| Instructions | |||||||||
| 1.The Electrodes must be baked under 300~350 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. | |||||||||
| Application | |||||||||
| Used for Welding carbon steel and low-alloy steel structures,such as boilers,pressure vessels,pipelines etc. | |||||||||
