Key features
- Designed for works highly strained at static and dynamic loadings and service temperature down to -50°C
- Excellent welding characteristics in all positions except vertical down position.
- Very low spatter in both DC and AC, with a high deposition rate
- Low moisture absorption properties ensure extra low diffusible hydrogen level in the weld metal (< 4ml/100g).
- Good slag release and flat bead appearance
