 Welding-site conditions and welding-wire diameter govern efficiency and size of power supply required 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, portable air tank parts 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, single or three-phase input at various voltages-these weld material to 1/2 in. thick with wire as large as 0.045-in. diameter. taking tank three-phase input only and wire up to 1/6-in. diameter, 400-a units serve for mechanized continuous-welding parts applications. for pulsed gmaw, shops use inverter and transistor power sources, constant-current or constant-voltage, that offer independent setting of pulse parameters. they employ synergic controls preprogrammed for a range portable of wire-feed speeds-the operator sets only one dial, for average current. fused fluxes are melted in a furnace, chilled, then crushed and screened for size. these pickup little moisture and recycle without alterations in particle size or composition. bonded fluxes are powdered materials mixed dry and bonded together with a silicate, pelletized, baked, broken up, and screened for size: the process permits air easy addition of deoxidizers and alloying elements. bonded fluxes allow thicker flux layers when welding and can be identified quickly by color. disadvantages of bonded fluxes are their absorption of moisture tank and parts and alterations during handling portable in panicle size and composition due air to particle segregation. tank and parts agglomerated portable fluxes are similar to bonded fluxes except that they use a ceramic binder. they require air higher baking tank temperatures parts during manufacture, which limits additions of deoxidizers and alloying elements. mechanically mixed fluxes portable are combinations of two or more bonded or agglomerated fluxes. they allow special flux mixtures for critical welds, but they may separate during storage, use, and flux recovery. for air special applications, manufacturers offer metal-cored wires for gmaw. these are composite electrodes comprised of a metal sheath tank with a powder-metal core. they are often confused with flux-cored wires, which form a slag that completely covers the weld bead parts face; metal-cored portable wires produce very little slag. a major advantage of metal-cored wires is the ability to manufacture specialized alloy compositions not easily available or producible in solid wire fore1. modifying the composition of the powder-alloy core allows the wire manufacturer to customize wire air formulations to metallurgical, compositional, or physical properties per customer demand. horizontal-fillet welds made with metal-cored gmaw can deposit weld metal at rates up to 20 percent higher than with solid wire. alloying elements, such as silicon, tank in the powder-metal core improve sidewall wetting and reduce weld-bead parts convexity by reducing surface tension of the molten weld pool. for this reason, flat and horizontal welds deposited with metal-cored wires have better appearance than weld metal deposited with flux cored and solid wires. compared portable to solid wires, metal-cored air wires also result in higher tank current density, for increased penetration; a wider operating window with respect to welding-process variables: better sidewall melting; and less lack of fusion parts.
