JQ.ER308LSi Stainless steel gas shielded solid welding wire in barrel

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.
