 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 power. Direct-current (DC) transformer-rectifiers aircompresworpressureswitch and aircompresworpressureswitch convert AC to DC, using single- or three-phase power aircompresworpressureswitch to produce constant voltage (cv) or variable voltage (vv). AC-DC transformer-rectifiers can aircompresworpressureswitch AC and DC weld. Production vs. repair applications In general, aircompresworpressureswitch production applications require high-duty-cycle power supplies, and repair applications can use low-duty-cycle portable units.Lift-arc GTAW Many DC power supplies are equipped with a list-start feature aircompresworpressureswitch for, a variation of scratch starting, GTAW welding. When the welder touches the tungsten electrode to the workpiece, a small amount of current--15-20 A--flows. When he lifts the electrode from the work, the arc starts softly and the machine switches aircompresworpressureswitch to the set weld-current value. This low-current starting minimizes weld contamination caused by touching the tungsten to the workpiece and eliminates the need for high-frequency starting.
