Recommendations - In order to avoid a vykrashivaniye it is not recommended to make a naplavka on steel more than in two layers, and on cast iron - it is more than in one layer. At big wear to build up the lower layers other electrodes, top - one layer T-620 electrode.

Repeated calcination of electrodes before welding 300 ºС within 1 hour.
