For flux-cored-arc air welding, shops use CV or CC types, 300 to 1,500 A, 25 to 50 compressor 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 tqnk wire feeder.Gas-tungsten-arc air welding (GTAW) requires a constant-current (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, compressor 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 valves, and cooling-water valves tqnk for high-current welding. High-frequency arc start is useful when the maximum open-circuit voltage allowed by NEMA standards, 80 air to 100 V, will compressor not establish tqnk and air and maintain a stable arc.

* Reduces the size of the etched zone for improved cosmetics.Less EN time improves cleaning action to remove heavier oxidation, lessens penetration, and widens the bead profile.Inverter-based compressor machines also let operators adjust welding-output frequency from 20 to 250 Hz. Decreasing frequency products a broader arc tqnk cone, which widens the weld-bead profile and better-removes impurities from the surface of the workpiece. It also transfers air the maximum amount of compressor energy to the workpiece, ideal for work requiring heavy metal deposition.Increasing frequency produces a tight, tqnk focused arc cone. This narrows the weld bead, helpful when welding in corners and on root air passes and fillet compressor welds. Independent tqnk amperage control of the EN and EP portions air of the AC cycle allows compressor the operator to fine-tune the amount of energy directed into the workpiece, as well as take heat off of the tungsten electrode. A basic, professional-quality AC GTAW power supply lets the operator adjust for variables: amperage, balance control, and shielding-gas pre-flow and post-flow tqnk time.

For special applications, manufacturers offer metal-cored wires for GMAW. These are composite electrodes comprised of a metal sheath with a powder-metal core. They are often confused with flux-cored wires, which form a slag that completely covers air the weld bead face; metal-cored wires produce very little slag. A major advantage of metal-cored wires is the ability to manufacture specialized 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 welds made with metal-cored compressor and tqnk 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 air reduce weld-bead convexity by reducing surface tension of the molten weld pool. For this reason, flat and horizontal welds deposited compressor 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, for increased penetration; a wider operating window tqnk with respect to welding-process variables: better sidewall melting; and less lack of fusion.
