FCW R 71
Description & applications
• Seamless copper coated wire for flux cored arc welding with a gas shield.
• Rutile, fast freezing slag for all positional welding.
• Single and multiple pass welding of CMn steels.
• No moisture pick up, excellent wire feeding properties.
• For use with mixed gas.
