Key features
- The weld metal is of extremely high metallurgical purity, is ageing-resistant, retaining ISO-V toughness to -60°C and CTOD tested.
- Welds are of X-ray quality.
- Due to the double coating of the 2.5 mm and 3.2 mm sizes, the arc is both stable and concentrated, even at lower welding currents when positional welding, with good gap bridging characteristics.
