FCW M71
Metalcored cored wire for mild steels
Product description
– Flux-cored wire with high filling coefficient for gas-shielded welding
– Slag-free
– Suitable for single- and multi-pass welding of CMn steels
– Mechanical properties comparable in all respects to the best basic wires
– Optimum productivity by combining the advantages of tubular and staple-coated wires
– Very good penetration, good weldability on pre-painted sheet metal
– HDM guaranteed at < 4 ml/ 100g of metal deposited over the entire range of usable parameters
– No moisture pick-up, excellent pay-off properties

Why choose this cored wire?
FCW M 71 is a highly productive metal-cored wire designed for MAG welding of mild and low-alloy steels.
Its excellent deposition rate, consistent cord quality and compatibility with automated systems make it the benchmark consumable for intensive production environments.
The advantages of FCW M 71 welding wire :
-Maximum productivity: up to 30% more deposit than a solid wire, ideal for high production rates.
-Stable arc and regular deposit: smooth, flawless beads with very little spatter.
-Perfect for robotized or automated welding: wire consistency, very good performance in industrial MIG/MAG processes.
-Clean finish: excellent wetting, good visual appearance, little or no retouching.
-Excellent mechanical properties: strength and elongation in line with structural steel requirements.
-Compatible with conventional gases (Ar + CO₂): no need for specialized gases.
