Instructions:
1.The electrodes must be baked under about 350℃ for an hour before welding, and used as soon as baking is completed.
2.The stains on the weldments, such as rust, oil stains, moisture, etc., must be cleared away before welding.
3.When welding, short arc must be used and stringer bead is suitable.
