| Instructions | ||||||||||
| 1.The electrode extremely easy absorption of moisture,should pay attention to the storage | ||||||||||
| 2.When the packing is not good or is affected with damp,the electrodes must be baked under 70℃～80℃ for half an hour to an hour. | ||||||||||
| 3.When welding 5.0mm elctrodes,adopt big thrust,small current as far as possible to improve welding performance. | ||||||||||
| Application | ||||||||||
| It is suitable for root passes,hot passes,filler and cover passes welding as well as for capping welding.
