Additional Information
- Redrying, if necessary, 2h/300°C.
- Hold electrode almost vertically with a short arc.
- On materials sensitive to cracks a buffer-layer with 18/8Mn [AS-300] is recommended.
- Low alloyed, high carbon tool steels etc. should be preheated to 200 – 400°C, depending on their composition and thickness.
- Slow cooling in still air after surfacing.
