Basic type electrode for quality butt welds in constructions under high restraint.
Exceptional weldability; either AC or DC can be used.
High elongation and impact strength.
Smooth deposit, finely rippled.
The slag can easily be removed. Re-strike is very easy.
All vehicles, frames of motor lorries, chassis repairs, shafts of trailers, reservoirs and pipelines.
All highly restrained constructions, especially cold bended profiles.
Welding of structural steel St34-St60,boiler plate HI-HIV, 17Mn4, 19Mn5, pipe steel St35-St52, St35.4-St52.4, St35.8-St45.8, StE210.7-StE385.7, hull steel A,B,D, fine grained steel StE255-StE355, WStE255 - WStE355 and cast steel GS38-GS60.
Use a short arc, keep the electrode at an angle of 90° to the work piece.
To avoid porosity, strike the electrode on a spare piece of metal and bring it back at the end of the weld without extinguishing the arc.
Operate the same way for each new weld.
At he end of each weld, come back with the electrode on the deposit to avoid the formation of a crater.
Always use very dry electrodes to obtain the highest possible mechanical characteristics.
Dry at 300 °C (570 °F) for not less than 2 hours.
