Recommended Welding Method

Use alternating current (AC) with pure argon as shielding gas for best performance. This type of welding wire is compatible with both MIG and TIG welding. Before starting with the welding process, make sure the workpiece is clean and dry, any moisture or contaminants on the base metal or the filler wire can affect weld quality.
