О	1,6-2,4	-

General characteristics

Self-shielding flux-cored wire is designed for mechanized arc welding of metal structures made of ordinary quality low-carbon steels and rolled steel sheets of increased strength at open-air sites.

Application

Typical objects of the wire application are as follows: technological tanks, components and parts of agricultural machinery, repair welding and surfacing of mining equipment, parts and components of railroad cars etc.
