Why does flux core wire Weld thicker metal than MIG?
The difference between MIG and Flux-core is the electrode used and they way the melted metal is shielded from the atmosphere. In flux core welding the filler wire is filled with flux. In MIG a shielding gas is used. In FCAW the flux shields and coats the weld pool. The weld then cools slowly creating a very strong weld.
