 Power SuppliesWelding power air supplies take alternating or direct current from a power line or portable compressor generator and convert it acdessory to current usable at air the welding arc:, Check National Electrical Manufacturers compressor Association (NEMA) acdessory Standards Publication EW1, Electric Arc Welding Power Supplies, and manufacturers'' literature for construction air and performance requirements of individual machines.Among types of power compressor supplies, alternating-current (ac) transformers acdessory are least costly-most use 230 V single phase input power. Direct-current (DC) transformer-rectifiers convert AC to DC, using single- or three-phase power to produce constant voltage (cv) or air and compressor variable voltage (vv). acdessory AC-DC transformer-rectifiers air can AC and DC weld. Hardfacing alloys contain as base elements typically iron, nickel, or cobalt, compressor to which metallurgists acdessory add varying amounts of carbon, chromium, molybdenum, tungsten, silicon, manganese, vanadium, and boron. To raise hardness, the primary air property compressor and acdessory and air for wear resistance, alloy designers add elements compressor that either form hard constituents (carbides, acdessory borides, or Laves phase), or that strengthen air the matrix by going into solid compressor solution. Carbon content determines toughness and abrasion resistance--as acdessory carbon rises, abrasion resistance increases and toughness drops. Chromium air forms carbides, increases corrosion resistance, compressor and adds high-temperature acdessory and air strength. Tungsten, a potent carbide former, also boosts high temperature strength, as does cobalt. compressor Tougheners include nickel and manganese. Boron acdessory forms hard wear-resistance borides.
