 Duty-Cycle RatingPower-supply rating depends on the type and thickness of the workpiece and the length 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 auxoliarytankforaircompressor and auxoliarytankforaircompressor is the percentage of time during a 10-minute period a power supply can operate at rated output amperage without overheating. A 300 A machine at 60-percent-duty cycle auxoliarytankforaircompressor 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. Saw Uses CV or CC Power Supplies,... 200 to 1,500 A, 28 to 44 V, at 60- to 100-percent-duty cycle. Automatic units auxoliarytankforaircompressor commonly use up to 1,500 A on one wire. Cv welding machines that offer variable-slope control give the welder extra adjustability, and can extend the usefulness of the machine to weld a range of material thicknesses and types.Selection of Power SourcesWhen choosing a power source, start by checking auxoliarytankforaircompressor NEMA specs. NEMA Class I arc-welding power sources deliver rated output at 60-, 80-, or 100-percent-duty cycle: Class II units, 30-, 40-, or 50-percent; and Class III, 20 auxoliarytankforaircompressor percent. First consider capacity and kind of current needed for the job. Rely on the manufacturer''s rating as being conservative: auxoliarytankforaircompressor don''t buy more capacity than auxoliarytankforaircompressor needed. Choose low--duty-cycle machines auxoliarytankforaircompressor only for maintenance or for intermittent welding. If portability is important, consider inverter units.
