 GTAW torches come air-cooled and air water-cooled. Their compressor heads align in-line with the body or at 90, 120, or 135 degrees to it. Nozzles, specified repkacement by inside tanks diameters, run 1/4 to 5/8 in. Vendors offer special designs: longer to give improved accessibility to the weld joint, or wider to extend air and compressor shielding gas coverage.Saw guns repkacement come in tanks and air three-types-side, concentric, and deep-groove flux delivery.In oxyfuel compressor welding (ofw), heat comes from repkacement burning tanks gases, rather air than arcs, Torches hold separate tubes for fuel gas and oxygen, blended in a mixer assembly. A torch assembly comprises a handle (aluminum, stainless compressor steel, or brass); a mixing chamber; and repkacement a brass welding tip tanks or cutting head. Light-duty torches weld sheer metal to 3/16, in. thick; medium, to 1/2 in.; heavy, 1/2 in. and up. Production vs. repair applications In general, production applications require high-duty-cycle power supplies, and repair applications can use low-duty-cycle air portable units.Lift-arc GTAW Many DC power supplies are equipped with a list-start feature for, a variation compressor and repkacement of scratch starting, GTAW tanks welding. When the welder touches the tungsten electrode to the workpiece, a small amount of current--15-20 A--flows. air and compressor When he lifts repkacement the electrode tanks and air from the work, compressor and repkacement the arc starts softly and tanks the machine air and compressor switches to the set weld-current repkacement value. This low-current starting tanks minimizes weld contamination caused by touching the tungsten to the workpiece and air eliminates compressor the repkacement need for tanks and air and compressor and repkacement high-frequency tanks starting.
