Half-basic type electrode with mild steel core for welding cast iron. Weld deposit is non-machinable, applicable as a whole for cast iron parts, repair of casting defects, joining of cast iron to steel arc. Suitable for: Cast iron parts, repair of casting defects, joining of cast iron to steels. Mechanical properties of all-weld metal : (typical values) Tensile strength of the weld deposit is in equal to base material but almost higher

Caution:
The electrode must be welded with short arc as much as possible. But notice that it does not contact with the work piece, for it will stick. The following points must be observed while welding with this electrode:
The work piece must be clean from oil or there impurities
Only beads of 25 to 35 mm length should be welded
Just after welding, welding deposit should be pinned in order to balance the internal stress
The work piece temperature should never be upper than hand burning temperature
