Characteristics and field of use
GMAW solid wire electrode for welding unalloyed and low alloy steels with CO2 or gas 
spatter transfer in short and spray arc range. High arc stability also at high welding current amperage.
Large application range specially suited for steels of higher strength in boiler and
pipeline construction， shipbuilding， vehicle manufacturing and structural engineering.
