PURPOSE AND FIELD OF APPLICATION
Monolith R electrodes are designed for manual arc welding conventional and critical structures of low-carbon grades of steels like DC01, DC04, DD13, FeP01, FeP03, 1.0322, 1.0335, St22, USt3, USt4, etc.
APPLICATION CONDITIONS
-designed for welding fillet, butt, overlap joints of metal from 3 up to 20 mm thickness.
- electrodes of diameter 2,0-4,0 mm are good for welding in all positions except “vertical down”; diam. 5mm - for welding in a flat position, in a horizontal position on a vertical surface, and “vertical-up” position.
- welding should be made at DC of any polarity (it is recommended by reverse one, «+» at electrode) or AC from an open-circuit voltage transformer of not less than 50±5 V.
REDRYING BEFORE WELDING
- permissible moisture content in the coating before use is not more than 0.7 %;
- when moistening redrying is required at 120±10ºC / 60 min.

Welding should be made at DC of any polarity (it is recommended by reverse one, «+» at electrode) with an arc voltage of 25...30 V or AC from an open-circuit voltage transformer of 50±5 V.
