Notes:
1. Using mixed gas protection, gas code M21 (Ar+(15-25%) CO₂).
2. The dry extension length of the welding wire should be controlled within the range of 15-20mm.
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.
When welding on site, if the wind is too strong, windproof measures should be taken.
