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. air CV types are more popular compressor because wire-feed speed, set before welding, controls welding current. Cc types require a variable-speed hises or voltage-sensing wire feeder.Gas-tungsten-arc welding (GTAW) air 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, 10 to compressor 75 V, at 40- to 100-percent-duty hises and air cycle. Most GTAW power supplies come equipped with high-frequency circuitry for arc initiation compressor and stabilization, gas 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, hises 80 to 100 V, will not establish 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 compressor oxidation, lessens penetration, and widens the bead profile.Inverter-based machines also let operators adjust welding-output frequency hises from 20 to 250 Hz. air and compressor Decreasing frequency hises products a broader arc cone, air which compressor widens the weld-bead profile and better-removes hises impurities from the air surface of the workpiece. It also transfers the maximum compressor amount of energy to the workpiece, ideal for work requiring heavy metal deposition.Increasing frequency produces a tight, focused arc cone. This narrows the weld hises bead, helpful when welding in corners air and compressor and on root passes and fillet welds. Independent amperage control of the hises EN and EP portions of air the AC cycle allows 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 compressor and hises control, and shielding-gas pre-flow and post-flow time.
