Description and Applications |
|
Welding of 18-8 austenitic stainless steels for chemical
apparatus, containers and plants. Slag is easy to
detach and arc is stable, less spatter loss and bead
appearance is beautiful |

Guideline in Usage
|
|
1. |
Electrodes should be re-dried at
250
∼
300℃ for one hour before use |
|
2. |
Excessively
wide weaving may cause welding defects. Keep
weaving width to less than 2.5 times electrode
diameter. |
|
3. |
Remove dirt such
as oil and dust from the groove. |
