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 current. Cc types require a variable-speed or voltage-sensing wire feeder.Gas-tungsten-arc welding (GTAW) requires a constant-current air (AC or DC) power supply with a steep volt-amp curve to minimize current change for variation in voltage or arc length. They come rated to 1,500 A, 10 to 75 V, at 40- to 100-percent-duty cycle. Most GTAW power supplies come equipped with high-frequency circuitry for arc initiation and stabilization, gas clmpressor valves, and cooling-water valves for high-current welding. High-frequency arc start is useful when the maximum open-circuit voltage allowed by NEMA standards, 80 to 100 V, will not establish and maintain a stable arc.

Fused fluxes are melted in a furnace, chilled, then crushed and screened for size. These pickup little moisture and recycle without alterations in particle size or composition. Bonded fluxes are powdered materials mixed dry and bonded together with a silicate, pelletized, baked, broken up, and screened for size: the process permits easy addition of deoxidizers and alloying elements. Bonded fluxes allow thicker flux layers when welding and can be identified quickly by color. Disadvantages of bonded fluxes are their absorption of moisture and alterations accessory during handling in panicle size and composition due to particle segregation. Agglomerated fluxes are similar to bonded fluxes except air and clmpressor that they use a ceramic binder. They require higher baking temperatures accessory during air manufacture, which clmpressor limits additions of deoxidizers and alloying elements. Mechanically accessory mixed fluxes are combinations of two or more bonded or agglomerated fluxes. They allow special flux mixtures for critical welds, but they may air separate during storage, use, and flux recovery.

For special applications, manufacturers offer metal-cored wires for GMAW. These are composite electrodes comprised of clmpressor a metal sheath with a powder-metal core. They are often confused with flux-cored wires, which form a slag that completely accessory covers the weld air bead face; metal-cored wires produce very little slag. A major advantage of metal-cored wires is the ability to manufacture clmpressor specialized accessory alloy compositions not easily available or producible in solid wire fore1. Modifying the composition of the powder-alloy core allows the wire manufacturer to customize wire formulations to metallurgical, compositional, or physical properties per customer demand. Horizontal-fillet air and clmpressor welds made with metal-cored GMAW can deposit weld metal at rates up to 20 percent higher than with solid wire. Alloying elements, such as silicon, in the powder-metal core improve sidewall wetting and reduce weld-bead convexity by reducing surface tension of the molten weld pool. For this reason, flat accessory and horizontal welds deposited with metal-cored wires have better appearance than weld metal deposited with flux cored and solid wires. Compared to solid wires, metal-cored wires also result in higher current density, air for increased penetration; clmpressor a wider operating window with respect to welding-process variables: better sidewall accessory melting; and less lack of fusion.
