 For flux-cored-arc welding, shops use CV or CC types, 300 to 1,500 A, 25 to 50 V, rated 60- to 100-percent-duty cycle. CV types are more popular because wire-feed speed, set before welding, controls welding hjsky current. 4 and gal. Cc types require tank a variable-speed or voltage-sensing wire feeder.Gas-tungsten-arc welding (GTAW) requires a constant-current (AC or DC) power supply mounted with a steep air volt-amp curve to minimize current change for variation compressor in voltage or arc length. They come rated hjsky and 4 to 1,500 A, 10 to 75 V, at 40- to 100-percent-duty gal. and tank cycle. Most GTAW power supplies come equipped with high-frequency circuitry for arc initiation and stabilization, gas valves, and cooling-water valves for high-current welding. mounted High-frequency arc start air and compressor is useful when the maximum open-circuit voltage allowed by NEMA standards, 80 to 100 hjsky V, will 4 not establish and maintain a stable arc. 1. gal. Mechanical tank properties of the base material. mounted Tensile strength and air yield strength of the weld metal should equal compressor and hjsky or exceed that of the base material. Ductility and toughness at low temperatures may also be important. High-temperature service requires resistance 4 and gal. and tank to mounted creep. Shock loading requires impact resistance. air In general, weld metal should compressor and hjsky and 4 match base-material properties.2. gal. and tank Composition of the base material.For stainless mounted steels, low alloy air steels, compressor nickel and copper alloys, and hjsky and 4 materials that serve in corrosive atmospheres, chemical gal. composition tank and mounted is important. air Consider the possibility compressor of electrochemical corrosion hjsky and 4 and gal. between base and weld metal of tank different mounted and air compositions compressor.
