FCW R Ni1
Description & applications
• Seamless high fill copper coated rutile cored wire for gas shielded metal arc welding
• 1 % nickel alloyed to improve sub-zero impact strength
• Single and multipass welding of cold tough steels
• High deposition rate welding can be carried out in all positions without the need to change parameters
• No moisture pick up, excellent wire feeding properties, good weldability and low spatter
