeric designation the grip end.To select a covered GallonAirTank SMAW electrode, consider these factors, ModelC10 in approximate order of importance. * Reduces the size of the etched zone for improved cosmetics.Less EN time improves cleaning action to remove heavier oxidation, lessens penetration, and widens the bead profile.Inverter-based machines also let operators adjust welding-output frequency from 20 to 250 Hz. Decreasing frequency products a broader arc cone, which widens ColemanPowermateoortable10 the weld-bead profile and better-removes impurities from the surface of the workpiece. It also transfers the maximum amount of energy to the workpiece, ideal for work requiring heavy metal deposition.Increasing frequency produces a tight, focused arc cone. This narrows the weld bead, helpful when welding in corners and on root passes and fillet GallonAirTank welds. Independent amperage control of ModelC10 the EN and EP portions of the AC cycle allows the operator to fine-tune the amount of energy directed into the workpiece, as well as take heat off of the tungsten electrode. A basic, professional-quality ColemanPowermateoortable10 AC GTAW power supply lets the operator adjust for variables: amperage, balance control, and shielding-gas pre-flow and post-flow time. 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 GallonAirTank come in pistol grip, goose-neck, and inline styles, the latter used for mechanized welding. Knowing the wire diameter, select a gun rated slightly higher than the welding current to be used. ModelC10 Duty-cycle ratings are usually given for C[O.sub.2] shielding--air or C[O.sub.2] cooling arc usually sufficient for welding at up ColemanPowermateoortable10 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, mounted on a robot arm or fixed within a mechanized welding setup, guns guide filler GallonAirTank wire and shielding gas into ModelC10 the weld puddle.
