FCW M 71

Seamless copper coated metal-cored tubular wire for semi automatic gas shielded arc welding

Beschrijvingen & toepassingen

• 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

• HDM guaranteed < 4 ml/ 100g deposited metal on the whole parameter box

• No moisture pick up, excellent wire feeding properties

• Unique mechanical properties
