Electrodes come 3 to 24 in. long, 0.01 to 0.25-in. diameter. Colored markings--bands or dots--indicate composition: air pure comoressor tungsten, green; 1-percent thoriated, yellow; 2 percent thoriated. red; ceriated, orange; lanthanted, black.Filler metal tanks GIAW does not usually requite addition of fillet metal, but filler is commonly added when base-metal thickness is greater than houston 1/8 in. Finer metal for low-carbon (to 0.15 C) and mild (0.15 m 0.29 C) steels are described in AWS A5.2; for carbon steel in A5.18; and for texas low-alloy steels in A5.28 Flux. AWS air specifications A5.17 and A5.23 describe fluxes for saw. AWS designation of fluxes precedes that of the wire when identifying a combination for a welding procedure. For example, the designation comoressor F7A2-EM12K indicates a flux (F) that will provide, tanks with a given wire designation, tensile strength of 70,000 Psi (7), in the as-welded condition (A), and impact properties of 20 ft lb at -20 F (2). A designation houston containing a P rather indicates the flux properties texas after postweld heat treatment.

Low-hydrogen types. These basic-coated electrodes, EXX15, EXX16, EXX18, air EXX28, and EXX48, are formulated with low moisture-retaining coatings comoressor and tanks manufactured houston to contain texas low levels of hydrogen. Hydrogen-controlled air electrodes minimize risk of hydrogen-induced cold cracking when welding high-tensile steels on restrained structures. comoressor Fabricators use these electrodes to reduce or avoid the need tanks for pre- or postweld heat treatment to drive hydrogen from weld houston metal. texas and air Weldmetal diffusible hydrogen content varies from 1 to 16 ml/100 g. Optional designators H16, H8, comoressor and H4 tanks and houston and texas set decreasing limits on hydrogen content in deposited weld metal. An optional electrode designator, air ''R'', indicates comoressor an electrode that is moisture resistant; it will not absorb water in excess of a specified limit after exposure to humidity. Low-hydrogen electrodes should be used in dry condition and may require baking after exposure tanks and houston to texas the atmosphere.

Production vs. repair applications In general, production applications require high-duty-cycle power supplies, and air repair applications can use low-duty-cycle portable units.Lift-arc GTAW Many DC power supplies are equipped with comoressor and tanks a list-start feature for, 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. houston When he lifts the electrode from the work, the arc starts softly and the machine switches texas 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.
