Notes: 1. The electrode must be baked at 300 ° C for 1H before welding. 2. DC power supply should be used as far as possible, the current should not be too large. 3. Before welding the welding parts must be removed oil, rust, moisture and other impurities. Four. When welding, small current and short arc should be used as far as possible, swing width should not exceed 2.5 times of diameter
