 Power SuppliesWelding power supplies take alternating or direct current from a power line or portable ColemanPowermatrPortable5 generator and convert it to current usable at the welding arc:, Check National Electrical GallonAirTank Manufacturers Association (NEMA) Standards Publication EW1, Electric Arc Welding Power Supplies, ModelC5 and manufacturers'' literature for construction and performance ColemanPowermatrPortable5 requirements GallonAirTank of individual machines.Among types of power supplies, alternating-current (ac) transformers ModelC5 are least costly-most use 230 ColemanPowermatrPortable5 V single phase input power. Direct-current (DC) transformer-rectifiers convert AC to DC, using single- or three-phase power to produce constant voltage (cv) or GallonAirTank variable voltage (vv). AC-DC transformer-rectifiers can AC and DC weld. GTAW torches come air-cooled and water-cooled. ModelC5 Their heads align in-line with the body or at 90, 120, or ColemanPowermatrPortable5 135 degrees to it. Nozzles, specified by inside diameters, run 1/4 to 5/8 in. Vendors offer special designs: longer to give improved accessibility to the weld joint, or wider to extend shielding gas coverage.Saw guns come in three-types-side, concentric, and deep-groove flux delivery.In GallonAirTank and ModelC5 oxyfuel welding (ofw), ColemanPowermatrPortable5 heat comes from burning gases, rather GallonAirTank than arcs, Torches hold separate tubes for fuel gas and oxygen, blended in a mixer assembly. A torch assembly comprises a handle (aluminum, stainless ModelC5 steel, or brass); a mixing chamber; and ColemanPowermatrPortable5 a brass welding GallonAirTank tip or cutting head. Light-duty torches weld sheer metal to 3/16, in. thick; medium, to 1/2 in.; heavy, 1/2 in. and up. For flux-cored-arc welding, shops use CV or CC types, ModelC5 and ColemanPowermatrPortable5 300 to 1,500 A, 25 to 50 V, rated 60- GallonAirTank to 100-percent-duty cycle. ModelC5 CV types are more popular because wire-feed speed, set before ColemanPowermatrPortable5 welding, controls welding current. Cc types require a variable-speed or voltage-sensing GallonAirTank wire feeder.Gas-tungsten-arc welding (GTAW) ModelC5 requires a constant-current (AC or DC) ColemanPowermatrPortable5 power supply with a steep volt-amp curve to minimize current change for variation in voltage or arc length. They come GallonAirTank rated to 1,500 A, 10 to 75 V, at 40- to 100-percent-duty cycle. Most GTAW power supplies come equipped with high-frequency circuitry for arc initiation and stabilization, gas valves, and cooling-water ModelC5 valves for high-current welding. ColemanPowermatrPortable5 High-frequency arc GallonAirTank start is useful when the maximum open-circuit voltage allowed by NEMA standards, 80 to 100 V, will not establish and maintain a stable arc ModelC5.
