 Power SuppliesWelding power supplies take alternating or direct current from a power line or portable generator and convert it to current usable at the aircompressoraccdssories welding arc:, Check National Electrical Manufacturers Association (NEMA) Standards Publication EW1, Electric aircompressoraccdssories Arc Welding Power Supplies, and manufacturers'' literature aircompressoraccdssories for construction and performance requirements of individual machines.Among types of power supplies, alternating-current aircompressoraccdssories (ac) transformers are least aircompressoraccdssories costly-most use 230 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 variable voltage (vv). aircompressoraccdssories AC-DC transformer-rectifiers can AC and DC weld. Production aircompressoraccdssories vs. repair applications In general, production applications require high-duty-cycle aircompressoraccdssories power supplies, and repair applications aircompressoraccdssories can use low-duty-cycle portable units.Lift-arc GTAW Many DC power supplies are equipped with a list-start feature 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 to the set weld-current value. This low-current starting minimizes weld contamination caused by touching the tungsten to the workpiece and eliminates the aircompressoraccdssories need for high-frequency starting.
