 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 CooemanPowermatePortable10 grip, goose-neck, and inline styles, the latter used for mechanized welding. Knowing the wire diameter, select a gun rated slightly GallonAirTank higher than the welding current to be used. Duty-cycle ModelC10 ratings are usually given for C[O.sub.2] shielding--air or C[O.sub.2] cooling arc usually sufficient for CooemanPowermatePortable10 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, mounted on a robot arm or fixed within a mechanized welding setup, GallonAirTank guns guide filler ModelC10 wire and shielding gas CooemanPowermatePortable10 into the weld puddle. Mix recovered flux before reusing to maintain its manufactured properties. Three-parts new flux mixed with one-part recovered flux GallonAirTank works well. Consult the flux manufacturer for proper proportions.Fluxes classify as basic, acid, or neutral. Fluxes that contain oxides and break up easily during welding are basic. ModelC10 These provide oxidizing action and alloy with the weld metal to obtain desired mechanical properties. CooemanPowermatePortable10 Acidic oxides break up slightly, for the same reasons. Welding GallonAirTank voltage ModelC10 must remain within the range specified by the manufacturer of acidic and basic fluxes. CooemanPowermatePortable10 Excessive arc voltage reduces the alloying of flux constituents GallonAirTank with the weld metal. Neutral fluxes do not oxidize alloying elements or add alloying elements to the weld. As amperages increase, flux particle size should decrease. Excessive current for a particle size produces unstable art''s and uneven weldbead edges. Shielded-Metal-Arc Welding (SMAW, STICK)AWS (American Welding Society) A5 ModelC10 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, labeled with their CooemanPowermatePortable10 AWS specification and trade name, quality control GallonAirTank (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 numeric designation ModelC10 the grip end.To select a covered SMAW electrode, consider these factors, in approximate order of importance.
