Description :

This electrodes with medium cover is very popular for all position also for over head /\ .
Excellent striking and restriking properties.
Excellent slag removal and arc transfer.
Excellent bead appearance without undercut.
Due to excess of recovery it is economically useful for filling. Crack and ditch.

Application :

Welding of all steels up to St 52. malleable for the construction of carriages, cars and boilers as well as all other kinds of structural steel work.
