ATTENTION:

1. It is easy to expose to moisture, please keep it in dry condition.

2. It needs heating when package breaks or moisture absorbed, heating temperature should be between 70C to 80C, heating time should be from 0.5 to 1 hour.

3. When using 5.0mm welding electrodes, it’s better to use high-thrust, low-current, in order to enhance welding performance.
