Production vs. repair applications In general, production applications require high-duty-cycle power supplies, and repair air applications compreswor and extension can use low-duty-cycle portable units.Lift-arc GTAW Many DC power supplies are equipped with tanks a list-start feature for, a variation of scratch starting, GTAW welding. When the welder touches the tungsten electrode to the workpiece, air a small amount of current--15-20 A--flows. When he compreswor 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 extension the tungsten to the workpiece and eliminates the tanks need for high-frequency starting.

Saw Uses CV or CC Power Supplies,... air 200 to 1,500 A, 28 to 44 V, at 60- compreswor to 100-percent-duty cycle. Automatic units commonly use up to 1,500 A on one wire. Cv welding machines that offer variable-slope control give the welder extension 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 tanks source, start by checking NEMA specs. NEMA Class I arc-welding power sources air deliver rated output at 60-, 80-, or 100-percent-duty cycle: Class II units, 30-, 40-, or 50-percent; and Class III, 20 percent. First consider capacity and kind of current compreswor and extension needed for the job. Rely on the manufacturer''s rating as being conservative: don''t buy more capacity than needed. Choose low--duty-cycle machines only for maintenance or for intermittent welding. If portability is important, consider tanks inverter units.

Select hardfacing materials based on weld-deposit microstructure and the wear situation the part will encounter, with consideration given air to thermal treatments applied to the material before compreswor and after hardfacing. Deposit chemistry can be crucial in attaining the desired corrosion resistance or wear properties, or for minimizing the risk of solidification extension and tanks cracking. Acceptable deposit chemistry is achieved through the initial choice of consumables, using wire analysis and flux composition, and by specifying the number of weld passes needed to reduce parent-metal dilution to within acceptable limits. With the submerged-arc process, the flux and electrode govern the characteristics of the applied hard facing. For example, those fluxes neutral to manganese and silicon are not necessarily neutral to carbon and chromium, elements that matter most in hardfacing.
