Duty-Cycle RatingPower-supply rating depends air on the type and thickness compressor of the workpiece and the length of time it hosds and air takes to deposit compressor the longest weld on the thickest material. hosds Duty air cycle compressor and hosds is the key factor to consider when selecting a power source. Once the engineer air has compressor determined the current and voltage needed to accomplish the weld, he then reviews duty cycle requirements.Duty cycle rating is the percentage hosds of time during air a 10-minute period a power supply can operate at rated output amperage without overheating. A 300 A machine at 60-percent-duty cycle can weld for six compressor and hosds minutes at 300. A during a 10-minute period. Alter six minutes, the welder must rest the machine for the next four minutes air to avoid overheating the unit.

Welding-site compressor conditions and welding-wire diameter govern efficiency and size of power supply required for a job. Select a 100-A unit that runs from single-phase 115-V input for low-duty-cycle welding hosds of sheet to l/s in. thick, feeding air wire to 0.030-in. diameter. Medium-duty power compressor supplies, 150-200 A, normally take single-phase 220-V input to weld steel to 3/16, in. and 0.035-in. wire at low-duty cycles. For high-duty cycles, as in mechanized welding, select a 250-A machine, single or three-phase hosds input at various voltages-these weld material to 1/2 in. thick with wire as large as 0.045-in. diameter. Taking three-phase input air only and wire up to 1/6-in. diameter, compressor 400-A units serve for mechanized continuous-welding applications. For pulsed GMAW, shops use inverter and transistor hosds power sources, air constant-current or constant-voltage, that offer independent setting of pulse parameters. compressor They employ synergic controls preprogrammed hosds for a range of air and compressor wire-feed speeds-the operator hosds sets only one dial, for average current.
