DETALII
Designed for high deposition rates and fast travel speeds. Recommended for fillet, lap and butt welds on 3.2 mm (1/8 in) and thicker steel, including some low alloy steels in applications without impact strength requirements.
Caracteristici
- Rate mari de depunere si viteza mari de sudare
- Detasare usoara a zgurii
- Unghi optim de racordare
- Patrundere mare
- Rezistenta mare la fisurare
