Welding precautions

1.Using CO2 shielding gas with purity ≥99.98% and gas flow of 20-25L/min.

2.Interpass temperature: 16~100°C.

3.During welding, please keep off wind to prevent welding defects caused by flying off shielding gas. Greasy dirt, water, etc. at welding parts shall be removed.

4.Welding wire shall be used up as quickly as possible after unpacking. Moisture-proof measures shall be adopted for those not used up.
