DESCRIPTION

• Seamless copper coated metal-cored tubular wire for semi automatic gas shielded arc welding
• Single and multipass welding of CMn steels
• Optimal productivity by combining advantages of both seamless and seamed tubular wires
• Very good penetration, high tolerance to primer
• HD_M guaranteed < 4 ml/ 100g deposited metal on the whole parameter box
• No moisture pick up, excellent wire feeding properties
• Unique mechanical properties
