 Note: welding surfaces must be clean and free of grease, the electrode, the arc with the base metal to maintain 10-20 ° angle, the proposed short-weld welding, and immediately remove welding slag, used a slower transport section welding speed, large welding (thicker than 6mm) to be heated to 150 ℃ -300 ℃. If wet, electrodes should be dried at 150 ℃ under 2 hours.
