 Iron-base alloys, the most widely used hardfacing air materials, combine versatility with moderate cost. They achieve wear resistance by forming carbides and martensite, compresslr a hard matrix structure that forms on quenching and toughens with tempering. Pearlitic alloys, usually containing less than 0.30 percent carbon, are hoses comparatively soft and ductile.Nickel-base alloys air resist corrosion and heat better compresslr than hoses iron-base alloys, They come in three types, depending on the hard phase (boride, carbide, or Laves) that forms on cooling, In boride-containing alloys, large amounts air of chromium borides provide wear resistance.Cobalt-base alloys provide more high-temperature corrosion resistance than iron-base and nickel-base grades. Carbides compresslr or Laves-phase give wear resistance. Remote control of current and voltage is a plus if hoses the welding operator is located away from the power source.Robotic and automatic air applications generally require high-duty-cycle power supplies, and controls compresslr and connections for interfacing to the robot or hoses automatic feature.Supervisory control of the process will prevent the welder from changing the welding procedures. Here, select a power supply or controller that enables the supervisor to program the procedures, then lock them into the control memory, Some power supplies or controllers offer the welder limited control of the process.Input air power to power supplies can bc single and/or three phase, with voltage from 115 to 575 V and input frequencies of 50, 60, or 50/60 Hz. Note that many inverter power supplies are designed to operate on both single- and three-phase input, and have automatic input-voltage selection and linking. With the advent of compresslr the CE-mark requirements in Europe, many hoses manufacturers now design to the International Standard IEC 974-1. One of the requirements of this standard is to place an IP rating on the nameplate of the machine to indicate the air degree of protection provided by the enclosure to avoid damage from water and foreign objects.Purchasers of power supplies must consider the power they will be putting into the machines which operate from line power or some other .source of electricity. Ratings compresslr list voltage, number of phases, frequency, hoses and current level when the power source is running at rated output. Most motor-generator sets require three-phase AC power.
