 Power SuppliesWelding power supplies take alternating or direct current from a power line or portable generator and convert it to current usable at the welding arc:, Check National Electrical Manufacturers Association (NEMA) Standards Publication EW1, Electric Arc Welding Power Supplies, and manufacturers'' literature for construction and performance requirements of individual machines.Among types of power supplies, alternating-current (ac) transformers are least costly-most use 230 V single phase input aircpmpressorkit and aircpmpressorkit power. Direct-current (DC) transformer-rectifiers convert AC to DC, using single- or three-phase power to produce constant voltage (cv) or variable aircpmpressorkit voltage (vv). AC-DC transformer-rectifiers aircpmpressorkit can AC and DC weld. Duty-Cycle RatingPower-supply rating depends on the type and thickness of the workpiece and the length aircpmpressorkit of time it takes to deposit the longest weld on the thickest material. Duty cycle is the key factor to consider when selecting a power source. Once the engineer has determined the current and voltage needed to accomplish the weld, he then reviews duty cycle requirements.Duty cycle rating is the percentage of time during a 10-minute period a power aircpmpressorkit supply can operate at rated output amperage without overheating. aircpmpressorkit A 300 A machine at 60-percent-duty cycle can weld for six minutes at 300. A during a 10-minute period. Alter six minutes, the welder must rest the machine for the next four minutes to avoid overheating the unit aircpmpressorkit.
