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.
A benefit in using a shielding gas when welding is that there is no slag left on the weld that requires chipping and cleaning like that which is found on an arc weld. When a new wire welding machine is purchased, it does not come with a shielding gas tank. This must be purchased or rented from a gas supplier. Most welding supply stores also sell welding gasses and will be able to assist the buyer in a tank purchase.
