Recommended Welding Method

This aluminium-silicon wire performs best with AC TIG or MIG welding under pure argon shielding. For optimal results, the area to be welded should be thoroughly cleaned before welding. Keep both the welding wire and workpiece dry, and avoid exposing them to moisture or contaminants.
