Managing the welding operation of the contractors business is a vital part of the total .Air Products Welder™s Handbook ARC WELDING Arc welding processes Fabrications involving sheet metal, plate or pipes are commonly welded by an arc process. Two of the most important processes use a gas shield to protect the weld metal from atmospheric contamination. Find below the MIG Welding Sheet Metal Settings Chart which displays the recommended settings for welding different gauge thicknesses of sheet metal. To ensure optimal results, select the appropriate gauge thickness and refer to the corresponding joint gap, wire diameter, amperage, and voltage setting for your weld.The welding of sheet metal with AC is less desirable than with DC. Arc conditions at low current levels required for thin materials are less stable on AC power than . Shielded Metal Arc Welding (SMAW) is the most extensively used manual welding method for general welding applications. It is frequently referred to as stick or covered
