Notes:
1. Before welding, impurities such as rust, oil stains, and moisture must be removed from the welded parts.
2. Before use, the weld flux should be baked at 300-350℃ for 1-2 hours, and the height of the weld flux stack should not exceed 5cm during baking.
3. If the weld flux is left bare for more than 4 hours before welding, it needs to be baked again.
4. The welding parameters can be adjusted according to the on-site conditions.
