    ATTENTION:

    1. Electrode must be approved by 350-380℃ for 1 hour before welding, dry the electrode when use it.
    2. The rust, oil, water and other impurities of the weld must be removed before welding.
    3. Must use short arc welding, the swings should not be too large, narrow bead welding is appropriate.
    4. To prevent producing arc porosity, arc plate should be adopted or use return method for arc welding.
