Description: It is a kind of medium-manganese and medium-silicon type welding wire. It matches with medium-manganese and medium-silicon type welding flux. It is not sensitive to the rust on the base metal. It has excellent bead molding and slag detach ability. Monopole of dipole. AC/DC.
Application: Used together with fused flux 350 of sintered flux 101. Used for both high speed welding and filling welding on 50kg class base metals.

Instruction:
(1) The electrodes must be baked under 350-430 C for an hour before welding, put into a can and taken as soon as they are needed.
(2) The stains on the weldments, such as rust, oilastains, moisture, etc., must be cleared away before.
