Notes:
1. Using CO₂ gas protection, the purity of CO₂ gas is above 99.8%.
2. The dry extension length of the welding wire should be controlled within the range of 15-25mm.
3. Before welding, impurities such as rust, oil stains, and moisture must be removed from the welded parts.
4. After unpacking the wire, attention should be paid to taking moisture-proof measures and using it up as soon as possible.
5. When welding on site, if the wind is too strong, windproof measures should be taken.
