FCW M Ni1
Description & applications
• Seamless high fill copper coated metal-cored tubular wire for gas shielded metal arc welding
• 1 % nickel alloyed to improve sub-zero impact strength
• Single and multipass welding of cold tough steels
• Optimal productivity by combining advantages of both seamless and seamed tubular wires
• HDM guaranteed < 4 ml/ 100g deposited metal on the whole parameter box
• No moisture pick up, excellent wire feeding properties, good weldability and low spatter
