In some instances, consider adding helium to the shielding gas mixture for its ability to provide a hotter, more penetrating arc on thicker sections. For the GMAW process, a mixture of 75 percent helium balanced with 25 percent argon is a good option.inally, consider purchasing low-dew-point shielding gases as protection against porosity. Follow all recommended welding procedures for shielding gas flow rates and purge cycles. As with any welding process on any material, following some basic guidelines is critical to obtaining the best results.
When using compressed gases, wear. appropriate protective equipment, such. as safety goggles or face shield, rubber. gloves, and safety shoes. Well-. ventilated barricades should be used in. extremely hazardous operations, such. as in the handling of fluorine. Gas masks should be kept available for immediate use when working with toxic gases. These masks should be placed in convenient locations in areas not likely to become contaminated, and should be approved by the U.S. Bureau of Mines for the service intended. Those involved in the handling of compressed gases should become
