Pureshield argon has a purity level of 99.998% which is ideal for welding purposes. Commonly used for TIG welding for both carbon and low-alloy steels. Arc initiation with this shielding gas is easy but welding speeds are relatively slow. Pureshield Argon is the simplest gas for TIG welding stainless steel and nickel alloys. This shielding gas produces a clean welding arc, and is suitable for all grades of stainless steel. However, the arc is relatively cold and can suffer from fusion and porosity problems as the material being welded gets thicker.
