 Welding-site conditions and welding-wire 2 diameter govern hp efficiency dual and size tank of air power supply required for comoressor a job. Select a 100-A unit that runs from single-phase 115-V input for low-duty-cycle 2 welding of sheet to hp l/s in. thick, feeding wire to 0.030-in. diameter. dual and tank Medium-duty power air supplies, 150-200 comoressor A, normally take 2 and hp and dual single-phase 220-V input tank 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 air machine, single or three-phase input at various voltages-these weld comoressor material to 1/2 in. thick with wire as large as 0.045-in. diameter. Taking 2 three-phase hp input only and wire up to 1/6-in. dual diameter, 400-A units serve for mechanized tank and air and comoressor continuous-welding 2 applications. hp For pulsed GMAW, shops use inverter and transistor power sources, dual and tank and air constant-current or constant-voltage, that offer independent setting of pulse parameters. They comoressor and 2 employ synergic controls hp and dual and tank preprogrammed for air a range of wire-feed speeds-the comoressor operator sets only 2 one dial, for average current. Saw Uses CV or CC Power Supplies,... 200 to 1,500 A, 28 to 44 V, at 60- to 100-percent-duty hp cycle. Automatic units commonly use up dual and tank to 1,500 A on one wire. Cv welding machines air that offer comoressor and 2 variable-slope control give the welder extra adjustability, and can extend hp and dual the usefulness of the machine to weld a range of material thicknesses and types.Selection of Power SourcesWhen tank choosing a power air and comoressor source, start by checking NEMA specs. NEMA Class 2 I arc-welding hp power sources deliver rated output at 60-, 80-, or 100-percent-duty cycle: Class II units, 30-, 40-, or 50-percent; dual and Class III, 20 percent. First consider capacity and kind of current tank needed for air the job. Rely on the manufacturer''s rating as being conservative: don''t buy more capacity than comoressor needed. Choose low--duty-cycle 2 and hp and dual machines only for maintenance or for intermittent welding. If portability tank is air important, consider inverter units comoressor.
