Description
Copper solid wire suited for universal GMAW application in structural steel engineering, and
provides excellent feeding characteristics.
Thanks to the good mechanical properties this filler wire is optimally suited for welding thickwalled
components.
The non copper coated version of the solid wire BÖHLER EMK 6 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.
