DIRECTIONS FOR USE:
Surfacing should be made on a short arc of the cleaned surface, as The weld metal is prone to the formation of pores.
In case of exceeding the permissible moisture content in the coating (0.7%) before use further electrodes are calcined at a temperature of 280-300 ° C for 40-60 minutes.
