 Features and OptionsPower supplies are capable to "talk to each other," useful when a company" wants to input the same welding procedures into several aor machines tanks at once or monitor the welding consistency and performance of several machines from a single location-through serial-data communications. Fabricators can take some of their machines and connect them to a personal computer to compressors monitor performance, and download welding parameters to the machines from it memory card for fast setup. High-end machines will calculate the pounds of weld wire used per machine. The machine can also be prepped to constantly monitor and average the welding aor current and voltage used, so that fabricators can set limits on the machine and track how many times welding parameters fell in or out of these limits. Production vs. repair applications In general, production applications require high-duty-cycle power supplies, and repair applications can use tanks and compressors low-duty-cycle portable units.Lift-arc GTAW Many DC power supplies are equipped with a list-start feature for, aor a variation of scratch starting, GTAW welding. When the welder touches the tungsten electrode to the workpiece, a small amount of current--15-20 A--flows. When he 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 need for high-frequency starting. * Reduces the size of the etched zone for improved cosmetics.Less EN time improves cleaning action tanks 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 compressors frequency products a broader arc cone, which widens the weld-bead profile and better-removes impurities from the surface of the workpiece. It also transfers the maximum amount of aor energy to the workpiece, tanks ideal for work requiring heavy metal deposition.Increasing compressors frequency produces a tight, 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 allows the operator to fine-tune the amount of aor energy directed into the workpiece, as well as take heat off of the tungsten electrode. tanks and compressors A basic, professional-quality aor AC GTAW power supply lets the operator adjust for variables: amperage, tanks balance control, compressors and shielding-gas pre-flow and post-flow time.
