Description
Copper solid wire used for GMAW of structural components with increased strength requirements
and is optimally suited for welding thick-walled components.
BÖHLER EMK 8 is designed for semi-automatic and robotic welding and provides excellent
feeding characteristics. The non copper coated version of the solid wire BÖHLER EMK 8 TOP
is designed for low spatter formation and excellent feeding properties for extremely high wire
feed rates. These types are especially suited for robotic welding.
