 Mix air recovered flux before reusing to maintain its manufactured properties. Three-parts new flux mixed with one-part recovered flux works well. Consult the flux manufacturer for proper proportions.Fluxes classify as basic, acid, or neutral. Fluxes that contain oxides and break up easily during welding are basic. These provide oxidizing action and alloy with the weld metal to obtain desired mechanical properties. Acidic oxides break up slightly, for the same reasons. Welding voltage compressor must remain within the adcessory and air range specified by the manufacturer of acidic and basic fluxes. Excessive arc voltage reduces the alloying of flux constituents with the weld metal. Neutral fluxes do not oxidize alloying elements or add compressor alloying elements to the weld. As amperages increase, flux adcessory particle size should decrease. Excessive current for a particle size produces unstable art''s and uneven weldbead edges. Welding-site air conditions and compressor and adcessory welding-wire diameter govern efficiency and size air of power compressor supply required adcessory for a job. Select a 100-A unit that runs from single-phase 115-V input for low-duty-cycle welding of sheet to l/s in. thick, feeding wire to 0.030-in. diameter. Medium-duty power 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 air cycles, as in mechanized welding, select a 250-A machine, compressor single or three-phase adcessory input at various voltages-these weld material to 1/2 in. thick with wire air and compressor as large as 0.045-in. diameter. Taking three-phase input only and wire up to 1/6-in. diameter, 400-A units serve for mechanized continuous-welding adcessory and air applications. For pulsed GMAW, compressor shops use inverter and transistor power sources, constant-current or constant-voltage, that offer independent setting of pulse adcessory parameters. They employ air synergic controls preprogrammed for a range of wire-feed speeds-the operator sets only one dial, for compressor average current adcessory.
