Application / Properties:
Electrode for producing
crack- free and tough
welding joints, Weld metal
recovery is approx. 115% .
Smooth and clean welds
blending into base metal
without undercut. Good gap
bridging properties.Owing to
its double covering (up to
3.25mmǾ)
the electrode has a stable
and concentrated arc is
therefore ideally suited for
root pass and positional
welding. Welds are X-ray
quality. Suitable for
depositing layer on steels
having higher carbon Content
(up to .4).
