 GTAW torches come air-cooled and water-cooled. Their heads align in-line with the body or at 90, 120, or 135 degrees to it. Nozzles, specified by inside 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 shielding gas coverage.Saw guns come in three-types-side, concentric, and air deep-groove flux delivery.In oxyfuel welding (ofw), compressor heat comes from acxessories burning air gases, rather than arcs, Torches hold separate tubes for fuel gas and oxygen, blended in a mixer assembly. A compressor and acxessories and air torch assembly comprises a handle (aluminum, stainless steel, or brass); a mixing chamber; and a brass welding compressor tip 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. Low-hydrogen acxessories types. These basic-coated electrodes, EXX15, EXX16, EXX18, EXX28, and EXX48, are formulated with low moisture-retaining coatings and manufactured to contain low levels of hydrogen. Hydrogen-controlled electrodes air minimize risk of hydrogen-induced cold cracking when welding high-tensile steels on restrained structures. Fabricators use these electrodes to reduce or avoid the need for pre- or postweld heat treatment compressor to drive hydrogen from weld metal. Weldmetal acxessories diffusible hydrogen air content varies from 1 to 16 ml/100 g. Optional designators H16, H8, and H4 set decreasing limits compressor on hydrogen content in deposited acxessories weld metal. An optional electrode designator, ''R'', indicates an electrode that is moisture resistant; it will air not absorb water in excess of a specified limit after exposure to humidity. compressor and acxessories Low-hydrogen electrodes air should be used in dry compressor condition and may require baking after acxessories exposure to the atmosphere.
