Metal cored wires combine the high deposition rates of flux cored wires with the high efficiencies of solid wires to improve productivity. Run harder and faster with a lower heat input than solid wires.

One of the biggest benefits of metal cored wires is the reduction in pre- and post-weld activities. Due to the flux components, they can weld through mill scale, dirt and debris, and have a greater tolerance of cold steels. 

A premium quality metal-cored wire like KOBE MX-A70C6LF or NIPPON SM-3A runs much cleaner and smoother than solid wire - which means minimal to no spatter, lower fume levels, less wear and tear on tips, liners, drive rollers, etc, leading to savings in other consumable costs as well.

MIG welding with metal cored wires means an easier to operate and more forgiving arc, lower number of welding defects, better tolerance against surface contaminations and weld preparation on typical basic and synergic welding machines and keeps this advantage over solid wires while welding with controlled waveforms (pulse, SpeedArc, SpeedUp, Power Wave, or similar programs). 

Particular care needs to be taken when changing to fully synergic machines with the ability to run wires faster and harder, as solid wires are often then pushed outside the manufacturer's specifications and weld integrity is not maintained.

Metal cored wires do cost slightly more on a per kg basis than solid or flux cored wires. However, in almost all applications, labour accounts for approximately 85% of the total cost of the welding work and the significant productivity increase gained by switching to metal-cored wire will out-weigh the increase in the filler metal cost. 

 Faster, more efficient, better quality welding will decrease the largest cost component of your work – Labour.
