    O-1 (99% argon/1% oxygen) is used for stainless steels. Oxygen stabilizes the arc. Argon-helium A-25 (25% argon/75% helium) is used for nonferrous base when higher heat input and good weld appearance are needed. A-50 (50% argon/50% helium) is used for nonferrous metals thinner than 0.75 inch for high-speed mechanized welding.

    TIP TIG welding torch. TIP TIG is a subset of gas tungsten arc welding (GTAW), using a mechanism called filler wire agitation to enhance molten weld pool dynamics. This agitation has been found to enhance the weld puddle fluidity and release evolving gases, reducing the chances of inclusions and porosity, and also separate impurities.

  7. Gas tungsten arc welding - Wikipedia

    en.wikipedia.org/wiki/Gas_tungsten_arc_welding

    GTAW weld area. Manual gas tungsten arc welding is a relatively difficult welding method, due to the coordination required by the welder. Similar to torch welding, GTAW normally requires two hands, since most applications require that the welder manually feed a filler metal into the weld area with one hand while manipulating the welding torch in the other.
