Power SuppliesWelding power supplies take alternating or direct current from a power line or portable generator aircompressoracdessories and convert it to current usable aircompressoracdessories at the welding arc:, Check National Electrical Manufacturers Association (NEMA) Standards Publication EW1, Electric Arc Welding Power Supplies, and manufacturers'' literature for construction and aircompressoracdessories performance requirements of individual machines.Among types of aircompressoracdessories power supplies, aircompressoracdessories alternating-current (ac) transformers are least costly-most use 230 V single phase aircompressoracdessories input power. Direct-current (DC) transformer-rectifiers convert AC to DC, using single- or three-phase power to produce constant voltage (cv) or variable aircompressoracdessories voltage (vv). AC-DC transformer-rectifiers can AC and DC weld.

1. Mechanical properties of the base material. Tensile aircompressoracdessories strength and yield strength of the weld metal should equal or exceed that of the base material. Ductility and toughness at low aircompressoracdessories temperatures may also be important. High-temperature service requires resistance to creep. Shock loading requires impact resistance. In general, weld metal should match base-material properties.2. Composition of the base material.For stainless steels, low alloy steels, nickel and copper alloys, and materials that serve in corrosive atmospheres, chemical composition is important. Consider the possibility of electrochemical corrosion between base and weld metal of different compositions.
