  • Stainless Steel MIG Welding with Compact Welders

    In general, the grade of wire you use depends on the type of stainless steel base material you are welding. The three most common grades of austenitic stainless steel wires are 308, 309 and 316. These wire grades may also have a "L" designator, indicating that the wire's carbon level falls in the low end of the carbon range.
