- the welding area must be cleaned
- perform welding on cold or slightly heated material
- conduct stitches only in the longitudinal direction, without transverse oscillations of the electrode, in sections no larger than 50 (1.9) mm (inch)
- in the case of multi-layer surfaces, air-cool layer by layer to a temperature of 60°C (140°F)
- to improve the mechanical properties, it is recommended to apply a weld bead and then immediately hit it with a hammer

- the electrode ensures a stable arc and low spatter levels
- the based metal is characterized by high strength and resistance to hot cracks, therefore this electrode is suitable for repair welding of parts made of gray, forged and high-strength cast iron, as well as products operating under heavy loads
Electrodes with a nickel-iron core, intended for cold welding and surfacing of gray and malleable cast iron parts, as well as for joining cast iron and steel.
