MIG Welding Over Mill Scale

During welding, mill scale hinders the flow of the liquid weld puddle. In welding processes where there is flux, ( like stick welding and flux core processes) the flux really helps the fluidity of the puddle and also scavenges the oxides into the slag. But short circuit mig relies on deoxidizers in the bare wire.
