Precautions for product use
1. Shielding gas: Pay attention to the purity of the shielding gas, and the recommended gas mixture ratio is Ar+1-3%O2.
2. Gas flow: 20-25L/min.
3. Dry elongation: 15-25mm.
4. Really remove the rust layer, moisture, oil, dust, etc. on the welding part.
5. During outdoor welding, when the wind speed is greater than 1.5m/s, windproof measures should be taken, and appropriate windproof measures must be taken to prevent the occurrence of blowholes.
The above suggestions are for reference only, and the actual situation shall prevail in the specific operation. If necessary, process qualification should be carried out before determining the welding plan.
