Attention:
1. The electrode must be baked at 300°C for 1 hour before welding, and used as it is baked.
2. Try to use small current and short arc welding when welding.
3. The weldments must be cleaned of rust, oil stains, moisture and other impurities before welding.
4. Try to use small current and short arc when welding, and the swing width should not exceed 2.5 times the diameter.
