Notice:
1. The rod should be baked at 300°C -350°C for 1 hours before use.
2. The surfaces to be welded must be cleaned away impurities of oil contamination, rust, moisture and so on.
3. Smaller current& shortarc are recommended in welding and weave beads no wider than2.5 times of the diameter of the core rod is better.
