 * Reduces the size of the etched zone for improved cosmetics.Less EN time improves cleaning action to remove heavier oxidation, lessens penetration, air and comprexsor widens the tank bead profile.Inverter-based air machines comprexsor and tank also let operators adjust welding-output frequency from 20 to 250 Hz. Decreasing frequency products a broader air and comprexsor arc cone, which widens the tank weld-bead air profile and comprexsor better-removes impurities tank from the surface of the workpiece. It also transfers air the maximum amount of energy comprexsor to the workpiece, tank ideal for air work requiring heavy metal deposition.Increasing frequency produces a tight, focused arc cone. This narrows comprexsor the weld bead, helpful when welding tank in corners and on root passes and fillet welds. Independent amperage control of the EN and EP portions of the AC cycle allows the operator to fine-tune the amount air of energy directed into the workpiece, as well as take heat off of the tungsten electrode. A basic, professional-quality AC GTAW power supply comprexsor lets the operator adjust for tank variables: air amperage, balance control, and shielding-gas pre-flow and post-flow time. Production vs. repair applications In general, production applications require high-duty-cycle power supplies, and repair applications can use low-duty-cycle comprexsor portable units.Lift-arc GTAW Many DC power supplies are equipped with a list-start feature for, a variation of scratch starting, GTAW welding. When the welder touches the tungsten electrode to the workpiece, tank a small amount of current--15-20 A--flows. When he air lifts the electrode from the work, the arc starts softly and the machine switches to the set weld-current value. This low-current starting minimizes weld contamination caused by touching the tungsten to the workpiece and eliminates the comprexsor need tank for high-frequency starting.
