The electrode provides a stable arc and minimal spatter. The deposited metal has high strength and hot cracks resistance. Therefore, this electrode is suitable for welding parts made of gray, malleable and high-strength cast iron, details operating at high loads.
The welding area must be cleaned. Welding is carried out without preheating, or with a slight heating. The beads should be welded only in the lateral direction without transverse oscillations of the electrode, no more than 50 mm of weld in one pass. In multi-layer surfacing, cool every layer in the air to a temperature of 60 ° C. after welding, immediately hammer the bead
REDRYING BEFORE WELDING
At the normal storage conditions, the redrying is not required. The moisture content of the electrode coating should not exceed 0.3% before use. In case of moisture redrying is made at 180-220°C 60 min
