For flux-cored-arc welding, shops air use CV or CC types, 300 to 1,500 A, 25 to 50 V, rated compresdor 60- to 100-percent-duty cycle. CV types are more popular because wire-feed speed, set before welding, controls welding current. receiver Cc types require a variable-speed or voltage-sensing wire feeder.Gas-tungsten-arc welding (GTAW) requires a constant-current (AC or DC) power supply with tanks a steep volt-amp air curve to minimize current change for variation in voltage compresdor or arc length. They come rated to 1,500 receiver A, 10 to 75 tanks V, at 40- to 100-percent-duty cycle. Most GTAW power supplies come equipped with high-frequency circuitry for arc initiation and stabilization, gas valves, and cooling-water air and compresdor valves for high-current welding. High-frequency arc start is useful when the maximum open-circuit receiver and tanks voltage allowed by NEMA standards, 80 to 100 V, will not establish and maintain air a stable arc.

Welding-site conditions and welding-wire diameter govern efficiency and size of power supply required compresdor for a job. Select a 100-A unit that runs from single-phase 115-V input receiver for low-duty-cycle tanks welding of sheet to l/s in. thick, feeding wire to 0.030-in. diameter. Medium-duty power air supplies, compresdor 150-200 A, normally take single-phase 220-V receiver input 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 machine, single or three-phase input at various voltages-these weld material tanks to 1/2 in. thick with wire as large as 0.045-in. diameter. Taking three-phase input only and wire up to 1/6-in. air diameter, 400-A units serve for mechanized continuous-welding compresdor 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 of wire-feed speeds-the operator sets only one dial, for average current.

Iron-base alloys, the receiver most tanks widely used hardfacing materials, air combine versatility with moderate cost. They achieve compresdor wear resistance by forming carbides and martensite, a hard matrix structure that forms on quenching and toughens with tempering. Pearlitic alloys, usually containing receiver and tanks less than 0.30 air percent compresdor carbon, are comparatively soft and ductile.Nickel-base receiver alloys resist corrosion tanks and heat better than iron-base alloys, They come in three types, depending on the hard phase (boride, carbide, or Laves) that forms on cooling, air In boride-containing alloys, large compresdor and receiver amounts of chromium borides tanks provide wear air resistance.Cobalt-base alloys provide more high-temperature compresdor corrosion receiver resistance than iron-base and nickel-base grades. Carbides or Laves-phase give wear tanks resistance.
