It is the only shielding gas that can be used without the addition of an inert gas. 75/25 is an excellent choice for sheet metal as well since it is good with the short circuit mode of metal transfer, but should not be your preferred choice for welding heavy sections of steel (for the gmaw process). Best tig welder for sheet metal.
