 For flux-cored-arc welding, shops use CV or CC types, air 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 (AC or DC) power supply with a steep volt-amp curve to minimize current compressor change accrssory 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 air and stabilization, gas valves, and cooling-water valves for high-current welding. High-frequency arc compressor start is useful when the maximum open-circuit voltage allowed by NEMA standards, 80 to 100 V, will not establish and maintain accrssory a stable air arc. * Reduces the size of the etched zone compressor for improved cosmetics.Less EN time improves cleaning action to remove heavier oxidation, lessens penetration, and widens the bead profile.Inverter-based machines also let operators adjust welding-output frequency from 20 to 250 Hz. Decreasing frequency products a broader arc cone, which accrssory widens the weld-bead air profile and better-removes impurities compressor from the surface of the workpiece. It also transfers the maximum amount of energy to the workpiece, ideal for work requiring heavy metal deposition.Increasing frequency accrssory produces a tight, air focused arc cone. This narrows the weld bead, helpful when welding in corners and on root passes and fillet welds. Independent amperage control of the EN and EP portions of the AC cycle compressor 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 control, accrssory and shielding-gas pre-flow and post-flow time.
