Description :

This electrodes is very popular for all position welding except over head /\ .
Good striking and restriking properties.
Excellent slag removal and arc transfer. Excellent bead appearance without undercut. Due to excellent ditch filler it’s known as a cold electrodes.

Application :

Welding of low carbon steel sheet structures in ships, railway, cars, pressure tanks and general structural.
