Basic electrode for fine grained or Ni-alloyed steels with a high yield strength and impact value.
Easily removable slag.
Perfectly suitable for welding Corten steel
Pressure vessels, bridges, machine constructions, shipbuilding, machine supports, tanks and pipes.
Constructions subjected to severe weather conditions.
Impact Strength Av (ISO V):
@ 20 °C > 135 J
@ 0 °C > 120 J
@-20 °C > 100 J
@-40 °C > 60 J
Maintain a short arc, the electrode almost in vertical position to the work piece.
Avoid porosities by striking the arc on a spare piece of metal. Renew this procedure for each weld. At the end of the bead come back with the arc on the deposit to avoid crater-formation.
Always use very dry electrodes to obtain the highest possible mechanical characteristics.
When necessary preheat and dry the electrodes in the Lastidry for 2 h at 300 °C (570 °F)
