Notice:
- To avoid rust the wire must be kept in dry condition and keep the package in good condition also before welding.
- To avoid welding defect the shield gas should be pure particularly no moisture in it.
- The surfaces to be welded must be cleaned away impurities of oil contamination, rust, moisture and so on.
- 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.
