Notice:1.To avoid rust the wire must be kept in dry condition and keep the package in good condition also                         before welding.

            2.To avoid welding defect the shield gas should be pure particularly no moisture in it.

            3.The surfaces to be welded must be cleaned away impurities of oil contamination, rust, moisture and                    so on.

            4. The welding conditions mentioned above for reference only and it is better to do a welding procedure                  qualification according to project before put it into formal welding .
