Notes
1, welding electrodes shall be 150 °C baking 1 hour.
2, welding DC power supply as far as possible, because the AC welding penetration shallower. Current is not too large, so that Welding Rod red.
3, welded parts must be removed before welding oil, rust, water and other impurities.
4, corrosion resistance of deposited metal test determined by the agreement between supply and demand.
